The processes have the following service times (in time units): Process P1 P2 P3 P4 Service time (CPU burst) 53 17 68 24 For the scheduling method "Round Robin" (RR), specify the average execution time (average turnaround time) and the number of context switches. The time quantum q is set to 20 time units. You must show your calculations. You will not have to draw Gantt charts. Note: For RR, processes execute in order of their ID (i.e., P1-P2-P3-P4).

By issuing an I/O, use the disk for 14 milliseconds. Use the CPU for 10 milliseconds. By issuing an I/O, use network for 18 milliseconds. Assume that each step depends on data obtained from the previous step (e.g., step 3 cannot start before step 2 is completed. Also assume that each resource (CPU or disk or network) can be used by one process at a time. Answer the following questions: (a) Draw 3 time-line diagrams (horizontal axis is the time line; one line for each resource. That is, 3 parallel rows in the resulted figure.) that illustrate the utilizations of the CPU, disk, and network over the execution of two iterations of the program above by a single process. (b) What are the average utilizations of the CPU, disk and network over these two iterations? (Please note that the “total time” should be the same across all resources, from the entire system starts until all work on any…
