-
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 the hardware is the 'heart' of a computer system, then the software is its 'soul'. Both are complementary to each other.
