Consider the 5 processes described below: Process Pi P2 P3 PA P5 Arrival Time 0 1 3 4 5 CPU Time 5 4 2 3 2 a. (5 points) Draw a timing diagram showing when each process executes under FIFO. b.(5 points) Draw a timing diagram showing when each process executes under SJF (use FIFO as tie- breaker if necessary). c. (5 points) Draw a timing diagram showing when each process executes under SRT (use FIFO as tie- breaker if necessary). d. (5 points) Draw a timing diagram showing when each process executes under Round-Robin (use Q =4). e. (5 points) Find the average turnaround time of all processes in each of the previous parts
