In a time-sharing system, what can happen if the time quantum is too large?

Options

  • A. The system behaves more like First-Come, First-Served scheduling
  • B. Every process executes simultaneously on a single CPU
  • C. Context switching becomes impossible
  • D. All processes are automatically terminated
  • E. None of the above

Correct Answer (Detailed Explanation is Below)

A. The system behaves more like First-Come, First-Served scheduling

Detailed Explanation

Explanation: If the Round Robin time quantum becomes very large, each process may run for a long time before switching. The scheduling behaviour approaches First-Come, First-Served (FCFS), reducing interactive responsiveness.
