What are ones and zeros?

Imagine you have just two favorite toys, a red ball and a blue block, and those two are all you need to play your favorite game.

Ones and zeros are like that, they’re the simplest way to talk about anything in the world of computers. Just like your red ball and blue block, ones and zeros are just two choices, but with them, you can make up everything from a song to a picture.

Think of it like counting on your fingers. If you have one finger up, that’s a one; if it's down, that’s a zero. Computers use this same idea, they turn everything into groups of these two numbers.

Computers understand only the simplest things, just on or off, like a light switch. A one means "on" and a zero means "off." So, when you watch a video on your tablet or play a game, it’s really just a bunch of these ones and zeros working together, switching on and off super fast!
