Binary is the code computers use for just about everything, for all the information. It's all zeros and ones, and the computer interprets these digits to make us all very happy. Out of curiosity I found out my name in binary code yesterday and wrote it on the bottom of my shoe (because that's just the logical thing to do, right?
)
