Who invented the binary code?

Wow I didn’t know some of this, it’s always great to know & remember the great minds that helped create the amazing world we live in today.

Some computer systems also use the hexadecimal based on system of sixteen numbers instead of two. They are: 0,1,2,3,4,5,6,7,8,9,A,C,D,E,F

LaContessa, you either understand binary, or you don't.

Another thing that baffled me in maths at school.
