Stack vs Queue: LIFO vs FIFO Data Structures

Stack and Queue are basic topics, but they build the foundation of how systems actually work behind the scenes. Stack follows LIFO — the last thing you add is the first thing you remove. Queue follows FIFO — the first thing you add is the first thing processed. Once you understand these properly, a lot of real-world concepts like task scheduling, memory management, and request handling start making sense. Still learning by breaking concepts into real understanding instead of just memorizing them.
