(6+2+2 points) The following processes are being scheduled using a preemptive, priority-based, round- robin scheduling algorithm. Processes Arrival time Service time Priority P₁ 0 3 8 P2 0 4 3 P3 4 4 4 P4 8 4 4 P5 P6 5 5 5 5 15 18 Each process is assigned a numerical priority, with a higher number indicating a higher relative priority. The scheduler will execute the highest priority process. For processes with the same priority, a round- robin scheduler will be used with a time quantum of 3 time 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?
