How does the internet actually work, from device to server?

The internet is like a big group of friends passing messages to each other so they can share stories and toys.

Your device, like your phone or tablet, is like you, it wants to talk to a server, which is like the friend who has all the cool toys and stories. To start talking, your device sends out a message through the internet, which is like a long hallway with many doors and windows that help messages travel from one place to another.

When you tap on an app or click a link, your device sends a message saying, "Hey, I want to talk to you!" This message goes through routers, special helpers who direct the message down the right path. Routers are like traffic cops who make sure everyone gets where they need to go.

Finally, the message reaches the server, which replies with what you wanted, like a toy or story. Then it sends the reply back through the same hallway and into your device, so you can see or hear what was shared.

It's just like passing notes in class, but way faster and more fun!
