What is spooling in computing?

Spooling, which stands for 'Simultaneous Peripheral Operations On-Line,' is a process in computing where data is temporarily held to be used and executed by a device, program, or system. Most commonly, it refers to printing, where print jobs are stored in a buffer (the spool) before being sent to the printer. This allows the computer to continue working on other tasks while the printer processes the queued documents. Spooling helps manage tasks efficiently, especially when devices operate at different speeds.
