Question

Difference between multiprogramming and multiprocessing operating system

Answer 1

Multiprocessing Multiprogramming

1) Multiprocessing refers to processing of multiple processes at same time by multiple CPUs.

1) Multiprogramming keeps several programs in main memory at the same time and execute them concurrently utilizing single CPU.

2 )It utilizes multiple CPUs.

2) It utilizes single CPU.

3)It permits parallel processing.

3)Context switching takes place.

4) Less time taken to process the jobs.

4More Time taken to process the jobs.

5) It facilitates much efficient utilization of devices of the computer system.

5)Less efficient than multiprocessing.
