Some people don't think that the base 10 system is very good.
What do they think would be better?
Surely not binary...

Why Binary?
So, we understand that computers use 1's and 0's; but why?
why-binary.mp4Information theory is about studying the transmission, processing, extraction, and utilization of information. Abstractly, information can be thought of as removing uncertainty.
Let's hear a bit more about information in general.

Encoding
When we convert information to be able to store it or transfer it through another medium, we call this encoding. Written language is the encoding of our spoken language. If you recall, all letters on the computer (at the lowest level) are actually numbers, which are represented as binary (again, if we're at the lowest level).
So, the letters of the alphabet are encoded to binary if you get down to the base level.
Let's look a bit more at that.
