Modules are small blocks of content that can be displayed in positions on a web page. The menus on this site are displayed in modules. The core of Joomla! includes 24 separate modules ranging from login to search to random images. Each module has a name that starts mod_ but when it displays it has a title. In the descriptions in this section, the titles are the same as the names.
Content modules display article and other information from the content component.
User modules interact with the user system, allowing users to login, show who is logged-in, and showing the most recently registered users.
These modules display information from components other than content and user. These include weblinks, news feeds and the media manager.
Utility modules provide useful functionality such as search, syndication and statistics.
