Problem $4$

Consider $5$ processes, A$,$ B$,$ C$,$ D and E$,$ arriving to a system with a single CPU according to the table below.

Each process has an arrival time and service time $($time needed on the CPU$).$ Assume the CPU services these

processes in a First$-$in$-$First$-$Out $($FIFO$)$ fashion. Also assume that the CPU is used $100\%$ of the time during

the service time of any process.

Answer the following questions $[2$ pts each$]$:

$($a$)$ How long would it take until all the processes are done?

$($b$)$ Draw the utilization of the CPU over time?

$($c$)$ What is the average utilization of the CPU?

$($d$)$ What is the overall system throughput in processes done per second?

$($e$)$ What is the average turnaround time for all processes?
