ISRO | ISRO CS 2013 | Question 49

Consider the following set of processes, with arrival times and the required CPU-burst times given in milliseconds.

Process  Arrival Time  Burst Time
   P1        0             4
   P2        2             2
   P3        3             1

What is the sequence in which the processes are completed? Assume round robin scheduling with a time quantum of 2 milliseconds
(A) P1, P2, P3
(B) P2, P1, P3
(C) P3, P2, P1
(D) P2, P3, P1

Answer: (B)
Explanation: The sequence in which the processes complete with round-robin algorithm with tq = 2 ms is P2, P1, P3

Option (B) is correct.
