There are several different places that a buffer cache can exist. All have the one thing in common - they are places where data being read from or written to a device is temporarily stored in some medium that is faster than the backing device.
In the case of read caches, a buffer cache can store frequently requested data on a medium that is considerably faster than the underlying device, which speeds up the return of that data to the requesting program. It can also be used to assemble data received out of order (such as from a network interface) into a more presentable form, or can be used to assemble asynchronous data into fixed-size chunks for processing.
In the case of write buffer caches, they are used to smooth out small I/O writes into larger streaming writes (which provides better write performance). They can also be used to assemble smaller bits of information into a larger packet for transmission out a network interface.

What is the difference between unix operating system and Linux operating system?
Linux is a Unix-like system. This means that it is inspired or influenced by Unix in some shape or form (Linux started off from Minix), but it is not directly derived from Unix. However, BSD is based on Unix, and macOS is indirectly Unix-based because of its mixed heritage with BSD.
Is UNIX used primarily with mainframes as a network operating system?
No. Licensed Unix implementations are a proprietary flexible general purpose operating system originally marketed for minicomputers and mid-range computers to support multiple users and tasks. When Personal Computers became available, versions of Unix were created for them. Unix was also implemented for the IBM mainframe. This is not the same as Linux which is an open source free system with many of the same capabilities and look & feel of unix but without the licensing requirement of unix.
Which are the five most commonly used operating systems in banks?
Most of the BANKS works on Mainframes which generally uses UNIX operating systems. But a BANK can use UNIX and flavours of LINUX (which is a UNIX flavor) and Windows Server ...
What is LUnix?
LUnix (unofficially, Little Unix) is a Unix-like operating system for the Commodore 64, a popular home computer of the 1980s.
What is the difference between UNIX and other operating system?
Unix is a multi user, multi processing and multi tasking operating system
Is Buffer cache is hardware entity?
I think No. Because buffer cache is a part of kernel and kernel is a software entity thats why buffer cache is also a software entity. However the buffer and the cache both are hardware entity separatly.
What are the advantages and diadvantages of a buffer cache?
A cache allows one to retrieve commonly used information very quickly (if it is still in the cache) rather than trying to find it on the system (which takes much longer). The disadvantage is that is takes away memory from the system to implement the cache.
What is kept in the Database Buffer Cache?
Database Buffer cache is one of the most important components of System Global Area (SGA). Database Buffer Cache is the place where data blocks are copied from datafiles to perform SQL operations.
What is a buffer called when it is reading a ram or a drive?
Cache
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.

What does the cache(8 meg) mean or do for a for a hard drive?
The cache size is refers to the size of buffer on the hard drive. The bigger the the buffer, the less the hard drive has to access the drive. Also it improves the time that the computer needs to access data from the drive.
What are the Advantages and disadvantages of cache mapping techniques?
Advantages:1) Faster memory access2) Higher CPU UtilizationDisadvantages:1) Cost Factor2) Cache coherency
What do you call the memory in an input or output device?
Typically Storage. But it can also be called Cache, Buffer, or RAM
What is a data burst cache?
It term used to describe the typical 8, 16, or 32-MB of disk cache in the hard drive that acts as a buffer between the drive andcomputer system.
High speed storage areas that temporarily store data during processing are called?
registers cache buffer
What is the purpose of the cache?
Cache is a special kind of memory which is can be used as a spare to store data
