algorithm. each process is assigned a numerical priority, with a higher number indicating a higher

consumes no cpu resources and is identified as pidle ). this task has priority 0 and is scheduled

whenever the system has no other available processes to run. the length of a time quantum is 10

units. if a process is preempted by a higher-priority process, the preempted process is placed at

the end of the queue.
