Consider the following set of processes, with the length of the CPU burst given in milliseconds: Process P₁ P₂ P3 PA Ps Burst Time Priority C. 2 1 8 4 5 21423 2 4 2 3 The processes are assumed to have arrived in the order P₁, P2, P3, P4, P5, all at time 0. a. Draw four Gantt charts that illustrate the execution of these processes using the following scheduling algorithms: FCFS, SJF, nonpreemptive priority (a larger priority number implies a higher priority), and RR (quantum = 2). b. What is the turnaround time of each process for each of the scheduling algorithms in part a? What is the waiting time of each process for each of these schedul- ing algorithms? d. Which of the algorithms results in the minimum average waiting time (over all processes)?
