"Little endian" means "the little end comes first" (with "the little end" referring to the least significant byte). See http://en.wikipedia.org/wiki/Endianness#Etymology for the origins of the term.

Endianess is defined in terms of byte-addressable memory. Software running on such an architecture would have to emulate the behaviour of a little or big endian byte-addressable architecture when exchanging data with the outside world.
