Consider multilevel queue scheduling where four queues are present. Queue 1 takes processes with priority values 1-5, Queue 2 takes processes with priority values 6-12, Queue 3 takes processes with priority values 13-20 and Queue 4 takes rest of the processes. Queue 1 uses round robin scheduling wit time quantum 4 and Queue 2 uses round robin scheduling wit time quantum 5. Queue 3 and 4 use FCFS. Draw the Gantt chart and calculate average waiting time for the processes shown in the following table. Process P1 X P2 X P3 XP4 * P5 XP6 X P7 XP8 X P9 Priority 25 6 Process P1 P2 P3 P4 P5 4 14 3 (17 (20 15 1. Burst time 7 4 12 Arrival Time 0 5 10 16 25 2 9 8 THIS SITE you..
