You are required to analyze a set of processes using various CPU scheduling algorithms. For each algorithm, you will draw a Gantt chart, count the number of context switches, calculate the waiting times for each process, and determine the average waiting time for the set of processes. Follow the steps below for each scheduling algorithm provided. Process Arrival Time Burst Length P₁ 0 P2 1 P3 2 P4 3 8 + 166 5 You will use the following scheduling algorithms: A. First-Come, First-Served (FCFS) B. Shortest Job First (SJF) C. Round Robin (RR) with a time quantum of 3 D. Priority Scheduling (Assume the following priorities: P₁ = 2, P₂ = 1, P3= 4, P4 = 3, higher has precedence) For each scheduling algorithm listed above:| Draw a Gantt chart showing the schedule for the processes (when they are running) Count the number of context switches for each process. Calculate the waiting time for each process. Calculate the average waiting time for the set of processes. NOTE: Make sure that your Gantt charts clearly show the start and stop times for each process. Processes may stop and start multiple times before they finish. Show all calculations. Again note as priorities increase, processes gain precedence. They will preempt lower priority processes.
