   Syn: Contrivance; invention; design; scheme; project;
        stratagem; shift.

   Usage: -- Device, Contrivance. Device implies more of
          inventive power, and contrivance more of skill and
          dexterity in execution. A device usually has reference
          to something worked out for exhibition or show; a
          contrivance usually respects the arrangement or
          disposition of things with reference to securing some
          end. Devices were worn by knights-errant on their
          shields; contrivances are generally used to promote
          the practical convenience of life. The word device is
          often used in a bad sense; as, a crafty device;
          contrivance is almost always used in a good sense; as,
          a useful contrivance.
          [1913 Webster]

peripheral
device
peripheral device

    (Or "peripheral device", "device") Any part of a
   computer other than the CPU or working memory,
   i.e. disks, keyboards, monitors, mice, printers,
   scanners, tape drives, microphones, speakers,
   cameras, to list just the less exotic ones.

   High speed working memory, such as RAM, ROM or, in the
   old days, core would not normally be referred to as
   peripherals.  The more modern term "device" is also more
   general in that it is used for things such as a pseudo-tty,
   a RAM drive, or a network adaptor.

   Some argue that, since the advent of the personal computer,
   the motherboard, hard disk, keyboard, mouse, and monitor
   are all parts of the base system, and only use the term
   "peripheral" for optional additional components.
