FIFO (electronic)

In digital electronics, a FIFO (acronym for first-in, first-out) is a digital circuit that stores incoming data in internal memory and outputs the stored data in the order it was received. Data is stored on demand and the oldest stored data is output on demand, with both operations occurring independently and at potentially different rates. This is in…
