QUESTION 3: You were given five processes with their arrival time and execution time for each in the table. Process Arrival time Execution time Processes A 0 4 Processes B 2 3 Processes C 3 4 Processes D 5 5 Develop the schedule (time diagram) for the following methods. First-Come-First-Served (FCFS) Round Robin Shortest Process Next (SPN) Assume the length of the time quantum, or slice is 1 (q=1)

Your name must be on the timing diagram
