In computer science, multiple buffering is the use of more than one buffer to hold a block of data, so that a "reader" will see a complete (though perhaps old) version of the data, rather than a partially updated version of the data being created by a "writer".It is also used to avoid the need to use dual-ported RAM (DPRAM) when the readers and writers are different devices.

Applications. Buffers are often used in conjunction with I/O to hardware, such as disk drives, sending or receiving data to or from a network, or playing sound on a speaker.A line to a rollercoaster in an amusement park shares many similarities. People who ride the coaster come in at an unknown and often variable pace, but the roller coaster will be able to load people in bursts (as a coaster language agnostic - Buffered vs unbuffered IO - Stack Overflow UNIX buffered vs unbuffered I/O. 4.

Data buffer - Wikipedia

Managing Database Settings - Oracle The Essbase Kernel uses buffered I/O (input/output) by default, but direct I/O is available on the operating systems and file systems that Essbase supports, with the exception of Linux. Buffered I/O uses the file system buffer cache. Direct I/O bypasses the file system buffer cache and is able to perform asynchronous, overlapped I/Os. What Is a Buffer and How Does It Work?
