what is a buffer used for
Typically, the data is stored in a buffer as it is retrieved from an input device (such as a microphone) or just before it is sent to an output device (such as speakers). However, a buffer may be used when moving data between processes within a computer. This is comparable to buffers in telecommunication.Buffers can be implemented in a fixed memory location in hardwareâor by using a virtual data buffer in software, pointing at a location in the physical memory.owever, a buffer may be used when moving data between processes within a computer.
