Q. When virtual memory is executed in a computing system there are convinced costs associated with the technique and certain benefits. List the costs as well as the benefits. Is it probable for the costs to surpass the benefits? If it is what measures can be taken to ensure that this doesn't happen?
Answer: The costs are additional hardware in addition to slower access time. The benefits are good use of memory and larger logical address space than physical address space.
Synchronization can be achieved by means other than locks and condition variables. One alternative is semaphores. A semaphore is used to regulate traf?c in a critical section. A se
