List three main advantages of Virtual Memory.

Question:

List the main advantages of Virtual Memory.

Answer:

• A program need not be constrained by the amount of physical memory that is available. So, programmers would be able to write programs for an extremely large virtual address space, simplifying the programming task.

• Because each user program could take less physical memory, more programs could be run at the same time, with a corresponding increase in CPU utilization and throughput but with no increase in response time or turnaround time.

• Less I/O would be needed to load or swap user programs into memory, so each user program would run faster.
