Difference Between Spooling and Buffering in OS

In this post, we will understand the difference between spooling and buffering concepts in operating system −

Spooling

• It overlaps the input/output of a specific job with the execution of another job.

• It is more efficient in comparison to buffering.

• Buffering is less efficient than spooling.

• It can be expanded as ‘Simultaneous peripheral operation online’.

• Spooling considers the disk as a huge spool.

Buffering

• It overlaps the input/output of a specific job with the execution of the same job.

• It is a limited area in the main memory.

• It doesn’t have any expansion.

• It is less efficient in comparison to spooling.
