Splet15. jun. 2024 · Shortest Job First (SJF): Shortest Job First (SJF) Scheduling Algorithm is based upon the burst time of the process. The processes are put into the ready queue based on their burst times. In this algorithm, the process with the least burst time is processed first. Splet16. 22. Initially only process P0 is present and it is allowed to run. But, when P0 completes, all other processes are present. So, process with shortest CPU burst P2 is selected and allowed to run till it completes. Whenever more than one process is available, such type of decision is taken. This procedure us repeated till all process complete ... Splet20. nov. 2024 · Criteria of shortest job first are burst time.
