A bit more complex. With ripping DVDs there’s a big prime number that’s used to encrypt. Here is a Good video on the situation. Similarly though it is all modulated voltages at the end of the day. The number or really any number is just some particular pattern of voltages or magnetic poles or really anything you can modulate. The first computers were completely mechanical. Well technically speaking the first computers were people with pencils and paper.
So basically just like with DVD players.
