WebMay 7, 2024 · Example of FCFS Disk Scheduling Algorithm. Suppose a disk contains 200 tracks (0-199) and the request queue contains track no: 93, 176, 42, 148, 27, 14,180. The current position of the read/write head is 55. Now we have to calculate the total number of track movements of read/write head using FCFS scheduling. WebFeb 27, 2024 · The advantages of Shortest Job First scheduling are: SJF is basically used for Long Term Scheduling. The average waiting time of Shortest Job First (SJF) is less than the FCFS (First-Come, First Serve) algorithm. For a particular set of processes, SJF provides the lowest average waiting. In terms of the average turnaround time, it is optimal.
