It’s time for Santa and Elves and if we keep playing with our imagination let us look to the online world. If we imagine a big microscope that can look behind web pages, codes and stuff we could probably see the smallest parts of the digital universe. And the smallest parts are just two numbers: 0 and 1. That’s the binary numeral system which represents numeric values using two different symbols: typically 0 (zero) and 1 (one). Each digit is bit.
