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.
