little-endian

little-endian adj.  Describes a computer architecture in
   which, within a given 16- or 32-bit word, bytes at lower addresses
   have lower significance (the word is stored `little-end-first').
   The PDP-11 and VAX families of computers and Intel microprocessors
   and a lot of communications and networking hardware are
   little-endian.  See {big-endian}, {middle-endian}, {NUXI
   problem}.  The term is sometimes used to describe the ordering of
   units other than bytes; most often, bits within a byte.
