OS Process Q & A #2

Question: What are the advantages of multiprogramming?

Answer: Advantages of multiprogramming are −

1. Increased CPU Utilization − Multiprogramming improves CPU utilization as it organizes a number of jobs where CPU always has one to execute.

2. Increased Throughput − Throughput means total number of programs executed over a fixed period of time. In multiprogramming, CPU does not wait for I/O for the program it is executing, thus resulting in an increased throughput.

3. Shorter Turn around Time − Turnaround time for short jobs is improved greatly in multiprogramming.

4. Improved Memory Utilization − In multiprogramming, more than one program resides in main memory. Thus memory is optimally utilized.

5. Increased Resources Utilization − In multiprogramming, multiple programs are actively competing for resources resulting in higher degree of resource utilization.

6. Multiple Users − Multiprogramming supports multiple users.
