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.

Spooling is better than Buffering all the way... In Spooling,CPU Allows overlap of one Job with the computation and output of other job...whereas in Buffering,the CPU overlaps input,output and processing of a single Job. (Job = Program)
Even in a simple system,the spooler may be reading the input of one job while printing the output of a different job.

Cache stores frequently accessed data in a temporary storage location to speed up access times, while spooling is a process that temporarily stores data to a disk or queue before it can be processed or printed, such as in a printing queue. Cache improves performance by reducing the need to access the original source, while spooling helps manage the order and timing of data processing.
A spool is just something you keep sting and such on. Spooling is doing something with that said string or wool.

What is the relation between the path difference and phase difference?
The phase difference between two waves is directly proportional to the path difference between them. The phase difference is a measure of how much the wave has shifted along its oscillation cycle, while the path difference is a measure of the spatial separation between two points where the waves are evaluated.
What is the difference between 164 and 220?
The difference between 164 and 220 is 56.
Define the 'potential difference between the ends of a conductor'?
Potential difference between the ends of a conductor refers to the electrical energy difference per unit charge between two points in the conductor. It is commonly known as voltage and is measured in volts. A potential difference is necessary for the flow of electric current in a conductor.
How much is the potential difference between the terminals of a connection wire?
The potential difference between the terminals of a connection wire is determined by the voltage difference applied across the wire. This voltage difference creates an electric field within the wire that causes charge carriers to move and establish a potential difference between the terminals.
What is the difference between the lowest temperatures?
The difference between the lowest temperatures refers to the numerical value that represents the interval between the two lowest recorded temperatures. It is the result of subtracting the lower temperature from the other to determine their difference.
What is the difference between online spooling and offline spooling?
in off line spooling user has no interface with systems it strongly used in Batch system's.it mean's that you submit your request to system , system will cmputing and print result of request without interface with user.
What are difference between cache database and sql database?
CACHE is multidimensional and postconsonantal database and its supporting scripting
What is the difference between 6m L2 cache and 3m L2 cache?
Dildo's...S......So many Dildo's
What is the difference between cache-memory and primary-memory?
Cache memory is smaller and quicker, primary memory larger and slower.
What is the difference between cache memory disk cache?
memory cache is on memory RAM, disk Cache is on the hard drive. They make things to get faster. For instance Google Earth use this disk cache to show you offline images.
Difference between spooling and buffering?
Spooling is an acronym for Simultaneous Peripheral Operation On-Line and involves placement of data in temporary working area for another program to process. Buffering on the hand, is preloading data into a reserved area of memory which is called the buffer.
What difference between 32MB cache buffer and 64MB cache buffer?
A megabyte is a unit of information storage equal to 8,388,608 bits. The cache buffer is an area of extremely fast-access memory used by the processor, so the larger the area, the more data could take advantage of this speed. The "difference" between the two is self-evident.
Why is spooling necessary for batch programming?
advantage of spooling
What is the difference between cache memory and primary memory?
they are both different so stop asking dumb questions
What is the difference between the locations of discrete L2 cache and advanced transfer cache?
On-Package L2 cache (discrete L2 cache) is on a separate microchip within the processor housing, while Advanced Transfer Cache (ATC) is located directly on the same die as the processor core.
Sending print jobs to a buffer instead of immediately to the printer?
Spooling
What is the difference between cache vs cold cache vs hot cache vs warm cache vs cache hit vs cache miss?
Firstly, it sounds like you are asking for general definitions, rather than differential definitions, which is problematic when the definitions are differential and context specific. Cache miss: not in cache, must be loaded from the original source Cache hit: was loaded from cache (no implication of what "type" of cache was hit). cold cache: The slowest cache hit possible. The actual loading mechanism depends on the type of cache (CPU cache could refer to an L2 (or L3) hit, disk cache could refer to a RAM hit on the drive, web cache could refer to a drive cache hit) hot cache: The fastest cache hit possible. Depends on mechanism described (CPU could be L1 cache, disk could be OS cache hit, web cache could be RAM hit in cache device) Warm cache: Anything between, like L2 when L1 is hot and L3 is cold. It is a less precise term and often used to imply "hot" when the performance is closer to "cold."
