Components are larger extensions that produce the major content for your site. Each component has one or more "views" that control how content is displayed. In the Joomla administrator there are additional extensions such as Menus, Redirection, and the extension managers.

The content component (com_content) is what you use to write articles. It is extremely flexible and has the largest number of built in views. Articles can be created and edited from the front end, making content the easiest component to use to create your site content. Help

The contact component provides a way to provide contact forms and information for your site or to create a complex directory that can be used for many different purposes. Help

News Feeds (com_newsfeeds) provides a way to organize and present news feeds. News feeds are a way that you present information from another site on your site. For example, the joomla.org website has numerous feeds that you can incorporate on your site. You can use menus to present a single feed, a list of feeds in a category, or a list of all feed categories. Help
