Hexadecimal.  Base-16 number system.  Goes from 00 to FF for a byte,
where 00 represents decimal 0, FF represents decimal 255.  In C-code
we represent those numbers as 0x00 and 0xff.

The number system goes 0 1 2 3 4 5 6 7 8 9 A B C D E F 10 11 12...

Computer science people live by hexadecimal, at least if they do
embedded programming.  Of course they used to use octal, where you
counted like this:

    0 1 2 3 4 5 6 7 10 11 12 13 14 15 16 17 20...
