download

download vt.  To transfer data or (esp.) code from a
   larger `host' system (esp. a {mainframe}) over a digital
   comm link to a smaller `client' system, esp. a microcomputer
   or specialized peripheral.  Oppose {upload}.

   However, note that ground-to-space communications has its own usage
   rule for this term.  Space-to-earth transmission is always `down'
   and the reverse `up' regardless of the relative size of the
   computers involved.  So far the in-space machines have invariably
   been smaller; thus the upload/download distinction has been
   reversed from its usual sense.
