[Cami]

1. A piece of hardware that encapsulates some function but cant be
   used without some kind of front end. Today we have,
   especially, print engine: the guts of
   a laser printer. 2. An analogous piece of software; notionally, one that does a lot
   of noisy crunching, such as a database
   engine.The hacker senses of engine are
   actually close to its original, pre-Industrial-Revolution sense of a skill,
   clever device, or instrument (the word is cognate to
   ‘ingenuity’). This sense had not been completely eclipsed by
   the modern connotation of power-transducing machinery in Charles Babbages
   time, which explains why he named the stored-program computer that he
   designed in 1844 the Analytical
   Engine.
