Computer Science (Coding)

We use computers every day! But they see the world a little differently from us. They see the world in BINARY - a system of numbers made up only of ones and twos. Why do they do this? It's much faster for computers to count and do math using binary numbers!

Have you ever wanted to send an encoded message that only a handful of people could actually decode? This conversion tool will take any text string and convert it into binary code.

Learn how a stream of 1s and 0s to represent all of our data - from our text messages and photos to music and webpages.
