Joomla extentions extend the functionality of joomla websites.There are five types of extentions

1)Components are the largest and most complex extentions.Most  components have two parts: a site part and an administration part. Every time a Joomla page load one component is called to render the main page body. Component produces major portion of a page because a component is driven by a menu item.

2)Plugins are advanced extensions and  in essence they are also event handlers. In the execution of any part of Joomla, a module or  component, an event can be triggered. When an event is being triggered, plugin that are registered to handle that event executement. For example, a plugin can be used to block user-submitted articles and filter the text. The lines between plugin and component can sometimes be a little fuzzy. Sometimes larger or advanced plugin are called components even though they don't actually render large portion of a page. An SEF URL extensions might be created as  component, even though its functionality can be accomplish with just a plugin.

3)Templates describe the main design of a Joomla websites. While the CMS manage the website contents, templates determine the style and layout of a site.

4)Modules render pages in the Joomla. They are linked to Joomla component to display new content or image. Joomla modules look like box, such as search and login module. However, they do not require HTML in Joomla to work.

5)Languages are very simple extensions that can either be used as a core part or as an extension. Language and font information can also be used for PDFor PSD to Joomla conversions.
