In addition to the processes listed below, the system also has an idle task (which consumes no CPU resources and is identified as Pzale). This task has priority 0 and is scheduled when- ever 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. a. Show the scheduling order of the processes using a Gantt chart. b. What is the turnaround time for each process? c. What is the waiting time for each process? d. What is the CPU utilization rate?
