Show answer & explanation
Correct answer: B
Spooling buffers data for devices operating at different speeds, commonly used to queue multiple jobs.
A printer is the classic example of a spooled device because it queues print jobs in memory while processing them sequentially.
In contrast, a terminal is an interactive device handling input in real-time rather than using spooling for job management.
