) Consider two CPU scheduling algorithms for a single CPU: Preemptive Shortest-JobFirst (also known as Shortest Remaining Time First) and Round-Robin. Assume that no time is lost during context switching. Given five processes with arrival times and expected CPU time as listed below, draw a Gantt chart to show when each process executes using a) Preemptive Shortest-Job-First (Shortest Remaining Time First). b) Round-Robin with a time quantum of 5. Of course, assume that the expected time turns out to be the actual time. Process Arrival Time Expected CPU Time P1 0 14 P2 2 9 P3 4 10 P4 8 4 P5 17 7
