a)Explain the turnaround time and response time.

b)Calculate the turnaround time and response time of each CPU scheduling algorithm (First-Come First-Served (FCFS), Shortest Job Next (SJN), and Round Robin (RR)).

(Assumption: Five processes arrive consecutively with the interval of 1 unit time)

(Time slice used for RR algorithm is 10 unit time)
