what is buffering and what is spooling?

Answer 1

Buffering is a method of overlapping the computation of a job with its execution. It temporarily stores input or output data in an attempt to better match the speeds of two devices such as a fast CPU and a slow disk drive. If, for example, the CPU writes information to the buffer, it can continue in its computation while the disk drive stores the information.

With spooling, the disk is used as a very large buffer. Usually complete jobs are queued on disk to be completed later. A typical example is the spooler for a printer. When a print job is issued, the spooler takes care of it, sending it to the printer if it is not busy, or storing it on disk otherwise.

The main difference between buffering and spooling is that the latter allows the I/O of one job to overlap the computation of another. Buffering only allows the I/O of a job to overlap with its own computation

Answer 2

Spooling And Buffering

Answer 3

(buffering) Downloading the first block of data. In streaming media, buffering refers to bringing in an extra amount of data (filling the buffer) before playing the audio or video. Having more audio data or video frames in memory than are actually needed at each precise moment compensates for momentary delays in transmission from the source.(spooling) To store (data sent to a printer) in a buffer, allowing the program that sent the data to the printer to resume its normal operation.

Answer 4

Buffering refers to storing temporarily information into a memory zone (packets from/to the network, from/to a modem, etc). This is to optimize data processing.

Spooling refers to jobs sent to a printer. The jobs are saved in a location on some storage device, until the printer can process them.

Answer 5

It's things your printer does when its going to print.
