What are cables?

Cables are like secret highways that let electricity and signals travel from one place to another.

Imagine you have a toy phone, and you want to talk to your friend across the room. If there’s a cable connecting both phones, it’s like having a invisible rope that carries your voice from one toy to the other. That's how cables work, they help things like phones, computers, and TVs send messages or power all the way from where they’re made to where you use them.

How Cables Are Made

Cables are usually made of metal wires inside, wrapped in a plastic cover so they don’t get broken easily. Think of it like a chocolate bar, the metal is the candy, and the plastic is the wrapper that keeps everything safe. Sometimes cables have many wires inside, just like how some chocolates have lots of pieces.

Why We Need Cables

Without cables, your TV wouldn’t know what to show you, your phone wouldn’t ring when someone calls, and your computer might not even turn on! They're like the invisible friends that help all our favorite gadgets talk to each other.
