Part I Assume that the ready queue has just received for processes: P1, P2, P3, P4, in that order. All at time 0. The CPU execution times for these processes are as follows: Process Execution Time P1 P2 P3 P4 13 8 15 6 Draw the Gantt chart and calculate the metric listed in parentheses for each of the following scheduling algorithms: 1. First Come, First Served (Total Wait Time) 2. Shortest Job First (Total Wait Time) 3. Round Robin, with a time quantum of 5 ms (Total Wait and Response Times) Part II Now assume that P1 arrives in the ready queue at time 0, P2 arrives at time 4, P3 arrives at time 10, and P4 arrives at time 20. The CPU execution times for the processes are the same as in Part I: Process Execution Time P1 P2 P3 P4 P1 13 P2 8 P3 15 P4 6 Draw the Gantt chart and calculate the total wait time for each of the following scheduling algorithms: 1. Shortest Job First 2. Shortest Remaining Time Next (remember, this is a preemptive algorithm) 3. Preemptive priority with the…

Find our estimate for its next burst with a)4 ms b)4.5 ms c)3.5 ms d)5 ms
Shortest Process First (SPF) scheduling in a multiprocessing system is unrealistic because (select the correct choice): O Processes may stop execution before their allowed time expires. O Total process execution times are not known in advance. O Process /O requirements are not predictable. O Process execution burst durations are not known in advance. O Process time slices may end before execution times are completed.
