Explanation:
Default permission levels
Permission levels are collections of permissions that allow users to perform a set of related tasks.
SharePoint Foundation 2010 includes five permission levels by default. You can customize the
permissions available in these permission levels (except for the Limited Access and Full Control
permission levels), or you can create customized permission levels that contain only the permissions
you need. The following table lists the default permission levels for team sites in SharePoint
Foundation 2010.
