Administrators and Users

There are 4 types of administrators for the machine: user administrator, machine administrator, network administrator, and file administrator.

Their main role is to specify the settings for operating the machine. Their access privileges depend on the administrator type. Administrators cannot perform normal operations, such as printing documents.

There is only one supervisor. The supervisor can specify each administrator's password. For normal operations, a supervisor is not required as administrators specify their own passwords.

Users are people who use the machine for normal operations, such as printing documents.
