Part one: CPU Scheduling (30 Points) Consider the set of 5 processes whose burst time are given below. Process Arrival time CPU Burst Priority 10 5 P1 0 P2 7 3 P3 No 3 1 P4 4 2 P5 00 1 1 Draw the Gantt chart showing the Round Robin scheduling for these processes with time quantum = 3 unit. Calculate the average waiting time using Round Robin. Draw the Gantt chart showing the FCFS scheduling for these processes. . Calculate the average turnaround time using FCFS. Draw the Gantt chart showing the SJF scheduling for these processes. Calculate the average waiting time for these processes using SJF. Draw the Gantt chart showing the SRTF scheduling for these processes. . Find the response time for (P4) using SRTF scheduling. Draw the Gantt chart showing the Non Preemptive Priority scheduling for these processes. . Draw the Gantt chart showing the Preemptive Priority scheduling for these processes
