Stack

A stack is a way of organizing information where items are added and removed in a specific order, called "last in, first out" (LIFO). Think of it like a pile of plates: you put new plates on top and remove the top plate first. In computing, a stack stores data temporarily, allowing programs to keep track of tasks, function calls, or data needed temporarily. It’s a fundamental concept used in programming and system operations to manage data efficiently and in a controlled manner.
