2. [2 pts] Consider a system running ten I/O-bound tasks and one CPU-bound task (which never requires I/O operations). 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 milliseconds and that all processes are long- running tasks. What is the CPU utilization for a round-robin scheduler when: (1) The time quantum is 1 millisecond (2) The time quantum is 10 milliseconds
