A process essential be in memory to be executed. A process, however, can be swapped temporarily out of memory to a substitute store (disk) and then brought back into memory for continued execution.

A round-robin CPU-scheduling algorithm; when a quantum expires (see Fig. 8.5), oThe memory manager leave behind dispirit to swap out the process that just completed oand to swap another(prenomina l)(prenominal) process into the memory space! that has been freed. oIn the meantime, the CPU scheduler will share a time slice to some other process in memory. oWhen each process finishes its quantum, it will be swapped with another process. The quantum must be large enough to allow susceptible amounts of computing to be done between swaps. A disjointed of this swapping policy is used for priority-based scheduling algorithms. This variant of swapping is sometimes called expire out, roll in. Normally, a process that is...If you want to get a full essay, order it on our website: BestEssayCheap.com
