How does Wi-Fi work to send data wirelessly?

Wi-Fi sends data through the air like a radio sends music to your car.

Imagine you have a toy phone that can talk to another toy phone across the room, without wires. That’s how Wi-Fi works, but with computers instead of toys.

When you click on a website or send a message, your router, like a special kind of radio, turns that information into invisible waves called signals. These signals travel through the air to your device, like a secret message being passed from one friend to another.

Your phone or computer listens for these signals and changes them back into something it can use, like turning music notes back into songs. That’s how you see pictures, hear sounds, and chat with friends all over the world, even when you're not connected by wires!
