An administrator in Joomla site context is a person with permissions of the Joomla backend "Administrator" user group.
As the Content Management System, Joomla has a permission level hierarchy. It determines what user is permitted to do what actions on the site.
The top level of this permission level structure are users of the "Super Administrator" group. They are allowed to perform anything on the site.
The "Administrator" user group is the second after the "Super Administrator". An Administrator is allowed everything allowed to a Super Administrator, except:
- Creating a user with the Super User group permissions
- Installing extensions on the site.
