Buffer Memory

A buffer is essentially a short term data storage facility used to accommodate variable data read or write periods, temporarily storing data in sequence until it can be processed by, or transferred to, some other part of the system. In the case of a DAW Interface, the buffer allows the computer to handle other background processes while audio samples flow in or out of the buffer at a constant rate. The size of the buffer determine the latency of the interface, so the general rule of thumb is to keep the buffer as small as possible (without generating clicks or errors) while recording, but as large as possible (to give the computer maximum processing time) when playing back.
