The operating systems avoid migrating it keeps users may be moved across processors are assigned to face and short programs are allocated to. Various operating systems follow various scheduling algorithms12The classic scheduling algorithms include First Come First ServeFCFSShortest Job First. The benefit of the algorithm is that each process is given a proportional share of the CPU. Which depends on the scheduling algorithm used When time. This avoids the time delay of going out to the external memory bus to access memory and provides a huge boost to performance. What is the best scheduling algorithm? In UNIX, Which system call creates the new process? Algorithms to used are Multi level Queue scheduling. The queue of jobs is sorted by estimated job length so that short programs get to run first and not be held up by long ones.
