Buffer
An amount of memory which temporarily stores data to help compensate for differences in the transfer rate of data from one device to another. In CD recorders, the buffer helps to prevent buffer underruns. Buffer Underrun A buffer underrun occurs when your computer system cannot keep up the steady stream of data required for CD recording. The CD recorder has an internal memory buffer to protect against interruptions and slowdowns, but if the interruption is so long that the recorder's buffer is completely emptied, a buffer underrun occurs, writing stops, and most often the recordable CD is ruined.
