What is the main tradeoff when choosing a smaller versus larger time quantum in Round Robin scheduling?
Correct! Well done.
Incorrect.
The correct answer is D) A smaller quantum improves responsiveness for interactive processes but increases context-switch overhead, while a larger quantum reduces overhead but makes the system behave more like FCFS
Correct Answer
A smaller quantum improves responsiveness for interactive processes but increases context-switch overhead, while a larger quantum reduces overhead but makes the system behave more like FCFS
Each context switch has a fixed overhead cost. A very small quantum spends a large fraction of CPU time switching contexts, while a very large quantum makes Round Robin degenerate toward FCFS, hurting interactive response time. A good quantum is typically chosen so most interactive bursts complete within one slice.
