Comparative Analysis of Various Scheduling Algorithms
Journal Title: International Journal of Advanced Research in Computer Engineering & Technology(IJARCET) - Year 2013, Vol 2, Issue 4
Abstract
Scheduling is the technique used for controlling the order of the job which is to be performed by a CPU of a computer. The motive of scheduling is to engage the CPU at its maximum capacity and no process shall wait for longer time and to finish the entire task in minimum possible time. In this paper, we discuss various types of Scheduling algorithms and Compare their performance on terms of throughput and waiting time. First of them is First Come First Served (FCFS) which is a non-preemptive and the simplest scheduling. FCFS is good for long job. Second is Shortest Job First (SJF) scheduling which selects that job first which has least processing time i.e. the processing demanding the less CPU time is executed first. Next is Round Robin (RR) scheduling, it removes the drawbacks of FCFS by preempting running jobs periodically. But if the length of time quantum is too short then more time will waste in context switching. Last one is Priority Based scheduling where each process is assigned a priority (preference) to create the order of execution.
