Updated: 04/26/2017 by Computer Hope

Short for First In, First Out, FIFO is a method of processing data where the data first received is the first to be sent out after processed. Below is an example of how FIFO and LIFO would work. As can be seen in the picture, with FIFO the data is sent out in the same order it was received.
