In our company we use the term admin and super admin.
Admin - refers to the person who will handle the users, this is preferably from the external (maybe a manager of our client)
Superadmin - refers to the person who will handle the admins, preferably this is internal (a personnel that should be working in our company)
But I am looking for the standard definition of those, I've tried searching it on google but all of the results correspond to specific system (like wordpress, google, etc) and they are the one who defines it.
Is there a standard definition of admin and superadmin?
