Draw timeline, and calculate the average waiting time for all of the scheduling algorithms. Determine preemptive, fairness, starvation as well.

Eight batch jobs arrive almost at the same time in the following order: I₁, 2, ..., II8. The table below contains their running times and priorities: Job П1 П2 П3 П4 П П П П Running time (in min) 4 5 5 10 8 10 7 Priority 1 7 5 2 8 6 4 3 The highest priority is 1. For each of the following scheduling algorithms, determine the order of execution of processes and the mean process turnaround time: (a) priority scheduling; (b) first-come, first-served; (c) shortest job first. Scheduling is non-preemptive.

Consider the following processes schedule using RR Scheduling algorithm If the CPU scheduling policy is Round Robin with time quantum = 3 unit: Process Arrival time Burst Time P1 P2 P3 P4 P5 5 P6 4 3 1 2 5 6 6 7 9 2 Turn around time 3 Draw the ready queue, Gantt Chart for the schedule and find the TAT, WT, RT for each process then, find the Average waiting time, Response Time and the average turnaround time. Waiting Time Response Time

The Gantt chart method permits the development of scheduling algorithms that account for all precedence relations when the schedule is developed. True/False
