It's actually GIDs and SUIDs. They stand for GroupID and SuperUserID, respectively. The latter is also reffered to as SwitchUserID (see what 'su' stands for). There's also UserID=UID as well. All of them are numbers that refer to a user or group. A regular user usually has an UID>=1000 and probably the same GID, root will have 0/0.
There is also the concept of suid,gid and sticky bits, which set the permissions on files/directories.

Thanks, I'll have a gander.

Probably take a while to sink in but eventually...
