WebFirst Come First Serve (FCFS) Jobs are executed on first come, first serve basis. It is a non-preemptive, pre-emptive scheduling algorithm. Easy to understand and implement. Its implementation is based on FIFO queue. Poor in performance as average wait time is high. Wait time of each process is as follows − Average Wait Time: (0+4+6+13) / 4 = 5.75 WebFCFS scheduling may cause the problem of starvation if the burst time of the first process is the longest among all the jobs. Advantages of FCFS Simple Easy First come, First served Disadvantages of FCFS 1. The scheduling method is non preemptive, the process will run to the completion. 2.
