Assertion (A): The convoy effect is a phenomenon primarily inherent to preemptive Round-Robin scheduling when the time quantum is extremely large.

Reason (R): The convoy effect occurs in First-Come, First-Served (FCFS) scheduling where many I/O-bound processes wait for a single long CPU-bound process

Choose the correct answer:

Explanation

Assertion (A) is False: The convoy effect is not primarily inherent to Round-Robin scheduling; rather, it is a classic drawback of First-Come, First-Served (FCFS) scheduling. While an extremely large time quantum in Round-Robin can cause it to behave like FCFS, the core phenomenon is fundamentally tied to FCFS.
Reason (R) is True: The convoy effect occurs in FCFS scheduling when multiple I/O-bound processes are forced to wait behind a single long CPU-bound process, resulting in poor resource utilization.
