The Free On-line Dictionary of Computing (30 December 2018):

hardware

    The physical, touchable, material parts of a
   computer or other system.  The term is used to distinguish
   these fixed parts of a system from the more changeable
   software or data components which it executes, stores, or
   carries.

   Typical computer hardware consists of electronic devices
   (CPU, memory, display) with some electromechanical parts
   (keyboard, printer, disk drives, tape drives,
   loudspeakers) for input, output and storage.  Completely
   non-electronic (mechanical, electromechanical, hydraulic,
   biological) computers have also been conceived of and built.

   See also firmware, wetware.
