Consider a system running ten I/O-bound tasks and one CPU-bound task. Assume that the I/Obound tasks issue an I/O operation once for every millisecond of CPU computing and that each 1/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 is the CPU utilization for a round-robin scheduler when: 1. The time quantum is 1 millisecond 2. The time quantum is 10 milliseconds
