A byte is not always 8 bits on old machines, though it is standardised as 8 bits nowadays.
This is why network RFCs talk of "octets", to avoid the ambiguity. Octets are always 8 bits.

(* technically, a 'foot' is not a standard unit of measure but that's due to the long history of 'foot' not being standardized until relatively recently)
