Admin template The template used to specify the layout of the administrator back end of a Joomla site. The Back-end Template controls the way your website's administrative tasks are presented for controlling management functions by a Joomla! Administrator. These would include common tasks such as: user, menu, article, category, module, component, plugin and template management.
Template override Template overrides are a way of changing the way Joomla shows something without changing the basic or core Joomla system. A template override is a layout file that is placed in a special subfolder of the template. If found, it will replace the standard layout file for that template.This means that as Joomla is upgraded to new versions you will not have to repeat all the changes you made.
Search engine friendly (SEF) Search-engine friendly URLs. Refers to URLs that are descriptive in a way that search engines can understand. Normal Joomla! URLs look something like this: http://www.yoursite.org/index.php?option=com_content&view=section&id=3&Itemid=41 You can optionally have URLs display to look like static HTML pages like this: http://www.yoursite.org/faq.html Joomla! 1.5 has built-in optionos for SEF URLs. These are enabled by changing the ""SEO Settings"" in the Site tab in the Global Configuration screen in the Joomla! back-end. There are also third-party extensions that create SEF URLs for Joomla!.
