The following processes are being scheduled using a preemptive,

round robin schedulingalgorithm. Each process is assigned a numerical priority, with a

higher number indicating a higherrelative priority. In addition to the processes listed below,

the system also has an idle task $($whichconsumes no CPU resources and is identified as Pidle $).$

This task has priority $0$ and is scheduledwhenever 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 atthe end of the queue.

The following processes are being sche

duled using a preemptive priority, round robin scheduling algorithm.

Each process is assigned a numerical priority, with a lower number indicating a higher relative priority. The scheduler always selects the highest$-$priority process in the ready queue to be dispatched to run on the CPU. For processes with the same priority, a round$-$robin scheduler will be used with a time quantum of $4$ units. If a process is preempted, this process is placed back in the ready queue after other processes with the same priority values.

Draw the Gantt chart to show the scheduling order of the processes.

What is the turnaround time for each process? What is the average turnaround time of these processes?

What is the waiting time for each process? What is the average waiting time of these processes?
