0-F is just a different representation for the same thing: numbers. base10 uses 0-9. in computing a lot is about bits (0-1, base2) and bytes.
the great thing about hexadecimal (base16) is that you can represent every byte value with just 2 hex literals. eg:
FF = 255 = 1111 1111
0F =  15 = 0000 1111
F0 = 240 = 1111 0000

n, kk and vv are just placeholders for hex values. that means that you are supposed to replace these with real numbers in form of hex literals.

yes, it's called "MIDI Protocol". :)
