WebJun 9, 2024 · 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. The burst time of only those processes is compared that are present or have arrived until that time. WebSJF Scheduling can be used in both preemptive and non-preemptive mode. Preemptive mode of Shortest Job First is called as Shortest Remaining Time First (SRTF). Advantages- SRTF is optimal and guarantees the minimum average waiting time. It provides a standard for other algorithms since no other algorithm performs better than it.
