Suppose we have 8 processes (P1, P2, P3, P4, P5, P6, P7, P8) all arriving at the same time: Produce the Gantt chart for each type of scheduler and calculate the average waiting time for each schedule type. From there, state your reasons and indicate which scheduling type is the best, and why. (i) First Come First Serve (FCFS) Scheduling (ii) Shortest Job First (SJF) Scheduling (iii) Priority Scheduling (iv) Round Robin (RR) Scheduling (Quantum = 3)
