You can create settings for four different types of accounts:
• User—Usually relates to a specific person. This is the account that the person identifies himself or herself with when logging in to the machine. A user’s short name or UID number uniquely identifies the user on a system.
• Group—Represents a group of users, a group of groups, or a mixture of both.
• Device—Similar to a user account, it’s the singular entity that represents a given piece of hardware. Device accounts are uniquely identified by their Ethernet ID, serial number, IMEI, or MEID.
• Device Group—Represents a group of computers or iOS devices, a group of device groups, or a mixture of both.
