Development and Evaluation of Adobe Flash Based CPU Scheduling Simulator Executable on Major Multiple Web Browsers

Abstract

Currently, e-Learning system is one of the most popular and influential education tools and therefore not only designers but also their users must be requested to evaluate and improve such system very repeatedly and in a steady cyclic manner.We introduce an Adobe-Flash-based simulator for CPU scheduling algorithm in the lecture of Operating System. Our simulator supports three major CPU scheduling algorithms such as FirstCome-FirstServed, Shortest Processing Time First, and Round Robin. It can provide its services in the environments of stand alone utilization with Flash Player, of course, as well as major Web browsers such as Microsoft Internet Explorer, Mozilla FireFox and Google Chrome. As evaluation of our system, we have performed comparison of execution times for the above environment and quantitative/qualitative evaluation through information gleaned from users' questionnaire. It is confirmed that our system have obtained good and significant level performance through comparison and questionnaire.This paper reports our system configuration and its application to real lecture of Operating System. It also illustrates quantitative/qualitative evaluation through its practical utilization. With our system, we can provide fruitful lecture about CPU scheduling algorithm and some kinds of fruitful results.
