Question

State the term multi programming.

Answer 1

Multi programming:
It is the technique of running various programs at a time by using timesharing.
It permits a computer to do various things at same instant. It creates logical parallelism.
The notion of multiprogramming is that the operating system keeps various jobs in memory concurrently. The operating system chooses a job from the job pool and begins executing a job, when such job requires waiting for any I/O operations the CPU is switched to other job. Therefore the main idea is that the central processing unit is never idle.
