# Glosario
Este documento está diseñado para ofrecer definiciones de varios términos, exclusivos
de WordPress, con los que los usuarios pueden no estar familiarizados.
Si eres un colaborador, **por favor**, no añadas definiciones para términos genéricos(
API, PHP, JavaScript, etc…).
## Ruta absoluta
_(también conocida como **ruta completa**)_
La ubicación completa de un archivo o directorio dentro del sistema de archivos
de un ordenador. Una ruta absoluta comienza en el directorio raíz (o letra del disco)
y continúa subiendo por la jerarquía de directorios hasta alcanzar el archivo o
directorio específico. Esto contrasta con una [ruta relativa](https://es.wordpress.org/support/article/glossary/?output_format=md#ruta-relativa),
que no empieza en el directorio raíz.
La sintaxis de las rutas absolutas difiere según el sistema operativo. En Microsoft
Windows, comienzan con una letra de un disco y usan una barra invertida para separar
los nombres de los directorios. Las rutas absolutas en MacOS y Linux carecen de
letras de disco y usan una barra inclinada hacia delante como separador de directorios.
Ejemplos:
* Windows: `C:\Users\Juan\www\blog\images\helado.jpg`
* MacOS: `/Users/Juan/www/blog/images/helado.jpg`
* Linux: `/home/Juan/www/blog/images/helado.jpg`
Para encontrar la ruta absoluta del sistema de archivos del directorio que contiene
una página web, copia el código que aparece a continuación en un nuevo archivo de
texto, guarda el archivo como _path.php_ (haciendo así una simple página web PHP)
y mueve ese archivo a tu [servidor web](https://es.wordpress.org/support/article/glossary/?output_format=md#servidor-web).
A continuación, dirige tu navegador web a la dirección [URL](https://es.wordpress.org/support/article/glossary/?output_format=md#url)
de ese archivo (por ejemplo, [https://www.example.com/path.php](https://www.example.com/path.php)).
```wp-block-preformatted
```

## URI absoluta
_(también conocida como **URI completa**)_
Una URI contiene la ubicación completa de un recurso (a diferencia de una [URI relativa](https://es.wordpress.org/support/article/glossary/?output_format=md#uri-relativa)).
Ejemplos:
* `http://www.example.com/blog/images/helado.jpg`
* `ftp://ftp.example.com/users/h/juan/www/`
## Acción
En WordPress una acción es una [función PHP](https://www.w3schools.com/php/php_functions.asp)
que se ejecuta en puntos específicos a lo largo del núcleo de WordPress.
Los desarrolladores pueden crear una acción **personalizada** usando la [API de acciones](https://developer.wordpress.org/reference/functions/add_action/)
para añadir o eliminar código de una acción existente especificando cualquier [gancho existente](https://codex.wordpress.org/Plugin_API/Action_Reference).
Este proceso se denomina «[enganche](https://es.wordpress.org/support/article/glossary/?output_format=md#gancho)».
**Por ejemplo**: Un desarrollador puede querer **añadir** código en el pie de página
de un tema. Esto se podría lograr escribiendo una nueva función y, después, engancharla
a la acción `[wp_footer](https://codex.wordpress.org/Plugin_API/Action_Reference/wp_footer)`.
**Las acciones personalizadas difieren de los _[filtros](https://es.wordpress.org/support/article/glossary/?output_format=md#filtro)_
personalizados** porque las acciones personalizadas te permiten **añadir o eliminar**
código de las acciones existentes. Mientras que los filtros personalizados te permiten**
reemplazar** datos específicos (como una variable) que se encuentren dentro de una
acción existente.

## Barra de administración
Un área de la pantalla justo encima de tu sitio que te da acceso rápido a características
como añadir una nueva entrada o editar tu perfil. Solo es visible si estás conectado.
El concepto de la barra de administración fue añadido a WordPress en la [versión 3.1](https://wordpress.org/support/wordpress-version/version-3-1/)
y fue reemplazado por la [barra de herramientas](https://es.wordpress.org/support/article/toolbar/?output_format=md)
en la [versión 3.3](https://wordpress.org/support/wordpress-version/version-3-3/)
de WordPress. Para activarla (o desactivarla), abre el escritorio y navega a [Administración](https://es.wordpress.org/support/article/administration-screens/?output_format=md)
> [Usuarios](https://es.wordpress.org/support/article/administration-screens/?output_format=md#tu-perfil)
> [Tu perfil](https://es.wordpress.org/support/article/users-your-profile-screen/?output_format=md).

* Ver también: [Tu pantalla de perfil](https://es.wordpress.org/support/article/users-your-profile-screen/?output_format=md).
## Ajax
**Ajax** es una técnica que usan las páginas web para hacer que el servidor realice
cierto proceso sin recargar la página web. Por ejemplo, cuando apruebas un comentario
en un blog WordPress, WordPress usa Ajax para cambiar el estado del comentario y
puedes ver el cambio sin tener que recargar la pantalla de comentarios.
* Artículo relacionado: [Ajax](https://codex.wordpress.org/AJAX).

## Apache
Apache es el nombre abreviado del **[proyecto de servidor HTTP Apache](https://httpd.apache.org/)**,
un software de servidor web HTTP de código abierto, robusto, de calidad comercial,
lleno de características y disponible gratuitamente, elaborado por la [Apache Software Foundation](https://www.apache.org/).
Es el servidor web más utilizado en Internet y está disponible para muchas plataformas,
incluyendo Windows, [Unix](https://es.wordpress.org/support/article/glossary/?output_format=md#unix)/
[Linux](https://es.wordpress.org/support/article/glossary/?output_format=md#linux)
y [Mac OS X](https://es.wordpress.org/support/article/glossary/?output_format=md#mac-os-x).
Apache constituye una gran base para la publicación de sitios WordPress.
## API
Por favor, consulta la [página de Wikipedia](https://es.wikipedia.org/wiki/Interfaz_de_programaci%C3%B3n_de_aplicaciones)
para obtener la definición.
## Array
Un **array** es una de las estructuras básicas de datos usadas en la programación
de ordenadores. Un _array_ contiene una lista (o vector) de elementos, como valores
numéricos o de cadena. Los _arrays_ permiten a los programadores acceder aleatoriamente
a los datos. Los datos pueden ser almacenados en _arrays_ _unidimensionales_ o _multidimensionales_.
Un array unidimensional de siete (7) elementos sería:
| 105 | 200 | 54 | 53 | 102 | 13 | 405 |
La [etiqueta de plantilla](https://codex.wordpress.org/es:Template_Tags) `[wp_list_categories()](https://developer.wordpress.org/reference/functions/wp_list_categories/)`
usa un array unidimensional para el parámetro `exclude`.
Un ejemplo de un array bidimensional, de 7 por 3 elementos en tamaño, sería:
| 105 | 200 | 54 | 53 | 102 | 13 | 405 |
| 15 | 210 | 14 | 513 | 2 | 2313 | 4512 |
| 501 | 500 | 499 | 488 | 552 | 75 | 1952 |
* Enlaces externos: [Programación de arrays en Wikipedia](https://en.wikipedia.org/wiki/Array_programming),
[Array en freedictionary.com](https://encyclopedia.thefreedictionary.com/array).
## ASCII
**ASCII** (pronunciado en inglés como «ask ii») es un [conjunto de caracteres](https://es.wordpress.org/support/article/glossary/?output_format=md#conjunto-de-caracteres)
estándar, pero limitado, que contiene solo letras, números, algunos símbolos comunes
y signos de puntuación comunes en inglés. El [contenido](https://es.wordpress.org/support/article/glossary/?output_format=md#contenido)
de WordPress no está limitado a ASCII, sino que puede incluir cualquier carácter
[Unicode](https://es.wordpress.org/support/article/glossary/?output_format=md#unicode).
ASCII son las siglas de **A**merican **S**tandard **C**ode for **I**nformation **
I**nterchange.
* Enlace externo: [ASCII](https://es.wikipedia.org/wiki/ASCII) (Wikipedia, con
la tabla del conjunto de caracteres).
## Atom
Un formato para la sindicación de contenido en sitios de noticias, que puede ser
visualizado por los programas de software Atom, llamados lectores o agregadores
de noticias.
* Ver también: [Lector de noticias](https://es.wordpress.org/support/article/glossary/?output_format=md#lector-de-noticias),
[RSS](https://es.wordpress.org/support/article/glossary/?output_format=md#rss),
[RDF](https://es.wordpress.org/support/article/glossary/?output_format=md#rdf).
* Enlace externo: [Atom (estándar) en Wikipedia](https://es.wikipedia.org/wiki/Atom_(formato_de_redifusi%C3%B3n)).
## Guardado automático
Cuando estás escribiendo o editando tus entradas y páginas, los cambios que haces
se guardan automáticamente cada 2 minutos. En la esquina inferior derecha del editor,
verás un aviso sobre cuándo se ha guardado la entrada en la base de datos por última
vez. Los guardados automáticos están activados automáticamente para todas las entradas
y páginas. Solo hay un guardado automático para cada entrada/página. Cada nuevo
guardado automático sobrescribe el anterior en la base de datos.

## Avatar
Un **avatar** es una imagen gráfica o una foto que representa al usuario.
* Ver también: [Gravatar](https://es.wordpress.org/support/article/glossary/?output_format=md#gravatar).
* Artículo relacionado: [Cómo usar los gravatars](https://es.wordpress.org/support/article/how-to-use-gravatars/?output_format=md).
* Enlace externo: [Avatar (Internet) en Wikipedia](https://es.wikipedia.org/wiki/Avatar_(Internet)).
## Administración
La administración es el área a la que pueden acceder los usuarios autorizados para
añadir, eliminar y modificar los contenidos de la web. También puede denominarse
como «WordPress», «escritorio» o «área de administración».
## Binarios
Los **binarios** se refieren a programas compilados de ordenador o ejecutables.
Muchos proyectos de [código abierto](https://es.wikipedia.org/wiki/Sistema_de_c%C3%B3digo_abierto),
que pueden ser recompilados desde el [código fuente](https://es.wikipedia.org/wiki/C%C3%B3digo_fuente),
ofrecen binarios precompilados para las plataformas y sistemas operativos más populares.
## Blog
Un **blog**, o **weblog**, es un periódico, un diario o serie online publicados
por una persona o un grupo de personas.
Los blogs son usados normalmente por particulares o grupos de compañeros, pero también,
en algunos casos, son usados por empresas u organizaciones. En el ámbito empresarial,
los únicos que hasta ahora han adoptado el formato de blog, han tendido a ser firmas
de diseño, empresas de medios web y otras firmas «vanguardistas» de tecnología.
Los blogs suelen tener contenido tanto público como privado. Dependiendo de la funcionalidad
del software [CMS](https://es.wordpress.org/support/article/glossary/?output_format=md#sistema-de-gesti%c3%b3n-de-contenidos)
que se use, algunos autores pueden restringir el acceso —a través del uso de cuentas
o contraseñas— a contenido que es demasiado personal para ser publicado públicamente.
## Bloguear
**Bloguear** es el acto de escribir en tu propio blog. _Bloguear_ algo es escribir
sobre algo en el blog de uno mismo. A veces, esto implica [enlazar](https://es.wikipedia.org/wiki/Hiperenlace)
con algo en Internet que el autor considera interesante.
* Ver también: [Blogosfera](https://es.wordpress.org/support/article/glossary/?output_format=md#blogosfera)
y [blogroll](https://es.wordpress.org/support/article/glossary/?output_format=md#blogroll).
## Blogosfera
La **blogosfera** es el subconjunto de webs en Internet que son o están relacionados
con los [blogs](https://es.wordpress.org/support/article/glossary/?output_format=md#blog).
* Ver también: [Blog](https://es.wordpress.org/support/article/glossary/?output_format=md#blog)
y [blogroll](https://es.wordpress.org/support/article/glossary/?output_format=md#blogroll).
## Blogroll
A **blogroll** is a list of links to various blogs or news sites. Often a blogroll
is «rolled» by a service which tracks updates (using [feeds](https://es.wordpress.org/support/article/glossary/?output_format=md#feed))
to each site in the list, and provides the list in a form which aggregates update
information. The default blogroll (aka links) included in WordPress was removed
in version 3.5.

[News reader](https://es.wordpress.org/support/article/glossary/?output_format=md#news-reader)
* External links: [News aggregator at Wikipedia](http://en.wikipedia.org/wiki/News_aggregator)
## Bookmarklet
A **bookmarklet** (or **favelet**) is a «faux» bookmark containing scripting code,
usually written in [JavaScript](https://codex.wordpress.org/Glossary#javascript),
that allows the user to perform a function.
Examples:
* The [delicious.com bookmarklets](http://delicious.com/help/bookmarklets) allow
a user to quickly post a link to his/her delicious.com bookmarks list.
* [Tantek’s favelets](http://tantek.com/favelets/)
## Booleano
A variable or expression which evaluates to either true or false.
* External links: [PHP Boolean data type](http://us2.php.net/manual/en/language.types.boolean.php)
## Categoría
Each [post](https://codex.wordpress.org/Glossary#Post) in WordPress can be filed
under one or more **categories**. Thoughtful categorization allows posts to be grouped
with others of similar content and aids in the navigation of a site.
Please note that a **post** category should not be confused with a [**link** category](https://codex.wordpress.org/Administration_Panels#Link_Categories),
which is used to classify and manage [links](https://codex.wordpress.org/Administration_Panels#Links_-_Putting_the_Inter_in_the_Internet).
## Capacidades
A **capability** is permission to perform one or more types of task. Each user of
a WordPress site might have some permissions but not others, depending on their
[role](https://codex.wordpress.org/Glossary#Role). For example, users who have the
Author role usually have permission to edit their own posts (the «edit_posts» capability),
but not permission to edit other users’ posts (the «edit_others_posts» capability).
WordPress comes with six roles and over fifty capabilities in its role-based access
system. Plugins can modify the system.
* Related article: [Roles and Capabilities](https://codex.wordpress.org/Roles_and_Capabilities)
* External link: [Role-based access control](http://en.wikipedia.org/wiki/Role-based_access_control)(
Wikipedia)
## CGI
**CGI** (Common Gateway Interface) is a specification for [server-side](http://en.wikipedia.org/wiki/Server-side)
communication scripts designed to transfer information between a [web server](https://codex.wordpress.org/Glossary#Web_server)
and a [web-client (browser)](http://en.wikipedia.org/wiki/Client-side). Typically,
[HTML](https://codex.wordpress.org/Glossary#HTML) pages that collect data via forms
use _CGI_ programming to process the form data once the client submits it.
## Entidades de caracteres
A **character entity** is a method used to display _special characters_ normally
_reserved_ for use in [HTML](https://codex.wordpress.org/Glossary#HTML). For example,
the _less than_ (**<**) and _greater than_ (**>**) are used as part the [HTML](https://codex.wordpress.org/Glossary#HTML)
tag structure, so both symbols are _reserved_ for that use. But, if you need to
display those symbols on your site, you can use _character entities_. For example:
use **`<`** for the less than (<) symbol use **`>`** for the greater than(
>) symbol
* Related articles: [Fun Character Entities](https://codex.wordpress.org/Fun_Character_Entities)
## Conjunto de caracteres
A **character set** is a collection of symbols (letters, numbers, punctuation, and
special characters), when used together, represent meaningful words in a language.
Computers use an encoding scheme so members of a character set are stored with a
numeric value (e.g. 0=A, 1=B, 2=C, 3=D). In addition, a [collation](https://codex.wordpress.org/Glossary#Collation)
determines the order (i.e alphabetic) to use when sorting the character set.
By default, WordPress uses the Unicode UTF-8 (**utf8**) character set for the [WordPress MySQL database tables](https://codex.wordpress.org/Database_Description)
created during the [installation process](https://codex.wordpress.org/Installing_WordPress).
Beginning with [Version 2.2](https://codex.wordpress.org/Version_2.2), the database
character set (and collation) is defined in the _wp-config.php_ file.
* See also: [Collation](https://codex.wordpress.org/Glossary#Collation)

[Character sets and collation at MySQL](http://dev.mysql.com/doc/refman/5.0/en/charset-general.html)
## chmod
**chmod** is a [Unix](https://codex.wordpress.org/Glossary#Unix)/[Linux](https://codex.wordpress.org/Glossary#Linux)
[shell](https://codex.wordpress.org/Glossary#Shell) command used to change [permissions](https://codex.wordpress.org/Glossary#Permissions)
on files. Its name is a contraction of «**ch**ange **mod**e.»
* Related articles: [Changing File Permissions](https://codex.wordpress.org/Changing_File_Permissions),
[UNIX Shell Skills](https://codex.wordpress.org/UNIX_Shell_Skills), [htaccess for subdirectories](https://codex.wordpress.org/htaccess_for_subdirectories)
## Clase
**Classes** are groupings of [CSS](https://codex.wordpress.org/Glossary#CSS) styles
which can be applied to any [HTML](https://codex.wordpress.org/Glossary#HTML) element.
For classes in PHP, see the [Class (Computing)](http://en.wikipedia.org/wiki/Class#Computing)
article at Wikipedia and [PHP Manual: Classes and Objects](http://php.net/manual/en/language.oop5.php).
* Related articles: [CSS](https://codex.wordpress.org/CSS), [Blog Design and Layout](https://codex.wordpress.org/Blog_Design_and_Layout)
## Codex
The **Codex** is the series of articles that show users how to use WordPress. WordPress
users contribute documentation to the codex voluntarily.
* External links: [Codex](https://codex.wordpress.org/Main_Page)
## Colación
**Collation** refers to the order used to sort the letters, numbers, and symbols
of a given [character set](https://codex.wordpress.org/Glossary#Character_set).
For example, because WordPress, by default, uses the UTF-8 (**utf8**) character
set, and when the [WordPress MySQL database tables](https://codex.wordpress.org/Database_Description)
are created during the [installation process](https://codex.wordpress.org/Installing_WordPress),
MySQL assigns **utf8_general_ci** collation to those tables. Beginning with [Version 2.2](https://codex.wordpress.org/Version_2.2),
the collation (and character set) used by WordPress is defined in the _wp-config.
php_ file.

## Comentarios
**Comments** are a feature of [blogs](https://codex.wordpress.org/Glossary#Blog)
which allow readers to respond to [posts](https://codex.wordpress.org/Glossary#Post).
Typically readers simply provide their own thoughts regarding the [content](https://codex.wordpress.org/Glossary#Content)
of the post, but users may also provide [links](http://en.wikipedia.org/wiki/Hyperlink)
to other resources, generate discussion, or simply compliment the author for a well-
written post.
You can control and regulate comments by filters for language and content. Comments
can be queued for approval before they are visible on the web site. This is useful
in dealing with [comment spam](https://codex.wordpress.org/Comment_Spam).

* External links: [Hyperlink at Wikipedia](http://en.wikipedia.org/wiki/Hyperlink)
## Contenido
**Content** consists of text, images, or other information shared in [posts](https://codex.wordpress.org/Glossary#Post).
This is separate from the structural design of a web site, which provides a framework
into which the content is inserted, and the presentation of a site, which involves
graphic design. A [Content Management System](https://codex.wordpress.org/Glossary#Content_Management_System)
changes and updates content, rather than the structural or graphic design of a web
site.
## Sistema de gestión de contenidos
A **Content Management System**, or **CMS**, is software for facilitating the maintenance
of [content](https://codex.wordpress.org/Glossary#Content), but not design, on a
web site. A [blogging](https://codex.wordpress.org/Glossary#Blog) tool is an example
of a Content Management System.
* See also: [Blog](https://codex.wordpress.org/Glossary#Blog)
## cPanel
**cPanel** is a popular web-based administration tool that many [hosting providers](https://codex.wordpress.org/Glossary#Hosting_provider)
provide to allow users to configure their own accounts using an easy-to-use interface.
* Related articles: [Using cPanel](https://codex.wordpress.org/Using_cPanel),

* External links: [cPanel website](http://cpanel.net/)
## CSS
**CSS**, or **Cascading Style Sheets**, is a [W3C](http://www.w3.org/) [open standards](http://en.wikipedia.org/wiki/Open_standard)
programming language for specifying how a web page is presented. It allows web site
designers to create formatting and layout for a web site independently of its content.

* External links: [CSS at W3C](http://www.w3.org/Style/CSS/), [Open standards at Wikipedia](http://en.wikipedia.org/wiki/Open_standard),
[W3C.org](http://www.w3.org/)
## CVS
**CVS** stands for **Concurrent Versions System** and is the software that used
to be used coordinate WordPress development. As of February 2005, this function
is carried out by Subversion ([SVN](https://codex.wordpress.org/Glossary#SVN)).
For more information on Subversion, see [Using Subversion](https://codex.wordpress.org/Using_Subversion).
## Escritorio
In WordPress a **Dashboard** is the main administration screen for a site (a weblog),
or for a network of sites. It summarizes information about the site or network,
and also external information, in one or more [widgets](https://codex.wordpress.org/Glossary#Widget)
that the Dashboard user can enable, disable, and move around.
* Related articles: [Dashboard Screen](https://codex.wordpress.org/Dashboard_Screen)
## Base de datos
A **database** in computing terms is software used to manage information in an organized
fashion. [WordPress](https://codex.wordpress.org/Glossary#WordPress) uses the [MySQL](https://codex.wordpress.org/Glossary#MySQL)
or [MariaDB](https://codex.wordpress.org/Glossary#MariaDB) relational databases
management system for storing and retrieving the content of your [blog](https://codex.wordpress.org/Glossary#Blog),
such as [posts](https://codex.wordpress.org/Glossary#Posts), [comments](https://codex.wordpress.org/Glossary#Comments),
and so on.
* Related articles: [Database Description](https://codex.wordpress.org/Database_Description),
[Backing Up Your Database](https://codex.wordpress.org/Backing_Up_Your_Database)
## Versión de la base de datos
In WordPress, the **database version** is a number that increases every time changes
are made to the way WordPress organizes the data in its [database](https://codex.wordpress.org/Glossary#database).
It is not the same as the version of the database software, [MySQL](https://codex.wordpress.org/Glossary#MySQL)
or [MariaDB](https://codex.wordpress.org/Glossary#MariaDB).
For example, the database version in WordPress 3.3 was 19470, and the database version
in WordPress 3.3.1 did not change. This tells anyone planning to use backed-up data
from the older version that they do not need to check for changes in the structure
of the data.
WordPress stores its database version in the database, as the option named «db_version»
in every WordPress site’s «wp_options» table. (The table name prefix «wp_» may be
missing or different in some cases.)
* Related articles: [Database Description](https://codex.wordpress.org/Database_Description),
[How do you force a database upgrade?](https://codex.wordpress.org/FAQ_Installation#How_do_you_force_a_database_upgrade.3F)
## Tema por defecto
Every installation of WordPress has a [default theme](https://codex.wordpress.org/Glossary#Default_theme).
The default theme is sometimes called the **fallback theme**, because if the active
theme is for some reason lost or deleted, WordPress will fallback to using the default
theme.
The WordPress default themes have been:
* Up to [Version 2.9.2](https://codex.wordpress.org/Version_2.9.2) the default
theme was the WordPress Default theme (sometimes called Kubrick) and was located
in the _wp-content/themes/default_ folder.

## Desarrollador
A **developer**, or **dev**, is a computer programmer who is active in creating,
modifying, and updating a software product.

## DIV
A **DIV** element in [HTML](https://codex.wordpress.org/Glossary#HTML) marks a section
of text. DIVs are used extensively in WordPress to apply [CSS](https://codex.wordpress.org/Glossary#CSS)
stylings to particular [blog](https://codex.wordpress.org/Glossary#Blog) elements.

## DNS
**DNS**, the domain name system, is the system that maps [domain names](https://codex.wordpress.org/Glossary#Domain_name)
to [IP addresses](https://codex.wordpress.org/Glossary#IP_address). When you use
a web browser to visit a website, your browser first extracts the site’s domain
name from the URL. Then it uses the DNS to find the IP address for that domain name.
Then it connects to that IP address.
* External link: [Domain Name System](http://en.wikipedia.org/wiki/Domain_Name_System)(

## DOM
**DOM** (Document Object Model) is a standard, platform-independent interface that
allows programmers to dynamically access HTML and XML to control the content and
structure of documents. DOM connects programming scripts to web pages.
* External links: [DOM at Wikipedia](http://en.wikipedia.org/wiki/Document_Object_Model),
[DOM at W3C.org](http://www.w3.org/DOM/)
## Nombre de dominio
A **domain name** is a name used for identification purposes on the Internet. In
WordPress a domain name usually identifies a server where WordPress is installed.
To make this work, the Internet’s domain name system ([DNS](https://codex.wordpress.org/Glossary#DNS))
maps the domain name to a server’s [IP address](https://codex.wordpress.org/Glossary#IP_address).
For example, the domain name _example.com_ maps to the IP address _192.0.43.10_.
Many domain names can map to the same IP address, allowing a single server to run
many websites. For example, the domain names _www.example.com_ and _example.net_
also map to the IP address _192.0.43.10_.
* External link: [Domain name](http://en.wikipedia.org/wiki/Domain_name) (Wikipedia)
## Borrador
The **draft** [post status](https://codex.wordpress.org/Glossary#Post_status) is
for WordPress [posts](https://codex.wordpress.org/Glossary#Post) which are saved,
but as yet unpublished. A draft post can only be edited through the [Administration Panel](https://codex.wordpress.org/Administration_Panels),
[Write Post SubPanel](https://codex.wordpress.org/Write_Post_SubPanel) by [users](https://codex.wordpress.org/Authors_and_Users_SubPanel#Table_of_Authors)
of equal or greater [User Level](https://codex.wordpress.org/User_Levels) than the
[post’s author](https://codex.wordpress.org/Authors_and_Users_SubPanel#Table_of_Registered_Users).
## Extracto
An **excerpt** is a condensed description of your blog [post](https://codex.wordpress.org/Glossary#Post)
and refers to the summary entered in the Excerpt field of the [Administration](https://codex.wordpress.org/Administration_Panels)
> [Posts](https://codex.wordpress.org/Administration_Panels#Add_New_Post) > [Add New SubPanel](https://codex.wordpress.org/Posts_Add_New_SubPanel).
The _excerpt_ is used to describe your post in RSS feeds and is typically used in
displaying search results. The _excerpt_ is sometimes used in displaying the **Archives**
and [Category](https://codex.wordpress.org/Glossary#Category) views of your posts.
Use the [Template Tag](https://codex.wordpress.org/Template_Tags) [the_excerpt()](https://codex.wordpress.org/Template_Tags/the_excerpt)
to display the contents of this field. Note that if you do not enter information
into the Excerpt field when writing a post, and you use [the_excerpt()](https://codex.wordpress.org/Template_Tags/the_excerpt)
in your theme template files, WordPress will automatically display the first 55
words of the [post](https://codex.wordpress.org/Glossary#Post)‘s content.
An _excerpt_ should not be confused with the **teaser**, which refers to words before
the ` ` in a [post’s](https://codex.wordpress.org/Glossary#Post) content.
When typing a long post you can insert the ` ` [Quicktag](https://codex.wordpress.org/Posts_Add_New_SubPanel#Visual_Versus_HTML_Editor)
after a few sentences to act as a cut-off point. When the post is displayed, the**
teaser**, followed by a hyperlink (such as **Read the rest of this entry…**), is
displayed. Your visitor can then click on that link to see the full version of your
[post](https://codex.wordpress.org/Glossary#Post). The [Template Tag](https://codex.wordpress.org/Template_Tags),
[the_content()](https://codex.wordpress.org/Template_Tags/the_content) should be
used to display the teaser.

## Feed
A **feed** is a function of special software that allows «Feedreaders» to access
a site automatically looking for new content and then posting the information about
new content and updates to another site. This provides a way for users to keep up
with the latest and hottest information posted on different blogging sites. Some
Feeds include RSS (alternately defined as «Rich Site Summary» or «Really Simple
Syndication»), Atom or RDF files. Dave Shea, author of the web design weblog [Mezzoblue](http://mezzoblue.com)
has written [a comprehensive summary](http://www.mezzoblue.com/archives/2004/05/19/what_is_rssx/)
of feeds. Feeds generally are based on [XML](https://codex.wordpress.org/Glossary#XML)
technology.
## Lector de feeds
The role of Feedreader is to gather and display the webfeed from various website
to one place.
## Filtro
In WordPress, a Filter is a [function](http://www.w3schools.com/php/php_functions.asp)
that is associated with an existing [Action](https://codex.wordpress.org/Glossary#Action)
by specifying any [existing Hook](https://codex.wordpress.org/Plugin_API/Action_Reference).
Developers can create [**custom** Filters](https://codex.wordpress.org/Function_Reference/add_filter)
using the [Filter API](https://codex.wordpress.org/Plugin_API/Filter_Reference)
to **replace** code from an existing Action. This process is called «[hooking](https://codex.wordpress.org/Glossary#Hook)«.
**Custom Filters differ from custom _[Actions](https://codex.wordpress.org/Glossary#Action)_**
because custom Actions allow you to **add or remove** code from existing Actions.
Whereas custom Filters allow you to **replace** specific data (such as a variable)
found within an existing Action.

## Área del pie de página
A **footer area** is a horizontal area provided by a [theme](https://codex.wordpress.org/Glossary#Theme)
for displaying information other than the main [content](https://codex.wordpress.org/Glossary#Content)
of the web page. Themes may provide one or more footer areas below the content.
Footer areas usually contain [widgets](https://codex.wordpress.org/Glossary#Widget)
that an administrator of the site can customize.
In a theme, footer areas are generated by a [template](https://codex.wordpress.org/Glossary#Template)
file, typically named _sidebar-footer.php_.

## Portada
The front end is what your visitors see and interact with when they come to your
website, www.YourSite.com.
## FTP
**FTP**, or **File Transfer Protocol**, is a client-server protocol for transferring
files. It is one way to download files, and the most common way to upload files
to a server.
An FTP _client_ is a program which can download files from, or upload files to,
an FTP _server_.
You may need to use an FTP client to upload your WordPress files to your [web server](https://codex.wordpress.org/Glossary#Web_server),
particularly if you use a [hosting provider](https://codex.wordpress.org/Glossary#Hosting_provider).
* Related articles: [FTP Clients](https://codex.wordpress.org/FTP_Clients), [Uploading WordPress to a remote host](https://codex.wordpress.org/Uploading_WordPress_to_a_remote_host),

## Galería
As defined by Andy Skelton, **Gallery**, introduced with [WordPress 2.5](https://codex.wordpress.org/Version_2.5),
is specifically an exposition of images attached to a post. In that same vein, an
upload is «attached to a post» when you upload it while editing a post.
In the uploader there is a «Gallery» tab that shows all the uploads attached to
the post you are editing. When you have more than one attachment in a post, you
should see at the bottom of the Gallery tab a button marked «Insert gallery». That
button inserts a shortcode «» into the post. WordPress replaces that shortcode with
an exposition of all images attached to that post. Non-image file types are excluded
from the gallery.
Note: If you don’t see the «Insert gallery» button, it may be because you have not
attached two images to the post.
The pretty URLs for attachments are made only after you have published the post
and should be composed as the post [permalink](https://codex.wordpress.org/Glossary#permalink)
plus the attachment [slug](https://codex.wordpress.org/Glossary#slug).

## gettext
The **gettext** system is a set of tools and standards for language translation,
used by WordPress to provide versions in many languages. In WordPress a text string
for translation may have a domain and a context. For example, a plugin might specify
its own domain for translations, and a context might help translators to provide
different translations of the same English word or phrase in different parts of
the user interface.

## GMT
**GMT** («Greenwich Mean Time», the time at the Royal Observatory in Greenwich,
England) is the old name of the time zone from which all other time zones were measured.
It has been replaced by [UTC](https://codex.wordpress.org/Glossary#UTC) («Universal
Time, Coordinated»), but for most practical purposes UTC and GMT are the same, so
the term GMT is still commonly used.

## Gravatar
A **gravatar** is a globally recognized [avatar](https://codex.wordpress.org/Glossary#Avatar)(
a graphic image or picture that represents a user). Typically a user’s gravatar
is associated with their email address, and using a service such as [Gravatar.com](http://en.gravatar.com/).
The site owner to can configure their site so that a user’s gravatar is displayed
along with their comments.

## GUI
GUI stands for Graphical User Interface, pronounced as «gooey». It is an interface
that allows users to point the mouse or cursor to graphical icons.
## Gutenberg
Gutenberg is newly developed, block-oriented editor. It uses blocks to create all
types of content, replacing a half-dozen inconsistent ways of customizing WordPress,
bringing it in line with modern coding standards, and aligning with open web initiatives.
These content blocks transform how users, developers, and hosts interact with WordPress
to make building rich web content easier and more intuitive, democratizing publishing—
and work — for everyone, regardless of technical ability.
## Hack
A **hack** is a bit of code written to customize or extend the functionality of
a software product. Older versions of WordPress used a hack-based extension system,
but versions [1.2](https://codex.wordpress.org/Changelog/1.2) and above of WordPress
use a [Plugin API](https://codex.wordpress.org/Plugin_API) with [hooks](https://codex.wordpress.org/Glossary#Hook)
for extensions.
* See also: [Hacking](https://codex.wordpress.org/Glossary#Hacking), [Plugin](https://codex.wordpress.org/Glossary#Plugin)

* External links: [Open source at Wikipedia](http://en.wikipedia.org/wiki/Open_source)
## Hacking
**Hacking** is the process of writing code for, or contributing code to, a piece
of software.
There is some controversy surrounding the meaning of this term. It began as a benign
term meaning «to exercise proficiency» or «to alter or improve,» but the popular
media have since construed it to mean «to break into a computer system, usually
with malicious intent.» Many in the computer industry have recently begun trying
to ‘take back’ the word from its popular mutation, and many have adopted the term
_cracking_ to replace the malicious interpretation. Because of the desire to reclaim
the word, you will often find the term used in conjunction with [open source](http://en.wikipedia.org/wiki/Open_source)
projects, intended in its benign form. For more information about the history of
the term, please see [Wikipedia’s article on _Hacker_](http://en.wikipedia.org/wiki/Hacker).

## Imagen de la cabecera
A **Header Image** is a wide picture that appears at the top of a WordPress website.
## Gancho
Hooks are specified, by the developer, in Actions and Filters. Here is a (hopefully)
complete list of all [existing Hooks](https://codex.wordpress.org/Plugin_API/Action_Reference)
within WordPress.
Because Hooks are required by Actions and Filter you may hear the phrase «Action
Hooks» and «Filter Hooks» used from time to time.
In technical and strict terms: a Hook is an event, i.e. event as understood by [Observer pattern](http://en.wikipedia.org/wiki/Observer_pattern),
invoked by the [do_action()](https://codex.wordpress.org/Function_Reference/do_action)
or [apply_filters()](https://codex.wordpress.org/Function_Reference/apply_filters)
call that afterwards triggers all the [action](https://codex.wordpress.org/Glossary#Action)
or [filter](https://codex.wordpress.org/Glossary#Filter) functions, previously hooked
to that event using [add_action()](https://codex.wordpress.org/Function_Reference/add_action)
or [add_filter()](https://codex.wordpress.org/Function_Reference/add_filter), respectively.

### Confusión de la terminología
WordPress Codex and source code comments sometimes confuse the terms «[actions](https://codex.wordpress.org/Glossary#Action)/
[filters](https://codex.wordpress.org/Glossary#Filter)» and «[hooks](https://codex.wordpress.org/Glossary#Hook)«.
Actions, Filters and Hooks are also occasionally referred to as «action/filter hooks»
or «action/filter/hook functions».
## Proveedor de alojamiento
A **hosting provider** is a company or organization which provides, usually for
a fee, infrastructure for making information accessible via the web. This involves
the use of a [web server](https://wordpress.org/support/article/glossary/#web-server)(
including web server software such as [Apache](https://codex.wordpress.org/Glossary#Apache)),
and may involve one or more related technologies, such as [FTP](https://codex.wordpress.org/Glossary#FTP),
[PHP](https://codex.wordpress.org/Glossary#PHP), [MySQL](https://codex.wordpress.org/Glossary#MySQL)
or [MariaDB](https://codex.wordpress.org/Glossary#MariaDB), and operating system
software such as [Linux](https://codex.wordpress.org/Glossary#Linux) or [Unix](https://codex.wordpress.org/Glossary#Unix).
* Related articles: [Hosting WordPress](https://wordpress.org/about/requirements/)
## .htaccess
A **.htaccess** file is a granular configuration file for the [Apache](https://codex.wordpress.org/Glossary#Apache)
[web server](https://codex.wordpress.org/Glossary#Web_server) software, used to
set or alter the server’s configuration settings for the directory in which it is
present, and/or its child directories.
WordPress uses an _.htaccess_ file in conjunction with the [mod_rewrite](https://codex.wordpress.org/Glossary#mod_rewrite)
[Apache](https://codex.wordpress.org/Glossary#Apache) module to produce [permalinks](https://codex.wordpress.org/Glossary#Permalink).
Note that _.htaccess_ is a _hidden file_ in [Unix](https://codex.wordpress.org/Glossary#Unix)/
[Linux](https://codex.wordpress.org/Glossary#Linux) (as dictated by the preceding
period ‘.’), meaning it may not be visible using the default settings of some [FTP clients](https://codex.wordpress.org/FTP_Clients).

## HTML
**HTML**, or **Hypertext Markup Language**, is a markup language used to describe
the semantic content of web pages. It is usually used with [CSS](https://codex.wordpress.org/Glossary#CSS)
and/or [JavaScript](https://codex.wordpress.org/Glossary#JavaScript). WordPress
renders web pages to conform to the HTML5 standard. The standard is set by the World
Wide Web Consortium ([W3C](http://www.w3.org)).
## Dirección IP
An **IP address** is a unique number (e.g. _70.84.29.148_) assigned to a computer(
or other internet-capable information appliance, such as a network printer) to enable
it to communicate with other devices using the _Internet Protocol_. It is a computer’s
identity on the internet, and every computer connected to the internet is assigned
at least one — although the methods of assigning these addresses, and the permanence
and duration of their assignment, differ according to the use of the computer and
the circumstances of its internet use.
Every [web server](https://codex.wordpress.org/Glossary#Web_server) is assigned
an IP address as well, but often times [hosting providers](https://codex.wordpress.org/Glossary#Hosting_provider)
will assign multiple IP addresses to one computer, in the event that multiple web
sites reside on the same physical server. This is the case with most inexpensive‘
managed’ or ‘group’ hosting packages.
[Domain names](https://codex.wordpress.org/Glossary#Domain_name) were created to
provide an easier means of accessing internet resources than IP addresses, which
are cumbersome to type and difficult to remember. Every domain name has at least
one corresponding IP address, but only a small number of IP addresses have a domain
name associated with them, since only computers that are servers require domain
names. The domain name system ([DNS](https://codex.wordpress.org/Glossary#DNS))
is what maps domain names to IP addresses.
* External links: [IP address](http://en.wikipedia.org/wiki/IP_address) (Wikipedia)
## IDE
Acronym for Integrated Development Environment. Is an application that provides
several tools for software development. An **IDE** usually includes:
* source code editor, which is similar to a [Text Editor](https://wordpress.org/support/article/glossary/#text-editor)
* debugger, in the case of WordPress, useful debuggers are those for [PHP](https://codex.wordpress.org/Glossary#PHP)
and [Javascript](https://codex.wordpress.org/Glossary#Javascript) code
* automated builder
Some examples of IDEs
* [Aptana Studio](http://www.aptana.com/) (Cross platform, Freeware)
* [Codelobster](http://www.codelobster.com/) (Windows only, Freeware)
* [Eclipse](http://www.eclipse.org/) (Cross platform, Freeware)
* [NetBeans](http://netbeans.org/features/php/) (Cross platform, Freeware)
## ISAPI
**ISAPI** (Internet Server Application Programming Interface) is a set of programming
standards designed to allow programmers to quickly and easily develop efficient
Web-based applications. Developed by Process Software and Microsoft Corporation,
_ISAPI_ is intended to replace [CGI](https://codex.wordpress.org/Glossary#CGI) programs.
* External links: [ISAPI at Wikipedia](http://en.wikipedia.org/wiki/ISAPI)
## JavaScript
**JavaScript** is a programming language that WordPress uses to make certain processing
occur in your web browser when it is inconvenient or impossible for the server to
do that processing. For example, when you reply to a comment in a WordPress blog,
WordPress uses JavaScript to move the comment form inside the comment you are replying
to.

## Linux
**Linux** is an [open source](http://en.wikipedia.org/wiki/Open_source) computer
operating system, created by Linus Torvalds, similar in style to [Unix](https://codex.wordpress.org/Glossary#Unix).
It is popular in [web server](https://codex.wordpress.org/Glossary#Web_server) and
other high-performance computing environments, and has recently begun to gain popularity
in workstation environments as well.
* External links: [Linux at Shortopedia](http://www.shortopedia.com/L/I/Linux)
## Mac OS X
**[Mac OS X](http://www.apple.com/macosx/)** is an operating system specifically
for modern Macintosh computers. The operating system was commercially released in
2001. It consists of two main parts: Darwin, an open source [Unix](https://codex.wordpress.org/Glossary#Unix)-
like environment which is based on the BSD source tree and the Mach microkernel,
adapted and further developed by Apple Computer with involvement from independent
developers; and a proprietary GUI named Aqua, developed by Apple.

## MariaDB
MariaDB is a fork of the [MySQL](https://codex.wordpress.org/Glossary#MySQL) relational
database system developed by most of the original developers of MySQL. It works
equally well with WordPress.
## Menú
**Menus** are lists of links to pages and posts that appear on WordPress websites.
## Meta
**Meta** has several meanings, but generally means **information about**. In WordPress,
_meta_ usually refers to **administrative** type information. As described in [Meta Tags in WordPress](https://codex.wordpress.org/Meta_Tags_in_WordPress),
_meta_ is the [HTML](https://codex.wordpress.org/Glossary#HTML) tag used to describe
and define a web page to the outside world (search engines). In the article [Post Meta Data](https://codex.wordpress.org/Post_Meta_Data_Section),
_meta_ refers to information associated with each **post**, such as the author’s
name and the date posted. [Meta Rules](https://codex.wordpress.org/Codex:Guidelines#Meta_Rules)
define the general protocol to follow in using the Codex. Also, many WordPress based
sites offer a _Meta_ section, usually found in the sidebar, with links to login
or register at that site. Finally, _Meta_ is a [MediaWiki](http://www.mediawiki.org)
[namespace](http://meta.wikimedia.org/wiki/Namespace) that refers to administrative
functions within Codex.
* External links: [Wikipedia’s Article on Meta](http://en.wikipedia.org/wiki/Meta-)
## Microformatos
**Microformats** provide a way for programs to read certain information in web pages
without making the pages look any different to humans. They add semantics to the
generic HTML markup in order for these programs to understand the meaning of specific
parts of a web page content which is better recognized by humans. For example, a
web page displaying a user’s profile could use microformats to make it easy for
a program to extract the user’s contact information so that it can be added to an
address book in a single operation. In WordPress, some [themes](https://codex.wordpress.org/Glossary#theme)
and [plugins](https://codex.wordpress.org/Glossary#plugin) support some microformats.

## MIME
**MIME** stands for **Multipurpose Internet Mail Extension** and is an Internet
standard that extends the format of email to support:
* Text in character sets other than ASCII
* Non-text attachments
* Message bodies with multiple parts
* Header information in non-ASCII character sets
MIME’s use, however, has grown beyond describing the content of email and now is
often used to describe content type in general including for the web and as a storage
for rich content in some commercial products.

## Moblogging
**Moblogging** is the act of posting to one’s [blog](https://codex.wordpress.org/Glossary#Blog)
via a mobile device, e.g. mobile phone, smartphone or tablet. It is pronounced as
_mōbə-logging_ or _mōb-logging_, or sometimes as _mŏb-logging_ in reference to _smart
mobs_.

**mod_rewrite** is an extension module of the [Apache](https://codex.wordpress.org/Glossary#Apache)
[web server](https://codex.wordpress.org/Glossary#Web_server) software which allows
for «rewriting» of [URLs](http://en.wikipedia.org/wiki/Url) on-the-fly. Rewrite
_rules_ use [regular expressions](http://en.wikipedia.org/wiki/Regular_expression)
to parse the requested URL from the client, translate it into a different URL, and
serve the content of this new URL under the original URL or pointing the client
to make the new URL request.
WordPress uses _mod\_rewrite_ for its [permalink](https://codex.wordpress.org/Glossary#Permalink)
structure, and also for [multisite](https://codex.wordpress.org/Glossary#Multisite)
networks, which are both optional functionality.

## Multisitio
**Multisite** is a feature of [WordPress 3.0](https://codex.wordpress.org/Version_3.0)
and later versions that allows multiple virtual [sites](https://codex.wordpress.org/Glossary#Site)
to share a single WordPress installation. When the multisite feature is activated,
the original WordPress site can be converted to support a [network](https://codex.wordpress.org/Glossary#Network)
of sites.

## MySQL
**MySQL** is a popular [open source](http://en.wikipedia.org/wiki/Open_source) SQL(
Structured Query Language) database implementation, available for many platforms,
including Windows, [Unix](https://codex.wordpress.org/Glossary#Unix)/[Linux](https://codex.wordpress.org/Glossary#Linux)
and [Mac OS X](https://codex.wordpress.org/Glossary#Mac_OS_X).
WordPress requires a MySQL database to store all [blog](https://codex.wordpress.org/Glossary#Blog)
information, including [posts](https://codex.wordpress.org/Glossary#Post), [comments](https://codex.wordpress.org/Glossary#Comments),
[metadata](https://codex.wordpress.org/Glossary#Meta), and other information.
WordPress also works with MySQL-compatible databases such as [MariaDB](https://codex.wordpress.org/Glossary#MariaDB)
and Percona Server.

## Navegación
Navigation is the term used to describe text on a page that, when selected, redirects
you to a corresponding page elsewhere on the website. Navigation may sometimes be
referred to as the menu, links and hyperlinks.
## Red
In the WordPress user interface, a **network** is a collection of separate [sites](https://codex.wordpress.org/Glossary#Site)
created in a single WordPress installation by the [multisite](https://codex.wordpress.org/Glossary#Multisite)
feature. The sites in a WordPress network are not interconnected like the things
in other kinds of networks. They are very like the separate blogs at WordPress.com.
In WordPress code the network is known as the _site_ and the sites are known as
_blogs_.
* Related articles: [Create A Network](https://codex.wordpress.org/Create_A_Network)
## Lector de noticias
A **news aggregator** or **news (feed) reader** is a computer program which tracks
syndicated information [feeds](https://codex.wordpress.org/Glossary#Feed), via [RSS](https://codex.wordpress.org/Glossary#RSS),
[RDF](https://codex.wordpress.org/Glossary#RDF), or [Atom](https://codex.wordpress.org/Glossary#Atom).
Most news aggregators allow one to ‘subscribe’ to a feed, and automatically keep
track of the articles one has read, similar to an email client tracking read emails.
Many [blogs](https://codex.wordpress.org/Glossary#Blog) make their content available
in [feed](https://codex.wordpress.org/Glossary#Feed) form for the convenience of
readers using news aggregators. WordPress can generate feeds in [RSS](https://codex.wordpress.org/Glossary#RSS)
and/or [Atom](https://codex.wordpress.org/Glossary#Atom) formats.
* External links: [News aggregator at Wikipedia](http://en.wikipedia.org/wiki/News_aggregator)
## Nonce
**Nonce** is used for security purposes to protect against unexpected or duplicate
requests that could cause undesired permanent or irreversible changes to the web
site and particularly to its database. Specifically, a nonce is an one-time token
generated by a [web site](https://codex.wordpress.org/Glossary#Web_site) to identify
future requests to that web site. When a request is submitted, the web site verifies
if a previously generated nonce expected for this particular kind of request was
sent along and decides whether the request can be safely processed, or a notice
of failure should be returned. This could prevent unwanted repeated, expired or
malicious requests from being processed.
Nonce is usually included in a hidden HTML form field or as a part of an URL and
therefore sent with a request by submitting a form field or visiting a link. If
a request is not verified, the web site could generate a new nonce in its response
and prompt the user to intentionally confirm the repetition of the request. In WordPress,
the response message is _«Are you sure you want to do this?»_ by default.
* Related articles: [WordPress Nonces](https://codex.wordpress.org/WordPress_Nonces)
## Código abierto
**Open source** is simply programming code that can be read, viewed, modified, and
distributed, by anyone who desires. WordPress is distributed under an _open source_
[GNU General Public License (GPL)](http://www.gnu.org/copyleft/gpl.html).
* Related articles: [GPL](https://codex.wordpress.org/GPL), [License](https://codex.wordpress.org/License)

[Source Code at Wikipedia](http://en.wikipedia.org/wiki/Source_code)
## Opciones
**Options** are pieces of data that WordPress uses to store various preferences
and configuration settings. By using the [Options API](https://codex.wordpress.org/Options_API)
that is a simple and standardized way of storing data in the database, options can
be [added](https://codex.wordpress.org/Function_Reference/add_option), [changed](https://codex.wordpress.org/Function_Reference/update_option),
[removed](https://codex.wordpress.org/Function_Reference/delete_option), and [retrieved](https://codex.wordpress.org/Function_Reference/get_option),
from the [wp_options table](https://codex.wordpress.org/Database_Description#Table:_wp_options).

## Compresión de salida
**Output Compression** is the removal of white spaces, carriage returns, new lines
and tabs from your HTML document. This reduces the file size of the HTML document
without changing the functionality.
* Related articles: [Output Compression](https://codex.wordpress.org/Output_Compression)
## Página
A **Page** is often used to present «static» information about yourself or your
site. A good example of a Page is information you would place on an About Page.
A Page should not be confused with the time-oriented objects called [posts](https://codex.wordpress.org/Glossary#Post).
Pages are typically «timeless» in nature and live «outside» your blog.
The word «page» has long been used to describe any HTML document on the web. In
WordPress, however, «Page» refers to a very specific feature first introduced in
WordPress version 1.5.

## Perl
**Perl** is an acronym for **Practical Extraction and Report Language**, but it’s
most commonly spelled as a proper name. It’s a very popular and powerful scripting
language used for web applications, although its use is being largely replaced by
[PHP](https://codex.wordpress.org/Glossary#PHP) in the mainstream. One of its strengths
lies in its speedy and effective use of [regular expressions](http://en.wikipedia.org/wiki/Regular_expression).
Its unofficial motto is, «There’s More Than One Way To Do It,» or «TMTOWTDI,» owing
to the extreme flexibility of the syntax.
WordPress does not use Perl, and it is therefore not required.
## Enlace permanente
A **permalink** is a [URL](http://en.wikipedia.org/wiki/Url) at which a resource
or article will be permanently stored. Many pages driven by [Content Management Systems](https://codex.wordpress.org/Glossary#Content_Management_System)
contain excerpts of content which is frequently rotated, making linking to bits
of information within them a game of chance. Permalinks allow users to bookmark
full articles at a [URL](http://en.wikipedia.org/wiki/Url) they know will never
change, and will always present the same content.
Permalinks are optional in WordPress, but are highly recommended as they greatly
increase the cleanliness of [URL](http://en.wikipedia.org/wiki/Url). WordPress uses
the [Apache](https://codex.wordpress.org/Glossary#Apache) module _[mod\_rewrite](https://codex.wordpress.org/Glossary#mod_rewrite)_
to implement its permalink system.
* Related articles: [Using Permalinks](https://codex.wordpress.org/Using_Permalinks)

## Permisos
**Permissions** are security settings restricting or allowing users to perform certain
functions. In the case of files on [Unix](https://codex.wordpress.org/Glossary#Unix)
or [Linux](https://codex.wordpress.org/Glossary#Linux) systems, there are three
types of permissions: _read_, _write_, and _execute_. In the case of [MySQL](https://codex.wordpress.org/Glossary#MySQL)
or [MariaDB](https://codex.wordpress.org/Glossary#MariaDB) databases, there are
many more: `SELECT`, `INSERT`, `UPDATE`, `DELETE`, etc. — although MySQL/MariaDB
refer to them as _privileges_.
* Related articles: [Changing File Permissions](https://codex.wordpress.org/Changing_File_Permissions)
## PHP
**PHP** is a recursive acronym for **PHP: Hypertext Preprocessor**. It is a popular
server-side scripting language designed specifically for integration with [HTML](https://codex.wordpress.org/Glossary#HTML),
and is used (often in conjunction with [MySQL](https://codex.wordpress.org/Glossary#MySQL)
or [MariaDB](https://codex.wordpress.org/Glossary#MariaDB)) in [Content Management Systems](https://codex.wordpress.org/Glossary#Content_Management_System)
and other web applications. It is available on many platforms, including Windows,
[Unix](https://codex.wordpress.org/Glossary#Unix)/[Linux](https://codex.wordpress.org/Glossary#Linux)
and [Mac OS X](https://codex.wordpress.org/Glossary#Mac_OS_X), and is [open source](http://en.wikipedia.org/wiki/Open_source)
software.
WordPress is written using PHP and requires it for operation.

[Matthew Mullenweg](https://codex.wordpress.org/User:Matt), [PHP at OnLAMP](http://www.onlamp.com/php/)
## phpMyAdmin
**phpMyAdmin** is a popular, powerful web-based interface for administering [MySQL](https://codex.wordpress.org/Glossary#MySQL)
or [MariaDB](https://codex.wordpress.org/Glossary#MariaDB) databases. It is [open source](http://en.wikipedia.org/wiki/Open_source),
written in [PHP](https://codex.wordpress.org/Glossary#PHP), and is among the better
tools available for working with [MySQL](https://codex.wordpress.org/Glossary#MySQL)
or [MariaDB](https://codex.wordpress.org/Glossary#MariaDB) databases.
* Related articles: [phpMyAdmin](https://codex.wordpress.org/phpMyAdmin)

## Ping
Within the WordPress interface, «ping» is sometimes used to refer to [Pingbacks](https://codex.wordpress.org/Glossary#Pingback)
and [Trackbacks](https://codex.wordpress.org/Glossary#Trackback).
In general computer terms, «ping» is a common utility used in a TCP/IP environment
to determine if a given [IP Address](https://codex.wordpress.org/Glossary#IP_address)
exists or is reachable. Typically, Ping is used to diagnose a network connection
problem. Many times you will be asked, «Can you ping that address?». That means,
does the Ping utility return a success message trying to reach the «problem» [IP Address](https://codex.wordpress.org/Glossary#IP_address)?
* External links: [Ping at Wikipedia](http://en.wikipedia.org/wiki/Ping)
## Pingback
**Pingback** lets you notify the author of an article if you link to his article(
article on a blog, of course). If the links you include in an article you write
on a blog lead to a blog which is pingback-enabled, then the author of that blog
gets a notification in the form of a pingback that you linked to his article.
If you’re feeling _really_ geeky you may want to check out the [Pingback technical specification](http://hixie.ch/specs/pingback/pingback)
or [Otto’s «How Pingbacks Work» explanation](http://lists.automattic.com/pipermail/wp-hackers/2009-September/027425.html).

## Plugin
A **Plugin** is a group of PHP functions that can extend the functionality present
in a standard WordPress weblog. These functions may all be defined in one php file,
or may be spread among more than one file. Usually, a plugin is a PHP file that
can be uploaded to the «wp-content/plugins» directory on your webserver, where you
have installed WordPress. Once you have uploaded the plugin file, you should be
able to «turn it on» or Enable it from the «Plugins» page in the administration
interface of your weblog. The WordPress source code contains hooks that can be used
by plugins.

* Related articles: [Plugins](https://codex.wordpress.org/Plugins)
## Puerto
Within the context of the WordPress community, a **port** is a bit of code that
has been rewritten to be compatible with WordPress. For example, if someone wrote
a plugin for MoveableType, WordPress users may want to find a port of that plugin
for WordPress. Port can also be used as a verb: to rewrite a piece of software for
a different platform/language.
* External links: [Porting at Wikipedia](http://en.wikipedia.org/wiki/Porting)
## Entrada
Also known as “articles” and sometimes incorrectly referred to as “blogs”. In WordPress,“
posts” are articles that you write to populate your blog.
## Slug de la entrada
A few lowercase words separated by dashes, describing a post and usually derived
from the post title to create a user-friendly (that is, readable and without confusing
characters) [permalink](https://codex.wordpress.org/Permalinks). Post slug substitutes
the «%posttitle%» placeholder in a [custom permalink structure](https://codex.wordpress.org/Permalinks#Choosing_your_permalink_structure).
Post slug should not be changed and is especially useful if the post title tends
to be long or changes frequently.
## Estado de la entrada
The status of a post, as set in the [Administration Panel](https://codex.wordpress.org/Administration_Panels),
[Write Post SubPanel](https://codex.wordpress.org/Write_Post_SubPanel) is either:**
Published** (viewable by everyone), **Draft** (incomplete post viewable by anyone
with proper [user level](https://codex.wordpress.org/User_Levels)), or **Private**(
viewable only to WordPress users at Administrator level).
* Related articles: [Post Status](https://codex.wordpress.org/Post_Status)
## Tipo de contenido
Post type refers to the various structured data that is maintained in the WordPress
posts table. Native (or built-in) registered post types are **post**, **page**, **
attachment**, **revision**, and **nav-menu-item**. Custom post types are also supported
in WordPress and can be defined with [register_post_type()](https://codex.wordpress.org/Function_Reference/register_post_type).
Custom post types allow users to easily create and manage such things as portfolios,
projects, video libraries, podcasts, quotes, chats, and whatever a user or developer
can imagine.
* Related articles: [Post Types](https://codex.wordpress.org/Post_Types)
## Consulta
The process behind the scenes. See below. 🙂

[WP User Query](https://codex.wordpress.org/Class_Reference/WP_User_Query)_
* See also: _[query string](https://codex.wordpress.org/Glossary#Query_String)_,_
[query variable](https://codex.wordpress.org/Glossary#Query_Variable)_
## Cadena de consulta
A sequence of codes in a [Uniform Resource Identifier (URI)](http://en.wikipedia.org/wiki/Uniform_Resource_Identifier)
that a web page uses to determine what dynamic data to display. The query string
in a [URI](http://en.wikipedia.org/wiki/Uniform_Resource_Identifier) comes after
an initial question mark, and may contain several parameters separated by ampersands.
WordPress uses query strings to indicate criteria to search for specific posts or
sets of posts in the database. The use of query strings is generally believed to
impede the indexing of dynamic pages by search engines. For this reason, it is often
desirable to use a method such as [mod_rewrite](https://codex.wordpress.org/Glossary#mod_rewrite)
to reduce exposure of query strings to search engines and other site visitors.
## Variable de consulta
A variable passed through the [query string](https://codex.wordpress.org/Glossary#Query_string).
For example, in the query string _?category\_name=tech&feed=atom_, there are two
query variables: _category\_name_ with a value of «tech», and _feed_ with a value
of «atom».
## Etiqueta rápida
A **Quicktag** is a shortcut, or one-click button, that inserts HTML code into your
posts. The (emphasis) and (stop emphasis) HTML tags are example of Quicktags.
Some Quicktags, such as , insert HTML comment code that is used
by plugins to replace text or perform certain actions.
[Back to the Top](https://codex.wordpress.org/Glossary#top)
## RDF
Resource Description Framework. A language used to describe the locations of resources
on the web. WordPress can produce output in RDF format that describes the locations
of posts. Like RSS, RDF is used for content syndication.
## Ruta relativa
A **relative path** is the location of a file in relation to the current working
directory and does not begin with a slash (/). This is different from an [absolute path](https://codex.wordpress.org/Glossary#Absolute_Path)
which gives an exact location.
* See also: [Absolute Path](https://codex.wordpress.org/Glossary#Absolute_Path)
* External links: [Path_Computing at Wikipedia](http://en.wikipedia.org/wiki/Path_(computing))
## URI relativa
A relative URI (sometimes called a **relative link**) is a partial URI that is interpreted(
resolved) relative to a **base URI**.
On the World Wide Web, relative URIs come in two forms:
A **relative URI with an absolute path** is interpreted relative to the domain root:
```wp-block-preformatted
/images/icecream.jpg → http://domain.example/images/icecream.jpg
```
A **relative URI with a relative path** is interpreted relative to the URL of the
current document. E.g., on the web page _http://domain.example/icecream/chocolate.
html_,
```wp-block-preformatted
strawberry.html → http://domain.example/icecream/strawberry.html
```
[Wikipedia: URI Resolution](http://en.wikipedia.org/wiki/Uniform_Resource_Identifier#URI_resolution)
## Conjunto de registros
**Recordset** refers to the group of records or result returned from a database
query.
* See also [MySQL](https://codex.wordpress.org/Glossary#MySQL), [wpdb](https://codex.wordpress.org/Class_Reference/wpdb)
database class
## RSS
«_Really Simple Syndication_«: a format for syndicating many types of content, including
blog entries, torrent files, video clips on news-like sites; specifically frequently
updated content on a Web site, and is also known as a type of «feed» or «aggregator».
An RSS feed can contain a summary of content or the full text, and makes it easier
for people to keep up to date with sites they like in an automated manner (much
like e-mail).
The content of the feed can be read by using software called an [RSS or Feed reader](https://codex.wordpress.org/Glossary#News_reader).
Feed readers display hyperlinks, and include other metadata (information about information)
that helps people decide whether they want to read more, follow a link, or move
on.
The original intent of RSS is to make information come to you (via the feed reader)
instead of you going out to look for it (via the Web).
Programs called news aggregators permit users to view many feeds at once, providing‘
push’ content constantly. See [Category:Feeds](https://codex.wordpress.org/Category:Feeds)
for Codex resources about bringing RSS feeds into WordPress. See also [RDF](https://codex.wordpress.org/Glossary#RDF)

## RTL
A written language is [Right-to-left](http://en.wikipedia.org/wiki/Right-to-left)
when its script flows from the right side of the page to the left.
* Related articles: [Right-to-Left Language Support](https://codex.wordpress.org/Right-to-Left_Language_Support)
## Robots.txt
Web Robots are programs which traverse the Web automatically. They are also called
Web Wanderers, Web Crawlers, and Spiders. Search Engines are the main Web Robots.
Some Web Robots look for a file named **robots.txt** on your [web server](https://codex.wordpress.org/Glossary#Web_server)
to see what and where they should look for content and files on your web server.
Some Web Robots ignore this file.

[The Web Robots Page](http://www.robotstxt.org/wc/robots.html)
## Perfil
A **role** gives users permission to perform a group of tasks. When a user logs
in and is authenticated, the user’s role determines which [capabilities](https://codex.wordpress.org/Glossary#Capabilities)
the user has, and each capability is permission to perform one or more types of
task. All users with the same role normally have the same capabilities. For example,
users who have the Author role usually have permission to edit their own posts,
but not permission to edit other users’ posts. WordPress comes with six roles and
over fifty capabilities in its role-based access system. Plugins can modify the
system.

## Pantalla
In WordPress a **screen** is a web page used for managing part of a weblog ([site](https://codex.wordpress.org/Glossary#Site))
or [network](https://codex.wordpress.org/Glossary#Network). The term ‘screen’ is
used to avoid confusion with ‘[page](https://codex.wordpress.org/Glossary#Page)‘,
which has a specific and different meaning in WordPress. For example, the web page
used to manage posts is known as the [Posts Screen](https://codex.wordpress.org/Posts_Screen).
* Related article: [Class_Reference/WP_Screen](https://codex.wordpress.org/Class_Reference/WP_Screen)
## Shell
A **shell** is a program which interacts directly with an operating system such
as MS-DOS, [Unix](https://codex.wordpress.org/Glossary#Unix)/[Linux](https://codex.wordpress.org/Glossary#Linux),
[Mac OS X](https://codex.wordpress.org/Glossary#Mac_OS_X), or others — but it is
most commonly associated with [Unices](https://codex.wordpress.org/Glossary#Unix).
It is often referred to as a ‘console’ or ‘command line’, because it is controlled
using typed commands rather than mouse or graphical interface input.
Most often, when interacting with a remote computer (as one would when configuring
WordPress), an additional «faux» shell is involved called [SSH](https://codex.wordpress.org/Glossary#SSH).
Some popular shell programs are:
* [Bash](http://www.gnu.org/software/bash/bash.html) (Bourne Again Shell)
* [Tcsh](http://tcsh.org/) (an expanded C Shell)
* [Zsh](http://www.zsh.org/)
## Shortcode
A [Shortcode](https://codex.wordpress.org/Shortcode) is a technique for embedding
a snippet of [PHP](https://codex.wordpress.org/Glossary#PHP) code into the body
of a page or other content item.
## Barra lateral
A **sidebar** is a vertical column provided by a [theme](https://codex.wordpress.org/Glossary#Theme)
for displaying information other than the main [content](https://codex.wordpress.org/Glossary#Content)
of the web page. Themes usually provide at least one sidebar at the left or right
of the content. Sidebars usually contain [widgets](https://codex.wordpress.org/Glossary#Widget)
that an administrator of the site can customize.
In a theme, sidebars are generated by a [template](https://codex.wordpress.org/Glossary#Template)
file, typically named _sidebar.php_.
* See also: [Footer area](https://codex.wordpress.org/Glossary#Footer_area)

[Template Hierarchy](https://codex.wordpress.org/Template_Hierarchy)
## Sitio
In the WordPress user interface, a **site** can simply be the website created by
WordPress, or it can be a virtual website created as part of a [network](https://codex.wordpress.org/Glossary#Network)
by the [multisite](https://codex.wordpress.org/Glossary#Multisite) feature. A site
in a network is virtual in the sense that it does not have its own directory on
the server, although it has its own URL and it might have its own domain name.
In WordPress code the site is the website created by WordPress. If multisite is
in use, then the site is the network website and each virtual website is known as
a _blog_.
* Related article: [Create A Network](https://codex.wordpress.org/Create_A_Network)
## Slug
A **slug** is a few words that describe a post or a page. Slugs are usually a URL
friendly version of the post title (which has been automatically generated by WordPress),
but a slug can be anything you like. Slugs are meant to be used with [permalinks](https://codex.wordpress.org/Glossary#Permalink)
as they help describe what the content at the URL is.
Example post permalink: _[https://wordpress.org/development/2006/06/wordpress-203/](https://wordpress.org/development/2006/06/wordpress-203/)_
The slug for that post is «wordpress-203».
Slugs are also used for post types, categories, tags, etc. Like post and page slugs,
this is usually for creating URL friendly versions of these items.
## Smileys
[⌊Wink Icon⌉⌊Wink Icon⌉[
Smileys (also called Smilies or Emoticons) are stylized representations of a human
face, usually displayed as yellow buttons with two dots for the eyes, and a half
mouth. Smileys are often used in WordPress Plugins. By default, WordPress automatically
converts text smileys to graphic images. When you type 😉 in your post you see when
you preview or publish your post.

## Spam
Once upon a time, [SPAM](http://www.hormel.com) was an animal by-product that came
in a can and was fodder for many Monty Python sketches, but since the world-wide
adoption of the internet as an integral part of daily life, Spam has become synonymous
with what is wrong with the internet. Spam, in general terms, is an email or other
forms of unsolicited advertising. Spam is very easy to spread throughout the internet,
and works on the principle that if you send out thousands, or hundreds of thousands
of unsolicited advertisements, scams, or other questionable methods of making money,
that you only need a very small percentage of people to be fooled and you will make
lots of money.
Common spam these days comes from online gambling sites and those trying to sell
drugs for «male enhancement.» Lately, web logs, or blogs, as we call them, have
been targeted by spammers to try to increase their site ratings in the search engines.
Spammers use various methods to distribute their electronic junk mail, and employ
bots, or computer programs to quickly and easily send email or comments to millions
of addresses and [IPs](https://codex.wordpress.org/Glossary#IP_address) all over
the world.
Spammers can be difficult to track down as they often hijack peoples’ email and
[IP](https://codex.wordpress.org/Glossary#IP_address) addresses. When this happens,
it may appear a friend sent you the spam, but in fact, the spammer’s [bot](http://en.wikipedia.org/wiki/Internet_bot)
grabbed your friend’s email address and used it to hide the true source of the spam.
WordPress [developers](https://codex.wordpress.org/Glossary#Developer) and community
members are constantly working on more and better ways to combat these annoying **
spammers** as they clog the internet with their garbage. You can help by offering
your talents, ideas, suggestions, or just by being vigilant and installing any of
the [currently-available spam combating tools](https://codex.wordpress.org/Combating_Comment_Spam).

## SSH
**SSH** stands for Secure Shell. It is a communication protocol for connecting to
remote computers over TCP/IP. Various authentication methods can be used which make
SSH more secure than [Telnet](https://codex.wordpress.org/Glossary#Telnet).
## SSL
**SSL** stands for Secure Sockets Layer and is the predecessor to Transport Layer
Security. These are cryptographic protocols for secure communications across an
unsecured network like the Internet.
* External links: [SSL at Wikipedia](http://en.wikipedia.org/wiki/Secure_Sockets_Layer)
## Estadísticas
**Stats** are a record showing how many views and visitors a WordPress blog or website
gets during a set period of time. Stats also show where in the world your viewers
are.
## Cadena
In computer science a string is any finite sequence of characters (i.e., letters,
numerals, symbols and punctuation marks). Typically, programmers must enclose strings
in quotation marks for the data to be recognized as a string and not a number or
variable name.
* External links: [String at Wikipedia](http://en.wikipedia.org/wiki/String_(computer_science))
## Etiquetas de estructura
These tags are used to customize WordPress permalinks. Structure tags are: %year%,%
day%, %hour%, %minute%, %second%, %post_id%, %postname%, %category% and %author%.
End permalink structure with either %post_id% or %postname%, so that each permalink
points to an individual post.

## Subversion
[Subversion](http://subversion.tigris.org/) is an [open-source](https://codex.wordpress.org/Glossary#Open_Source)
[version control](http://en.wikipedia.org/wiki/Revision_control) software tool used
by the [WordPress Developers](https://codex.wordpress.org/Copyright_Holders) to
maintain and track the changes and updates to the various WordPress versions.

## SVC
**SVC** stands for Switched Virtual Circuit. An SVC is a virtual circuit that is
temporary turned on during a session of data transfer.
* External links: [Virtual circuit at Wikipedia](http://en.wikipedia.org/wiki/Virtual_circuit)
## Sindicación
See RSS: [Really Simple Syndication](https://codex.wordpress.org/Glossary#RSS)
[Back to the Top](https://codex.wordpress.org/Glossary#top)
## Etiqueta
A Tag is a keyword which describes all or part of a Post. Think of it like a [Category](https://codex.wordpress.org/Glossary#Category),
but smaller in scope. A Post may have several tags, many of which relate to it only
peripherally. Like Categories, Tags are usually linked to a page which shows all
Posts having the same Tag. Tags can be created on-the-fly by simply typing them
into the [Tag field](https://codex.wordpress.org/Writing_Posts#Post_Tags). By default,
tags can be assigned only to the _Post_ and custom [post types](https://codex.wordpress.org/Post_types).
Tags can also be displayed in [clouds](http://en.wikipedia.org/wiki/Tag_Cloud) which
show large numbers of Tags in various sizes, colors, etc. This allows for a sort
of total perspective on the blog, allowing people to see the sort of things your
blog is about most.
Many people confuse Tags and Categories, but the difference is easy: Categories
generally don’t change often, while your Tags usually change with every Post and
are closer to the topic of the Post.
## Descripción corta
A tagline is a catchy phrase that describes the character or the attributes of the
blog in a brief, concise manner. Think of it as the slogan, or catchline for a weblog.
## Documentación basada en tareas
Task based, or task oriented documentation is writing that takes you through a process/
task step-by-step; it is succinct, lacks jargon, is easily understood, and structured
entirely around performing specific tasks. In order to get to Z, you need to:
1. Step x
2. Step y
3. Step z
Keep in mind that people who need to know how to perform a task usually need answers
quick!
## Taxonomía
A **taxonomy** allows for the classification of things. In WordPress, there are
two built-in taxonomies, categories and tags. These taxonomies help further classify
posts and custom post types. Also, custom taxonomies can be defined.
* See also: [Category](https://codex.wordpress.org/Glossary#Category), [Tag](https://codex.wordpress.org/Glossary#Tag)

## Telnet
Telnet is a [communications protocol](http://en.wikipedia.org/wiki/Internet_protocol_suite)
used to establish a connection to another computer. _Telnet_ runs on top of [TCP](http://en.wikipedia.org/wiki/Transmission_Control_Protocol)/
[IP](http://en.wikipedia.org/wiki/Internet_Protocol) and is typically used in conjuction
with terminal emulation software to login to remote computers. Telnet is inherently
insecure and has largely been replaced by [SSH](https://codex.wordpress.org/Glossary#SSH)
* External links: [Telnet at Wikipedia](http://en.wikipedia.org/wiki/Telnet)
## Plantilla
In WordPress a **template** is a file that defines an area of the web pages generated
by a [theme](https://codex.wordpress.org/Glossary#Theme). For example, there is
typically a template for the header area at the top of the web pages, a template
for the [content](https://codex.wordpress.org/Glossary#Content), a template for
the [sidebars](https://codex.wordpress.org/Glossary#Sidebar), and so on. The templates
are like building blocks that make up the complete web page.
* Related articles: [Templates](https://codex.wordpress.org/Templates), [Stepping Into Templates](https://codex.wordpress.org/Stepping_Into_Templates),
[Template Hierarchy](https://codex.wordpress.org/Template_Hierarchy)
## Etiqueta de plantilla
In a WordPress Theme, [template tags](https://codex.wordpress.org/Template_Tags)
are used in template files to generate specific programming instructions. They are
used to display generated content and information on a WordPress site. Template
tags are short programming words, also known as functions, that tap into the WordPress
core for instructions. For example, the HTML title tag of a WordPress site may hold
the [bloginfo()](https://codex.wordpress.org/Function_Reference/bloginfo) template
tag that requests the site title, site tagline, and other site information set by
the template tag parameters. Using this in the title HTML tag allows the Theme to
be used on multiple sites and the information displayed will change easily with
each site.
Other template tags are more sophisticated, generating post content, queries, and
site data.

[Function Reference](https://codex.wordpress.org/Function_Reference), [Templates](https://codex.wordpress.org/Templates)
## Término
In WordPress, a **term** is a classification, group or subset of a [Taxonomy](https://codex.wordpress.org/Glossary#Taxonomy),
where the latter can be a [Category](https://codex.wordpress.org/Glossary#Category),
[Tag](https://codex.wordpress.org/Glossary#Tag) or Custom Taxonomy. By default,
terms have a title, a slug and a description. Hierarchical taxonomies like categories
can define a parent term.

## Editor de texto
A **text editor** is a program which edits files in _plain text_ format, as compared
to _binary_ format. Using a non-text based word processing program (e.g. using Microsoft
Word to edit [PHP](https://codex.wordpress.org/Glossary#PHP) scripts) can cause
major problems in your code. This is because non-text based word processing programs
insert extra formatting into text files, and can corrupt the files when they need
to be interpreted by the interpreter. An editor like Notepad does not insert any
extra formatting.
**Edit WordPress Files with a text only editor.**
Some examples of file formats which need to be edited as plain text:
* [HTML](https://codex.wordpress.org/Glossary#HTML) documents
* [PHP](https://codex.wordpress.org/Glossary#PHP) scripts
* [Perl](https://codex.wordpress.org/Glossary#Perl) scripts
* Rich Text Format documents
* [JavaScript](https://codex.wordpress.org/Glossary#JavaScript) scripts

Some examples of non-plain text formats that require special software for editing:
* Microsoft Word documents
* Microsoft Excel spreadsheets
* Images, such as JPEG, PNG, or GIF
Some examples of software which can edit text, but which are **NOT** regarded as
basic text editors and **NOT recommended** for use on WordPress files:
* Microsoft Word
* Microsoft Excel
* Adobe Photoshop
* Adobe Illustrator
* Adobe Dreamweaver
## Tema
A Theme is a collection of files that work together to produce a graphical front-
end interface with an underlying unifying design for a site. A WordPress Theme modifies
the way the site is displayed and designed, without modifying the underlying core
programming of WordPress. While some associate a WordPress Theme with «skinning»
your site with a design, a WordPress Theme contains programming code that influences
the design, changing it with each generated page view based upon the programming
with PHP, WordPress template tags, WordPress conditional tags, and CSS.

## Barra de herramientas
The **Toolbar** is an area of the screen just above that site that lists useful
admininstration screen links such as add a new post or edit your profile. The Toolbar
was added in [Version 3.1](https://codex.wordpress.org/Version_3.1) as [Admin Bar](https://codex.wordpress.org/Glossary#Admin_Bar)
and in [Version 3.3](https://codex.wordpress.org/Version_3.3) it was replaced by
the [Toolbar](https://codex.wordpress.org/Glossary#Toolbar). The toolbar can be
turned on/off from the [User Profile Screen](https://codex.wordpress.org/Users_Your_Profile_SubPanel).

## Trackback
Trackback helps you to notify another author that you wrote something related to
what he had written on his blog, even if you don’t have an explicit link to his
article. This improves the chances of the other author sitting up and noticing that
you gave him credit for something, or that you improved upon something he wrote,
or something similar. With pingback and trackback, blogs are interconnected. Think
of them as the equivalents of acknowledgements and references at the end of an academic
paper, or a chapter in a textbook.
* See also: [Pingback](https://codex.wordpress.org/Glossary#Pingback)
* Related articles: [Introduction to Blogging: Trackbacks](https://codex.wordpress.org/Introduction_to_Blogging#Trackbacks)
## Dato transitorio
A **Transient** is temporal data identified by a custom name, stored in the [web server](https://codex.wordpress.org/Glossary#Web_server)
database or memory for fast access. This temporal nature and use of fast memory
caching is their primary distinction from [Options](https://codex.wordpress.org/Glossary#Options).

## Tema Twenty Ten
Starting with [Version 3.0](https://codex.wordpress.org/Version_3.0), the [Twenty Ten theme](https://codex.wordpress.org/Glossary#Twenty_Ten_theme)
became the default (and fallback) theme. As described in [2010: A Theme Odyssey](https://wordpress.org/development/2009/12/2010-a-theme-odyssey/),
the Twenty Ten theme serves as a good example theme that includes new theme-based
features, and looks nice on a public site. Twenty Ten is a community-developed theme.
Up to [Version 2.9.2](https://codex.wordpress.org/Version_2.9.2), the default theme
was the Kubrick theme and was housed in the _wp-content/themes/default_ folder.
The Twenty Ten theme is housed in the _wp-content/themes/twentyten_ folder and was
the only theme in the WordPress distribution.

## Tema Twenty Eleven
Starting with [Version 3.2](https://codex.wordpress.org/Version_3.2), the [Twenty Eleven theme](https://codex.wordpress.org/Glossary#Twenty_Eleven_theme)
was the default (and fallback) theme. Twenty Eleven is a community-developed theme
that emphasizes [Post Formats](https://codex.wordpress.org/Post_Formats), random
theme header images, customizable layouts and colors, HTML 5 improvements, and adherence
to [WordPress coding standards](https://codex.wordpress.org/WordPress_Coding_Standards).
It was replaced as the default in [Version 3.5](https://codex.wordpress.org/Version_3.5)
by the [Twenty Twelve theme](https://codex.wordpress.org/Glossary#Twenty_Twelve_theme).

became the default (and fallback) theme.
It is clean, blog-focused, and designed for clarity. Twenty Fifteen’s simple, straightforward
typography is readable on a wide variety of screen sizes, and suitable for multiple
languages. It was designed using a mobile-first approach, meaning content takes
center-stage, regardless of whether the site is accessed by smartphone, tablet,
laptop, or desktop computer.

## Unicode
A widely supported and preferred character encoding system.
For a computer to display letters (or any text characters), it needs to enumerate
them – create an index of characters it knows how to display. These indexes are
known as character sets. This is invaluable for users hosting [WordPress in a non-English language](https://codex.wordpress.org/Localization).
The most widely used collections of these character sets are the iso-8859 with [iso-8859-1](http://en.wikipedia.org/wiki/ISO_8859-1)
and [iso-8859-15](http://en.wikipedia.org/wiki/ISO_8859-15) (which contains the
euro sign and some characters used in Dutch, French, Czech and Slovak) being the
most common; they are also known as Latin1 and Latin9. These character sets use
8 bits (a single byte) for each character, allowing for 255 different characters(
256, counting null). However, when considering that Latin-based languages aren’t
the only ones in the world (think Japanese or Hebrew), 255 characters aren’t nearly
enough.
There is a wide index of characters known as [Unicode](http://en.wikipedia.org/wiki/Unicode).
Unicode has so many characters that sometimes more than 16 bits (2 bytes!) are required
to represent them. Furthermore, the first 127 characters of Unicode are the same
as the first 127 of the most widely used character set – iso-8859-1. For this purpose,
UTF, the Unicode Translation Format, was created. UTF uses different numbers of
bits for characters, and allows for the entire range of Unicode to be used. What
you should probably know is:
* UTF-8 is an 8-bit-minimum type of UTF. There are also UTF-16 and UTF-32.
* If your document is in a Latin-based encoding, you probably don’t need to change
anything about it for it to be UTF.
* A single UTF document can be in various languages with no need to switch encodings
halfway through.
* External links: [Joel Spolsky on Unicode](http://www.joelonsoftware.com/articles/Unicode.html)
## Unix
**Unix**, or **UNIX**, is a computer operating system developed at AT&T’s Bell Laboratories
starting back in 1969. Initially designed with the objective of creating an OS written
in a high level language rather than assembly, a majority of [web servers](https://codex.wordpress.org/Glossary#Web_server)
currently run on different «flavors» of this high-performance OS, or on [Linux](https://codex.wordpress.org/Glossary#Linux),
developed as a Unix-like operating system.
* See also: [UNIX Shell Skills](https://codex.wordpress.org/UNIX_Shell_Skills),
[Mac OS X](https://codex.wordpress.org/Glossary#Mac_OS_X)
## Tiempo Unix
**Unix Time**, or a **timestamp**, is a method of tracking time by determining the
approximate number of seconds from a particular event. That event is called an Epoch.
Since this time format is only off by a few seconds each century, it is usually
considered good enough for most applications.
Unix time is (currently) a ten digit number, and looks like this: 1229362315. WordPress
often uses a Unix timestamp internally to track time. The human readable times and
dates you see are converted from Unix Time or from a MySQL/MariaDB DATETIME field.
* External Links: [Unix Time at Wikipedia](http://en.wikipedia.org/wiki/Unix_time),
[DATETIME](http://dev.mysql.com/doc/refman/en/datetime.htmllMySQL), [MariaDB DATETIME](https://mariadb.com/kb/en/mariadb/datetime/)
## URL
An address of a specific Web site or file on the Internet.
```wp-block-preformatted
http://www.example.com/
http://www.example.com/reports/index.html
```
## UTC
**UTC** («Universal Time, Coordinated») is the basis of international time standards
from which time zones around the world are calculated. For most purposes it is the
same as the older [GMT](https://codex.wordpress.org/Glossary#GMT) standard.
* External link: [UTC](http://en.wikipedia.org/wiki/Coordinated_Universal_Time)(

## Servidor web
A **web server** is a computer containing software for, and connected to infrastructure
for, _hosting_, or serving, web sites written in [HTML](https://codex.wordpress.org/Glossary#HTML).
The most common web server software on the internet is [Apache](https://codex.wordpress.org/Glossary#Apache),
which is frequently used in conjunction with [PHP](https://codex.wordpress.org/Glossary#PHP),
[Perl](https://codex.wordpress.org/Glossary#Perl), and other scripting languages.
It is possible to create one’s own web server, hosted on any speed of internet connection,
but many people choose to purchase packages from [hosting providers](https://codex.wordpress.org/Glossary#Hosting_provider),
who have the capacity and facilities to provide adequate bandwidth, uptime, hardware,
and maintenance for frequently-visited web sites.
* Related articles: [Hosting WordPress](https://codex.wordpress.org/Hosting_WordPress)
## Widget
In WordPress a **widget** is a self-contained area of a web page that performs a
specific function, or the code that generates such a self-contained area. For example,
WordPress has a built-in widget that displays a list of pages in a weblog’s [sidebar](https://codex.wordpress.org/Glossary#Sidebar),
and it has another built-in widget that displays a list of recent comments in the
[Dashboard](https://codex.wordpress.org/Glossary#Dashboard). Plugins and themes
can provide additional widgets.
* Related articles: [WordPress Widgets](https://codex.wordpress.org/WordPress_Widgets),
[Widgets API](https://codex.wordpress.org/Widgets_API), [Dashboard Widgets API](https://codex.wordpress.org/Dashboard_Widgets_API)
### Widget Area
Furthermore, a «Widget Area» is a pre-defined location, in the code of your WordPress
Theme, that allows users to place Widgets into.
## XFN
[The XHTML Friends Network](http://gmpg.org/xfn). A decentralised project to have
inter-blog links that represent relationships between bloggers. XFN links resemble`
Photo Matt`.
## XHTML
**XHTML**, or **Extensible HyperText Markup Language**, is the successor to [HTML](https://codex.wordpress.org/Glossary#HTML)
as the [W3C](http://www.w3.org) standard language with which all web pages are created.
It is often used in conjunction with [CSS](https://codex.wordpress.org/Glossary#CSS)
and [JavaScript](https://codex.wordpress.org/Glossary#JavaScript).
WordPress strives to conform to the XHTML 1.0 Transitional standard.
* External links: [XHTML 1.0 Specification (Second Edition)](http://www.w3.org/TR/xhtml1/),
[XHTML 1.1 Specification](http://www.w3.org/TR/xhtml11/)
## XML
**XML**, or **Extensible Markup Language**, is written in Standard Generalized Markup
Language (SGML) and essentially allows you to define your own markup language. XML
is extremely useful in describing, sharing, and transmitting data across the Internet.
Typically used in conjunction with [HTML](https://codex.wordpress.org/Glossary#HTML),
XML defines data and [HTML](https://codex.wordpress.org/Glossary#HTML) displays
that data.
* External links: [Extensible Markup Language (XML) Resources at W3C org](http://www.w3.org/XML)
[XML 4.0 FAQ](http://www.ucc.ie/xml), [Overview of SGML Resources at W3C org](http://www.w3.org/MarkUp/SGML/)
## XML-RPC
**XML-RPC** is **Extensible Markup Language-Remote Procedure Call**. A Remote Procedure
Call (RPC) allows you to call (or request) another application and expect that application
to honor the request (answer the call). So, **XML-RPC** allows a user (or [developer](https://codex.wordpress.org/Glossary#Developer))
to send a request, formatted in [XML](https://codex.wordpress.org/Glossary#XML),
to an external application.
