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 22, 2024 · SJF stands for Shortest Job First scheduling, which is a scheduling algorithm used in operating systems for scheduling tasks or processes. In this algorithm, the process with the shortest burst time or execution time is executed first. The idea behind this algorithm is to minimize the average waiting time for all processes. WebNov 11, 2005 · The Shortest Job First (SJF) algorithm reduces the average waiting time of processes in a CPU environment; however, it may lead to the starvation of long processes.

WebDec 29, 2024 · The shortest job first (SJF) is also known as the shortest job next (SJN). For example, we have 4 processes P1, P2, P3, and P4 with burst times of 5, 7, 6, and 2. Now, first, process P4 will be executed as it has less burst time. After that, processes P1, P3, and P2 will be executed respectively. Shortest job first scheduling Algorithm : WebThe Preemptive version of Shortest Job First (SJF) scheduling is known as Shortest Remaining Time First (SRTF). With the help of the SRTF algorithm, the process having the smallest amount of time remaining until completion is selected first to execute. So basically in SRTF, the processes are scheduled according to the shortest remaining time.

WebIn the Shortest Job First (SJF) algorithm, the scheduler selects the process with the minimum burst time for its execution. This algorithm has two versions: preemptive and non-preemptive. Advantages of SJF algorithm The algorithm helps reduce the average waiting time of processes that are in line for execution.
