Show answer & explanation
Correct answer: A
Spooling stands for Simultaneous Peripheral Operations On-Line, managing data transfer between devices at different speeds. A line printer is the classic example because print jobs are queued in a buffer on disk before printing. This allows multiple users to submit requests simultaneously without waiting for the physical device, making it a spooled device.
