Grading for this question was broken down into the following:
- Explanation of round-robin scheduling: 5 points. You lost a point
if you did not mention that a hardware timer interrupt is necessary.
- Strengths of round-robin scheduling: turnaround/waiting time. 2 points.
- Weaknesses of round-robin scheduling: context-switch overhead,
does not really approximate SJF, 80% of processes should expire before
the time quantum. If you mentioned one of these, you got a point.
If you mentioned two or three you got two points.
