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):
P2
17
Process
Service time
(CPU burst)
P1
53
P3
68
P4
24
For the scheduling method "Shortest Job First" (SJF), specify the
execution order of the processes, the average execution time
(average turnaround time) and the average waiting time over all
processes. You must show your calculations. You will not have to
draw Gantt charts.
