“Bits, Bytes, Building With Binary If you work with computers (or even if you don’t!), there’s a good chance that you’ve heard people talk about computers as just ‘a bunch of ones and zeros’. This was one of the few things I knew about computers before I got into software: it’s all just ones and zeros. It was only after I learned to code and started programming professionally that I realized what that really meant. Yes, computers run on ones and zeros. It’s definitely a bit more complicated than that, but it’s not so complicated that we can’t understand it!
