What is chain?

A chain is like a row of links that are all connected together, so you can pull one and it moves them all.

Imagine you're wearing a bracelet, each little piece is linked to the next one. If you tug on one end, the whole bracelet moves. That’s how a chain works: each link holds on to the one before and after it, making them all move together when you pull.

Each part of the chain is called a link. They’re like little circles that fit around each other, just like how your bracelet fits around your wrist. When you put them all together, they make a long line that can bend and twist easily.

If you pull one end of the chain, it’s like giving a gentle tug to the first link. That link moves the next one, which moves the one after that, all the way down the line until the last link is moving too. It's just like when you're playing with a train: each car follows the one before it, so when the engine starts moving, the whole train goes!

Chains are used for things like bicycles, backpacks, and even jewelry, they’re super helpful in everyday life!
