CPU Scheduling is an area of research where computer scientists used to design efficient algorithms for scheduling the processes in order to get output in the form of optimum turn around time and average waiting time. There are many CPU scheduling schemes available like FCFS, SJF, RRS, PBS, Multilevel queue scheduling and so on. This paper analysis the four scheduling policies FCFS, SJF, RRS, PBS and gives the result which policy is the best among them. A comparative analysis is made on the basis of data generated through the simulation using exponentially generated random numbers.
