What are the four types of separation supported by an OS?
What will be an ideal response?
Multiprogramming in the OS introduces the sharing of resources among users. This sharing involves data, memory, Input / Output devices such as disks, tape drives, processes, and hardware such as bus control, interrupt control, and status registers. The ability to share these resources prompts the need for protection, and the basis of OS protection is separation. There are four types of separation:
* Logical-Separate resources into domains. Each user works in the assigned domain. Access control is controlled at the domain level.
* Physical-Separate physical objects such as the CPU, hard disk, printer, and so on. These physical objects are assigned to a user for access control.
* Temporal-Separate each process for execution at different times.
* Cryptographic-Separate data from unconcerned users by encrypting them.
