Problem 3 A system is running five I/O-bound tasks and one CPU-bound task. The I/O-bound tasks issue an I/O operation once for every millisecond of CPU computing and that each I/O operation takes 5 milliseconds to complete. Also assume that the context switching overhead is 0.1 millisecond (which does not count as the CPU being utilized) and that all processes are long-running tasks. Assume that each task uses a different IO device. What is the CPU utilization for a round-robin scheduler when: 1 I. The time quantum is 1 millisecond 2. The time quantum is 10 milliseconds Answer: The time quantum is 1 millisecond: The time quantum is 10 milliseconds
