When you are buying a computer you just buying a Hardware components only. This system is just like skeleton of Human without skin. It is not useful in any way and they won't perform any functions independently. If the Human body with skin then it can do any work that is not done by skeleton. Thus the skin makes skeleton into functioning.

         Similarly, To work with Hardware of your computer components you need software. The system hardware can't perform any operations independently on its own. The software that is used to do work with hardware is called system software. The best example of system software is an " Operating System".

What is an operating system ?

                                 An operating system is a system software which acts as a middle ware between user and hard ware. It provides an interface to run application programs.

The main function of operating system includes 

  • providing interface between computer hardware and users 
  • provides a platform for running different application software 
  • manages the computer memory and programs run in it
  • provides security for your data
  • provides basic data manipulation methods

Where I get operating system for my computer ?

                                                   Generally there are two ways for getting software for your computer. The first and frequently most of the peoples used is downloading trial versions from the internet. Secondly you also buy the Pro Versions from the companies like Microsoft Window.
