2 Consider the following set of processes, with the length of the CPU burst given in milliseconds The processes are assumed to have arrived in the order $$A,B,C$$, and $$D$$ all at time 0 . (i) Draw four Gantt charts that illustrate the execution of these processes using the following scheduling algorithms: Shortest Job First (SJF), First Come First Served (FCFS), Round Robin (RR), Modified Round Robin (MRR) which gives priority 1 processes a double quantum and priority 2 processes a single quantum whenever they are scheduled. [5] (ii) Calculate the average turnaround time for each of these scheduling algorithms. [5] (iii) Calculate the average waiting time for each of these scheduling algorithms. [5]
