Consider the following set of processes, with the length of the CPU burst time given
in milliseconds:
Process
Burst Time
Priority
P1

The processes are assumed to have arrived in the order P1 , P2 , P3 , P4 , P5 , all at
time o.
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 = 3).
b) What is the turnaround time of each process for each of the scheduling
algorithms in part a?
c) What is the waiting time of each process for each of these scheduling algorithms
im part a?
