This scheme is mathematically correct.  Each binary digit has 
a value. From the right, the places are 1's, 2's, 4's, and 8's 
(which are 2 raised to the power 0,1,2,3).

The hexadecimal characters are 0 through 9 and A through F, 
associated with decimal values 0 through 15.  

Speaking, we may abbreviate hexadecimal to "hex".

There are two hex characters in a byte.  We one byte to contain 
a single ASCII character, like letters, punctuation, and 
digits 0-9.
