FIFO (First-In-First-Out) Algorithm

FIFO (First-In-First-Out) is an organizational method where the first item added to a system or queue is the first one to be processed or removed. Imagine a line at a grocery store checkout: the first person in line is served first. In data management or inventory, FIFO ensures that older items are used or sold before newer ones, helping to maintain order, reduce waste, and ensure freshness. This approach is common in inventory management, scheduling, and various queue systems to maintain fairness and efficiency.
