The following processes are being scheduled using a preemptive, roundrobin scheduling algorithm. Each process is assigned a numerical priority, with a higher number indicating a higher relative priority, In addition to the processes listed below, the system also has an idle task (which consumes no CPU resources and is identified as I). 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 5 units If a process is preempted by a higher priority process, the preempted process is placed at the end of the queue. a.
