5. CONCLUSION
In terms of computing power, the CPU is the most important element of a computer system. CPU scheduling involves a careful examination of pending processes to determine an improved way to service the requests. Many CPU scheduling algorithms have been presented having some advantages and disadvantages. In this paper An Augmented Dynamic round robin CPU scheduling algorithm is proposed. ADRR with varying time quantum proposed in this paper giving better performance than conventional RR algorithm. Simulation results shows that the proposed ADRR CPU scheduling algorithm is more efficient than conventional RR algorithm also prove the correctness of the theoretical results. After improvement in RR it has been found that the waiting time and turnaround time have been reduced drastically. This algorithm can be implemented to improve the performance in the systems in which RR is a preferable choice.
