What are binary signals?

Binary signals are like using just two colors to send messages, and that’s all you need!

Imagine you and your friend are playing a game where you can only use red or blue lights to talk to each other. If the light is red, it means “yes,” and if it's blue, it means “no.” That’s how binary signals work, they use just two options, like 0 and 1, to send information.

Think of a flashlight in your hand. When you turn it on, that's a 1, and when you turn it off, that's a 0. If you flash the light on and off quickly, on, off, on, off, you're sending a message using binary signals!

Computers use this idea too! Inside your tablet or phone, everything is made up of tiny switches that can be either on (like the flashlight) or off. These switches send messages using 0s and 1s, which are like binary signals, simple but powerful! Binary signals are like using just two colors to send messages, and that’s all you need!
