Question
Let the processes P1, P2, P3, and P4 be given. They arrive in the
system at the same time in this order. The processes have the
following service times (in time units):
Process
Service time
(CPU burst)
P1
53
P2
17
P3
68
P4
24
2) For the scheduling method "Round Robin" (RR), specify the
average execution time (average turnaround time) and the number of
context switches. The time quantum q is set to 20 time units. You
must show your calculations. You will not have to draw Gantt charts.
Note: For RR, processes execute in order of their ID (i.e., P1-P2-P3-
P4).
