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 algorithmic rule; when a quantum expires (see Fig. 8.5), oThe memory manager leave behind derail to swap out the process that just completed oand to swap some other(prenominal) process into the memory space that has been freed. oIn the meantime, the CPU scheduler will ! allot 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 huffy amounts of computing to be done between swaps. A preoccupied of this swapping policy is used for priority-based scheduling algorithms. This variant of swapping is sometimes called break out, roll in. Normally, a process that is...If you want to get a full essay, order it on our website: BestEssayCheap.com
