CUET PG 2026 — operating system os PYQ

List-I (Round Robin Configuration)

A. Quantum $\to \infty$

B. Quantum $\to 0$

C. Quantum > Longest Burst

D. Optimal Rule of Thumb

List-II (Resulting System Behavior)

1. Performance degrades to standard FCFS scheduling

2. High context-switch overhead; systems wastes time swapping

3. Behaves exactly like non-preemptive FCFS

4. 80% of CPU bursts should be shorter than the time quantum
