Consider a system running ten I$/$O$-$bound tasks and one CPU$-$bound task. Assumethat the I$/$O$-$bound tasks issue an I$/$O operation once for every $2$milliseconds of CPUcomputing and that each I$/$O operation takes $23$ milliseconds to complete. Also as$-$sume that the context switching overhead is $0\mathrm{.}2$milliseconds and that all processesare long$-$running tasks $($i$.$e$.,$ they run forever$).$ What is the CPU utilization for around$-$robin scheduler when:

$($i$)$ The time quantum is $2$milliseconds.

$($ii$)$ The time quantum is $10$ milliseconds
