what is a computer:
The computer is electronically machine that is used to accept data, processed data and store it for later used.
the computer is consist of hardware and software.
Hardware: hardware is the physical part of the output computer which user can see and touch
e.g. keyboard mouse, printer scanner etc.
Software: are the intangible parts of the computer. which user can just see and touched.
the relationship of the hardware and software is that the computer can not work without hard and software, e.g. if you have a window operating system and you don't have any input device and output device then you cannot be used your computer efficiently.
because the operating system is software and the input-output device is hardware.
