  Abstract

One of the primary roles of the operating system is job scheduling. Oftentimes, what makes the difference between the performance of one operating system over the other could be the underlying implementation of its job scheduling algorithm. This paper therefore examines, under identical conditions and parameters, the comparative performances of First Come First Serve (FCFS), Shortest Job Next (SJN) and Round Robin (RR) scheduling algorithms. Simulation results presented in this paper serve to stimulate further research into the subject area.
