Consider five processes with given burst time: P1 (burst time: 24 units of time), P2 (burst time: 3 units of time), P3 (burst time: 10 units of time), P4 (burst time: 5 units of time), and P5 (burst time: 3 units of time). Here, Time Quantum is 4 units of time. Initially, processes are in the ready queue in this order: P1 (first process in the ready queue), P2, P3, P4, P5 (last process in the ready queue). The time for context switch is 1 unit of time. Answer the following questions based on Round-Robin scheduling algorithm: a. Draw a Gantt chart to demonstrate the order in which processes will be selected for scheduling. b. What will be the waiting time for each of five processes? c. What will be the turnaround time for each of five processes? d. What will be the average turnaround time, if we add the time for context switch to the turnaround time?
