In computer science‚ a buffer is a region of a physical memory storage used to temporarily store data while it is being moved from one place to another. 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 processeswithin a computer. This is comparable to buffers in telecommunication. Buffers can be implemented in a fixed memory
