Virtual memory is an illusion of extremely large memory.
When virtual memory is implemented in a computing system, there are
certain costs associated with the technique and certain benefits. List the
costs and the benefits. Is it possible for the costs to exceed the benefits?
If it is, what measures can be taken to ensure that this does not happen?
Answer: The costs are additional hardware and slower access time. The
benefits are good utilization ofmemory and larger logical address space
than physical address space.
