  • Input devices — keyboard, mouse etc.
  • Output devices — printer, monitor etc.
  • Secondary storage devices — Hard disk, CD, DVD etc.
  • Internal components — CPU, motherboard, RAM etc.

Relationship between Hardware and Software

  • Hardware and software are mutually dependent on each other. Both of them must work together to make a computer produce a useful output.
  • Software cannot be utilized without supporting hardware.
  • Hardware without set of programs to operate upon cannot be utilized and is useless.
  • To get a particular job done on the computer, relevant software should be loaded into the hardware
  • Hardware is a one-time expense.
  • Software development is very expensive and is a continuing expense.
  • Different software applications can be loaded on a hardware to run different jobs.
  • A software acts as an interface between the user and the hardware.
  • If hardware is the ‘heart’ of a computer system, then software is its ‘soul’. Both are complimentary to each other.
