telecommunication, a variable length buffer is a buffer into which datamay be entered at one rate and removed at another rate without changing the data sequence.
first-in first-out(FIFO) storagedevices are variable-length buffers in that the inputrate may be variable while the outputrate is constant or the output rate may be variable while the input rate is constant. Various clocking and control systems are used to allow control of underflow or overflow conditions.
