A quick detour to binary You probably know that everything computers do, they do in binary (zeroes and ones) under the hood. But how does that actually work? Binary is just another numbering system like decimal (there are many others!), so while with decimal each digit can have 10 different values (0-9, hence decimal), numbers represented in binary have 2 possible values (0-1, hence binary). In binary a digit is called a bit.
