FIFO (First-In-First-Out) is a data structure where the first element added is the first one to be removed, just like a checkout line at Whole Foods. FIFO (First-In-First-Out) is commonly used in queues, buffers, and caches to ensure that data is processed in the order it was received, which is critical for things like message passing and event handling.
