Philp said, nor could they reschedule: The scheduling system was down. CPU utilization:CPU utilization is the main task in which the operating system needs to make sure that CPU remains as busy as possible. CPU scheduling is the task performed by the CPU that decides the way and order in which processes should be executed.In CPU Scheduling there are various types of processes used to perform various tasks.In a preemptive scheduling system we use the notion of the time slice; a process is only active on a CPU while it is not blocked and it has not exhausted its time slice.
