Language Pack An installable language extension that provides the option to view a Joomla site in a different language. Language packs can be for the front or back end of the site. With Joomla!, language-files are stored within the folder languages, and within that directory for each language a subdirectory is created.
Front-end The Joomla site that is accessed by visitors without user privileges. Front page refers to the public home page of your Joomla site.
Manager A user level on a Joomla site with access permissions to the back-end (via a separate log in) and some front-end privileges. Think of Manager users as Publishers, with Back-end access.
