If you are reading this on a device right now, you're probably using the internet!

Have you ever thought about how the internet works?

Imagine the internet to be like a giant constellation of stars!

They are constantly chatting to each other, exchanging and sharing information across the skies.

These machines talk to each other in 'programming language' that look like a bunch of random letters and numbers to us! 

Servers are helpful machines that make the internet work for us. 

Servers can quickly sort through information to get the best answers when you ask a device a question.

They make sure the right messages get sent directly to you and not to your neighbour by accident!

Information travels across the internet in two ways...

2. Through overhead satellites

Did you know...?

There are 20.4 billion devices connected to the internet!

That means there are all kinds of characters online, which is why it's important to learn how to protect ourselves online.
