Multi programming

Question

Explain multi programming?

Answer 1

Multi programming: Multiprogramming is the technique of running many programs at a time by using timesharing. This allows a computer to do many things at the similar time. Multiprogramming develops logical parallelism. The concept of multiprogramming is that the operating system keeps many jobs in memory simultaneously. The operating system choose a job from the job pool and begin executing a job, while that job needs to wait for any i/o operations the CPU is switched to another job. Therefore the main idea here is that the CPU is never idle.
