1. Apply the following scheduling algorithms to the list of processes above.
First-Come First-Serve
• Shortest Remaining Time First
Round Robin: Quantum = 3
2. For each process scheduling algorithm, provide the following:
a. A complete and detailed table that contains the following criteria for each process
o Finish time
o Turnaround time
o Waiting time
b. A detailed Gantt Chart
c. The average turnaround time
d. The average waiting time
3. Then, answer the following items
a. Among the three (3) process scheauling algorithms that you have performed, which do you
think is the most efficient and why?
b. Cite significant differences in the results of applying the First-Come First-Serve algorithm and
Round Robin algorithm. Elaborate on your answer.
c. What could possibly happen if the value of the Quantum in Round Robin is increased to 5?
Elaborate on your answer.
d. In your opinion, why does the average turnaround time and waiting time vary per algorithm?
e. Would you suggest the utilization of the Round Robin algorithm for process scheduling in a file
management system? Why or why not?
