Components are core elements of Joomla!'s functionality and are displayed in the main body of the Web site's template, i.e. mainbody.php. Depending on the design of the template in use, this is often in the center of the web page.

A typical Joomla! installation comes with Banners, Contacts, News Feeds, Polls and Web Links components.

Members of the Joomla! community produce third party Joomla! components on a continuous basis. Take a look at http://extensions.joomla.org/ or http://developer.joomla.org for a listing of available components downloads.
