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. WebFirst Come First Served (FCFS) is a Non-Preemptive scheduling algorithm. FIFO (First In First Out) strategy assigns priority to process in the order in which they request the processor. The process that requests the CPU … WebJan 24, 2024 · CPU Scheduling involves many different scheduling algorithms which have their Advantages and Disadvantages. 1. First Come First Serve (FCFS): Advantages: It is simple and easy to understand. Disadvantages: The process with less execution time suffers i.e. waiting time is often quite long. Favors CPU Bound process then I/O bound process. camberley eye facebook
