Relationship between Hardware and Software

  • Mutually dependent. Both of them must work together to make 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 softwares 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.
