Q1.What are Optimization Criteria for CPU Scheduling ?

1.CPU utilization. We want to keep the CPU as busy as possible. Conceptually CPU utilization can range from 0 to 100 percent. In a real system it should range from 40 percent (for a lightly loaded system) to 90 percent (for a heavily used system).

2.Throughput. If the CPU is busy executing processes then work is being done. One measure of work is the number of processes that are completed per time unit called throughput. For long proce
