Comparison Analysis of CPU Scheduling : FCFS, SJF and Round Robin Task scheduling is needed to maintain every process that comes with a processor in parallel processing. In several conditions, not every algorithm works better on the significant problem. Sometimes FCFS algorithm is better than the ...
It termed as First Come First Serve (FCFS) Scheduling. As its name implies, the process which arrives first in front of CPU for processing, then that process executed first. It is a non-preemptive scheduling algorithm which means in this priority of processing does not matter, i.e., whate...
In this tutorial, we will learn about the FCFS, i.e. First Come First Serve Scheduling Algorithm with the help of example.

How to Avoid Convoy Effect in FCFS Scheduling?Preemptive scheduling like round-robin scheduling can be used to avoid Convoy Effect as in these algorithms every process will be given an equal chance to access the CPU. By using these smaller processes don’t have to wait much for CPU time –...

When P1 is first put in the queue, the wait time is zero and the CPU starts the processing immediately. P2, on the other hand, would have a wait time of 25 seconds. And P3, having arrived last, would have to wait 35 seconds. As a total, an FCFS scheduling algorithm would need 50...
