Simulation of First Come First Served (FCFS) and Shortest Job First (SJF) Algorithms

Abstract

-Development of scheduling algorithms is directly related with the development of operating system which brings difficulties in implementation. Any modification on the scheduling algorithm will appear as modification on the operating system kernel code. Processor is an important source of cpu scheduling process, so it becomes very important on accomplishing of the operating system design goals. A delicate problem of the well-functioning of SO is the case when in CPU comes two or more processes which wants to be executed. Scheduling includes a range of mechanisms and policies that SO has to follows in order that all processes take the service. In this Paper we will discuss about two main batches algorithms, such as FCFS and SJF, and i will show a manner how to improve these algorithms in the future work.
