    - FIFO is an acronym for first in, first out

    - It is a method for organizing and manipulating a data buffer, where the oldest (first) entry, or 'head' of the queue, is processed first.

    - It is a comparable to processing a queue with first-come, first-served (FCFS) behaviour: where the people leave the queue in the order in which they arrive.
