Ummm, two nybbles is a byte, not a word. A word is two bytes, not one byte.
Base 10(decimal) is 0123456789
Base 16(hexadecimal) is 0123456789ABCDF
In hex, one character= the less herd of NYBBLE.
Ther are 4 bits in a nibble and 2 nibbles in a BYTE(or 8 bits)
a collection of bytes is called a WORD
FF is an 8 bit word (2 nibbles) which is (16x16=256)-1(for zero)=255 (256 possible numbers inc. 0)
FFFF is a 16 bit word made up of 2 bytes (or 4 nibbles sometimes called long)
therefor (16x16x16x16 or 256x256=65536)-1(for zero)=65535
