Answer / pooventhan elango
Acronym for simultaneous peripheral operations on-line,
spooling refers to putting jobs in a buffer, a special area
in memory or on a disk where a device can access them when
it is ready. Spooling is useful because devices access data
at different rates. The buffer provides a waiting station
where data can rest while the slower device catches up.
The most common spooling application is print spooling. In
print spooling, documents are loaded into a buffer (usually
an area on a disk), and then the printer pulls them off the
buffer at its own rate. Because the documents are in a
buffer where they can be accessed by the printer, you can
perform other operations on the computer while the printing
takes place in the background. Spooling also lets you place
a number of print jobs on a queue instead of waiting for
each one to finish before specifying the next one.
