ISRO | ISRO CS 2009 | Question 15
The performance of Round Robin algorithm depends heavily on
(A) size of the process
(B) the I/O bursts of the process
(C) the CPU bursts of the process
(D) the size of the time quantum
Explanation: In round robin algorithm, the size of time quanta plays a very important role as:
If size of quanta is too small: Context switches will increase and it is counted as the waste time, so CPU utilization will decrease.
If size of quanta is too large: Larger time quanta will lead to Round robin regenerated into FCFS scheduling algorithm.
So, option (D) is correct.
