We can view an operating system as a resource allocator. Explain.
We can outlook an operating system as a resource allocator. A computer system has Many resources (software and hardware) that may be necessary to solve a problem: memory space,I/O devices, CPU time, and so on. The operating system acts as the manager of these resources and allocates them to specific programs and users as necessary for tasks. Since there perhaps many-possibly conflicting-requests for resources, the operating system ought to decide which requests are allocated resources thus that it can operate the computer system efficiently and fairly.

A control program controls the carrying out of user programs to prevent improper use and errors of the computer. It is principally concerned with the operation and control of I/O devices.
