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

Consider the following set of processes (a smaller priority number implies a higher priority). The processes are assumed to have arrived in the order P1, P2, P3, P4, P5 all at time 0. Process Priority Burst Time P1 1 20 P2 3 25 P3 4 25 P4 2 15 P5 5 30   Draw four Gantt charts that illustrate the execution of these processes using the following scheduling algorithms: FCFS, SJF (if two jobs have the same burst time, schedule them following priority), and non-preemptive priority.

Part I Assume that the ready queue has just received for processes: P1, P2, P3, P4, in that order. All at time 0. The CPU execution times for these processes are as follows: Process Execution Time P1 P2 P3 P4 13 8 15 6 Draw the Gantt chart and calculate the metric listed in parentheses for each of the following scheduling algorithms: 1. First Come, First Served (Total Wait Time) 2. Shortest Job First (Total Wait Time) 3. Round Robin, with a time quantum of 5 ms (Total Wait and Response Times) Part II Now assume that P1 arrives in the ready queue at time 0, P2 arrives at time 4, P3 arrives at time 10, and P4 arrives at time 20. The CPU execution times for the processes are the same as in Part I: Process Execution Time P1 P2 P3 P4 P1 13 P2 8 P3 15 P4 6 Draw the Gantt chart and calculate the total wait time for each of the following scheduling algorithms: 1. Shortest Job First 2. Shortest Remaining Time Next (remember, this is a preemptive algorithm) 3. Preemptive priority with the…
