Joomla! 1.5.x Help Screens: Extensions Menu

How to Access


Select Extensions -> Install/Uninstall from the drop-down menu in the Back-end of your Joomla! installation.


Description


Extensions are add-ons that expand the functionality of Joomla!.
Extensions are used to add capabilities to Joomla! that do not exist in
the standard package. Hundreds of Extensions are available for Joomla!,
with more being developed all of the time.
Extensions are categorized into five types, as follows:

• A Component is a mini-application that renders the
  main body of the page. Examples of Components are Contacts, the Front
  Page, and News Feeds.
  
• A Module is a smaller Extension typically used
  for rendering a small element that displays across multiple pages.
  Examples of Modules include Menus and Related Items.
  
• A Plugin is a section of code that runs when a
  pre-defined event happens within Joomla!. For example, editors are
  Plugins that run when an edit session is opened.
  
• The Language Extension allows for the Front-end
  and Back-end of Joomla! to be presented in any language for which a
  language Extension exists. This way, Joomla! can be released in a new
  language with no changes to the core program.
  
• A Template controls the way the content of a web
  site is displayed, including the location and layout of elements,
  colors, fonts, and so on. Templates allow the appearance of the web
  site to be separated from it's content.
  

This screen is organized into six sections as follows:

• Install: Allows you to install all types of Extensions.
  
• Components, Modules, Plugins, Languages, Templates: Allow you to enable, disable, and uninstall Extensions of each type.
