For First-Come-First-Served (FCFS) scheduling, analytic results for the mean waiting time are also given (in a closed form). If the objective of a schedule is to minimize the mean waiting time (or queue size) and its variance, the results seem to confirm the overall superiority of ...

3.FCFS doesn’t cause starvation to any request, but request can experience Convoy effect.In C-LOOK algorithm neither the requests suffers starvation nor Convoy effect. 4.FCFS is inefficient in seek movements.But it is very efficient in terms of seek movement in all the disk scheduling algorith...
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 FCFS scheduling the burst time of the first job is the highest among all the other jobs so this situation is referred to as a convoy effect.For example, there is one CPU intensive process (which has large burst time) in the ready queue, and many more other processes comparatively ...
