A Survey on Research Trends for Modeling CPU Scheduling Algorithm

An operating system is the brain of a computer of computer system who constantly and continuously manages the resources available around the system in optimum way. One of the basic and most important tasks, an OS needs to perform, is job scheduling where many processing requests arrive from multiple channels to a ready queue and system manages all in a way to achieve high efficiency level. CPU scheduling is a fundamental operating system function that determines which of the process have to be executed next when multiple run able process are waiting in the ready queue. The aim of CPU scheduling is to execute by the processor or processors over time, in a way that meets system objectives such as response time, throughput, and processor's efficiency; In the proposed paper I have discussed the various approaches that can be used for this purpose & elaborate the research trends in this field. A Markov chain analysis is done in order to determine the performance of this suggested algorithm. These efforts have found very efficient and useful.
