Questions tagged [buffer]
A buffer is an area of memory set aside for temporary storage of data while it is being moved from one place to another. This is typically done to speed up processes with significant latency, such as writing to a disk, printer or other physical device. The output is ready to be sent to the device before the device is ready to accept it, so it is moved to the buffer so that the sending program does not have to continue waiting.
