CPU scheduling algorithms have some criterias and characteristics which are used to suit the best algorithms.These criterias
are :
⒈CPU Utilization:Keep the CPU as busy as possible.CPU Utilization should range from 40 percent to 90 percent.In this range,the
busier CPU is ,the better algorithms are.
⒉Throughput:It is a measure of work is the number of processes that are completed per time unit.For long processes and short transactions,throughput are different.
⒊Turnaround time:The inte
