WebNow at time=9, there are three processes which are P3, P4 and P5 (which arrived at time= 4, 6 and 8 respectively). Since the service time of P5 is 2 which is minimum as compared to that of P3 and P4, so P5 is now executed and it gets completed at time=9+2=11. At time=11, we have two processes which are P3 and P4 (which are arrived at time= 4 ... WebFeb 27, 2024 · SJF algorithm is helpful in batch operating where the waiting time for job completion is not critical. SJF improves the throughput of the process by ensuring that the shorter jobs are executed first, thus the possibility of less turnaround time. SJF enhances the output of the job by executing the process, which is having the shortest burst time.
