Site, also known as the Frontend.
Administrator, also known as the Backend. It is here that you can make major customisations for your site or Frontend. You can set up how your template looks or you can add new extensions such as components, languages, modules, plugins and templates from the Joomla! Extensions Directory (JED).
Installer is an application that helps you to install and configure Joomla on your website. Follow the next steps at Installer. This application should be deleted as soon as installation is completed.

-In Joomla! there are three possible applications: '''Administrator''', '''Site''', and '''Installation'''. Each application extends the abstract base class '''JApplication''' with objects '''JAdministrator''', '''JSite''', and '''JInstallation''' respectively.<br /><br />

-The Joomla! 1.5 framework uses the global variable '''$mainframe''' to reference the [[Application]] object. '''$mainframe''' is an object of type '''JAdministrator''', '''JSite''' or '''JInstallation''' depending on the application currently running.
-This provides an easy way for extensions to reference global application properties and methods without having to be concerned with which Application object is currently being referenced. When a component is operating in the backend, '''$mainframe''' will be pointing to the '''JAdministrator''' Application object. When a component is operating in the frontend, '''$mainframe''' will be pointing to the '''JSite''' Application object. During installation, '''$mainframe''' will be pointing to the '''JInstallation''' Application object.
-'''JAdministrator''', <strong>JSite</strong> and '''JInstallation''' are not documented or found on api.joomla.org because they are extended classes of '''JApplication''' and not the framework.  The '''JApplication''' class is documented on api.joomla.org since it is part of the core.  The '''JSite''' and '''JAdministrator''' classes extend '''JApplication''' with methods and properties specific to their frontend or backend requirements.

-'''NOTE:'''
-The use of the global variable '''$mainframe''' has been deprecated as of 1.5 and has been removed in 1.6.<br /><br />

-<source lang='php'>
-    global $mainframe;
-</source>
-<br />
-Instead, use:
-<br /><br />
-<source lang='php'>
-    $app = JFactory::getApplication();
-</source>
-<br />
-Please note that the variable '''''$app''''' is totally arbitrary. You could use '''''$mainframe''''' if it reduces the number of changes required throughout your code, for example:
-<br /><br />
-<source lang='php'>
-    $mainframe = JFactory::getApplication();
