6. Components A component is the largest and most complex of the extensions They are like mini applications that load in the main body of the page. There are two parts in a component - an administrator part and a frontend site part. Examples: com_content, My Blog, VirtueMart,

7. Modules Modules are more lightweight and flexible extensions Sometimes modules are linked to components such as the “latest news” module which links to the com_content and displays links to the newest content items. Modules are mostly found as the “boxes” that are arranged around a component, for example: the login module. Modules are assigned on a page based on menu items. They don't have to be related to anything and can be just static HTML or text. Examples: latest news, polls, weather, ads, banners
