Consider a system running 10 I/O-bound processes and 2 CPU-bound process. Assume that the I/O-bound processes issue an I/O operation once for every millisecond of CPU computing and that each I/O operation takes 10 milliseconds to complete (we assume that there is no competition among I/O operations). Assume that the CPU-bound processes do not issue any I/O operations. A round-robin scheduler with quantum size 1 milliseconds is used to schedule all these 12 processes together. We assume that the context-switching overhead is 0.1 millisecond and that all processes are long-running tasks. Calculate the CPU utilization.
