What do you mean by Spooling

Question

What do you mean by Spooling? Describe in brief.

Answer 1

A spool (Simultaneous Peripheral Operation on Line) is a buffer which holds output for a device, like a printer which can’t accept interleaved data streams. Spooling is a method in which secondary storage is employed to spool the output files as a queue. The spooling system copies the queued spool file to the printer, one at a time. Therefore, spooling is a method to decrease speed mismatch and intern, the idle time of CPU.
