Wireless networks work using radio waves instead of wires to transmit data between computers. That’s the simple version. If you’re curious to know what’s going on in more detail, then it’s all explained in this article.
Ones and Zeros.
I’m sure you know that computers transmit data digitally, using binary: ones and zeros. This is a way of communicating that translates very well to radio waves, since the computer can transmit ones and zeros as different kinds of beep. These beeps are so fast that they’re outside a human’s hearing range — radio waves that you can’t hear are, in fact, all around you all the time. That doesn’t stop a computer from using them, though.
Morse Code.
The way it works is a lot like Morse code. You probably already know that Morse code is a way of representing the alphabet so that it can be transmitted over radio using a dot (short beep) and a dash (long dash). It was used manually for years, and became a great way of getting information from one place to another with the invention of the telegraph. More importantly for this example, though, it is a binary system, just...
