== Extensions == <!--T:15-->

<!--T:16-->
Joomla! code consists of several different types of Extension:

<!--T:17-->
* '''Components''' control what appears in the main part of each page. Examples include the Content Component for articles and the Smart Search Component for search results.
* '''Modules''' contain code to manage the boxes that appear at the top, left, right or bottom of a page. Examples include a Login Module, a Menu Module and a Footer Module.
* '''Plugins''' add functionality to the site. Examples include Authentication options, Captcha options and Editor choices.
* '''Templates''' display page output to your specifications.
* '''Languages''' allow you to choose one or more languages in which to display and/or manage your content.
* '''Libraries''' are something for developers only.

<!--T:18-->
Joomla! has all the core Extensions you need for most types of personal and community websites. You only need to look for third party Extensions for more complex requirements such as sales and marketing.
