A special software to create a job queue is called –

The term SPOOL stands for Simultaneous Peripheral Operations On-Line.

• The Problem: CPUs are much faster than printers or disk I/O. If a CPU had to wait for a printer to finish one job before starting the next, the system would be incredibly slow.

• The Solution: A Spooler is a software component that intercepts these jobs and places them into a job queue (usually on a disk). The CPU "dumps" the data into the queue at high speed and moves on to other tasks, while the spooler slowly feeds the jobs to the peripheral device one by one.
