What is stack?

A stack is like a tower of plates in a kitchen, you add one on top, and you take one from the top.

Imagine you're helping set the table. You start with an empty plate rack. When you want to add a plate, you put it on top of the stack. If you need a plate, you always take the top one first, that’s how we use plates every day!

Stacks work the same way in computers. When a computer is doing something, like running a game or opening a file, it uses a stack to keep track of what needs to be done next.

Think about stacking your toys, you put one on top when you're playing with it, and take one off when you're done. A stack in computer land does the same thing:

• When something happens, it goes on top of the stack (like adding a plate).
• When that thing is finished, it gets taken from the top (like taking a plate).

This makes sure everything happens in order, just like your plates stay neat when you use them right! A stack is like a tower of plates in a kitchen, you add one on top, and you take one from the top.
