FIFO Queue

A FIFO (First-In, First-Out) queue is a way to organize items so that the first one added is also the first to be removed. Imagine a line at a checkout counter: the first person in line is served first. Similarly, in a FIFO queue, new items join at the end, and items are processed or removed from the front in the order they arrived. This method ensures fairness and order, making it useful in situations like task scheduling, messaging systems, or managing resources where processing happens sequentially.
