PreviousDescribe the differences among short-term, medium-term, and long-term scheduling.NextConsider a system running ten I/O-bound tasks and one CPU-bound task. Assume that the I/O-bound tasks issue an I/O operation once for every millisecond of CPU computing and that each I/O operation takes 10 milliseconds to complete. Also assume that the context-switching overhead is 0.1 millisecond and that all processes are long-running tasks. Describe the CPU utilization for round-robin scheduler when: (i) the time quantum is 1 millisecond; (ii) the time quantum is 10 milli-seconds.
