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

WebQueue 1 has a higher priority than queue 2. Round Robin is used in queue 1 (Time Quantum = 2), while FCFS is used in queue 2.. Working: Both queues have been processed at the start. Therefore, queue 1 (P1, P2) runs first (due to greater priority) in a round-robin way and finishes after 7 units. The process in queue 2 (Process P3) starts running (since … WebThe FCFS scheduling technique is the simplest scheduling algorithm. In this scheduling, CPU schedules the processes on the basis of their arrival time. The processes are stored in a queue that follows a First In First Out (FIFO) structure. When a process arrives, it takes the CPU time and runs till it completes.

WebApr 5, 2024 · Disadvantages Of FCFS Scheduling FCFS results in convoy effect which means if a process with higher burst time comes first in the ready queue then the processes with lower burst time may get blocked and that processes with lower burst time may not be able to get the CPU if the higher burst time task takes time forever.
