a) Draw four Gantt charts that illustrate the execution of these processes using the

following scheduling algorithms

  • First- Come, First-Served (FCFS) Scheduling
  • Shortest-Job-First (SJF) Scheduling
  • RR (quantum = 10)
  • Multiple level with 3 Queues:

    • Q1 : RR with quantum 10

    Q2: RR with quantum 20

    Q3: FCFS

    b) What is the turnaround time and response time of each process for each of the

    scheduling algorithms in part a?

    c) Calculate the average waiting time for the first three algorithms
