Suppose that we have a multiprogrammed computer in which each job has identical characteristics. In one computation period, T$,$ for a job, half the time is spent in $1/0$ and the other half in processor activity. Each job runs for a total of a periods. Assume that a simple round$-$robin scheduling is used, and that I$/0)$ operations can overlap with processor operation. Define the following quantities: Turnaround time $=$ actual time to complete a job$*$ Throughput $=$ average number of jobs completed per time period $7\text{'}$ Processor utilization $=$ percentage of time that the processor is active $($not waiting$)$Compute these quantities for one, two, and four simultaneous jobs, assuming that the period T is distributed in cach of the following ways:$1/0$ first halt, processor second halfb. $1/0$ first and fourth quarters, processor second and third quarter
