Tasks

1.What is the average waiting time if SJF with preemption algorithm is used? Use "Arrival time" column.

2.What is the average waiting time if nonpreemptive priority algorithm is used? Use "Priority" column.

3.What is the average waiting time if RR (quantum = 1) algorithm is used? Ignore the arrival delay.

4.What is the average waiting time if RR (quantum = 2) algorithm is used? Ignore the arrival delay.

5.What is the average waiting time if processes arrive in the reverse order (P5, P4, ... , P1) and RR (quantum = 2) algorithm is used? Ignore the arrival delay.

6.What is the average waiting time if RR (quantum = 4) algorithm is used? Ignore the arrival delay.

7.What is the average waiting time if processes arrive in the reverse order (P5, P4, ... , P1) and RR (quantum = 4) algorithm is used? Ignore the arrival delay
