Question

Three process p1, P2 and P3 arrive at time zero. Their total execution time is 10ms, 15ms, and 20ms respectively. They spent first 20% of their execution time in doing I/O, next 60% in CPU processing and the last 20% again doing I/O. For what percentage of time was the CPU free? Use Round robin algorithm with time quantum 5ms.

Step 1

To determine the percentage of time the CPU was free while executing the processes p1, p2, and p3 using the Round Robin scheduling algorithm with a time quantum of 5ms, we will follow these steps: Show more…
