Consider the following set of processes, with the length of the CPU burst given in milliseconds: Process Burst time P1 10 P2 1 P3 2 P4 1 P5 5 The processes are assumed to have arrived in the order P1, P2, P3, P4, Ps, all at time 0. Context switching time is negligible. (1) Use a Gantt chart(excel spreadsheet) to illustrate the execution of these processes using FCFS and compute the average waiting time. (2) Use a Gantt chart(excel spreadsheet) to illustrate the execution of these processes using SJF and compute the average waiting time. (3) Use a Gantt chart(excel spreadsheet) to illustrate the execution of these processes using RR (quantum = 1 millisecond) and compute the average waiting time. a a -
