Difference between component, module & plugin in joomla

A Plugin will manipulate output already generated by the system. It typically does not run as a stand-alone piece but takes data from other sources (i.e. the content) and manipulates it before outputting to the user window. A plugin typically does not display directly to a user but does it's work behind the scenes.

A module is typically considered to be an add-on to the site that extends the functionality of another part of the system. It usually has fewer options that are configurable by the end user and most of the time does not handle any storing of information into the database. A module usually occupies a secondary portion of the web page and is not considered the primary focus of a page.
