Consider the following set of processes, with the length of the CPU burst time given in milliseconds. The processes are assumed to have arrived in the order P1, P2, P3, P4 and P5, all at time 0.

In order to analyze the scheduling of the given set of processes, we need to consider various scheduling algorithms such as FCFS (First Come First Serve), SJF (Shortest Job First), SRTF (Shortest Remaining Time First), and RR (Round Robin). Let us analyze the performance of each of these algorithms for the given set of processes.

FCFS (First Come First Serve): In this scheduling algorithm, the processes are executed in the order in which they arrive. The performance of FCFS depends on the order in which the processes arrive, and it may lead to a phenomenon known as convoy effect, where a long process arriving first may delay the execution of shorter processes that arrive later.

For the given set of processes, the execution sequence would be P1-P2-P3-P4-P5, and the average waiting time would be (0+5+8+12+19)/5 = 8.8 ms. The turnaround time for each process would be (5, 8, 12, 19, 25) ms respectively. Thus, the average turnaround time would be (5+8+12+19+25)/5 = 13.8 ms.
