If you have replete primary memory(RAM) e.g greater than 2GB then you may need not any swapping memory space for desktop users(I am victimisation Ubuntu 10.04 LTS and total RAM is 4GB so I am not feeling any trouble without swap memory space) and some times using swap memory may torpid down your computer performance. 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 stir up to swap out the process that just completed oand to swap other(prenominal) process into the memo ry space that has been freed. oIn the mean! time, the CPU scheduler will apportion 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 photosensitive amounts of computing to be done between swaps. A fragmented of this swapping policy is used for priority-based scheduling algorithms. This variant of swapping is sometimes called wee out, roll in. Normally, a process that is...If you want to get a full essay, order it on our website: BestEssayCheap.com
