SOFTWARE

                 Computer hardware cannot work by itself. It needs
                 step-by-step instructions to perform a task. These

                 stepwise  instructions are  called  software. You
                 cannot see and touch software. The games you play
                 on a computer are examples of software.

                 Let’s take another example:

                 You purchase a movie DVD. You can touch and hold the DVD.
                 But you cannot touch the movie stored in it. So, the DVD is the
                 hardware, and the movie in it is the software.

                 Types of Software                                                                         DVD

                 There are mainly two types of software:                               Software

                 1.  System software
                 2.  Application software
                                                                        System                         Application
                 System Software                                       Software                         Software

                 System software  controls  and manages  the overall  activities of a computer
                 system. So, the system software is like a manager of a computer system.


                 System software is a very important part of a computer system. Without it the
                 computer is like a car without a driver.

                 The main job of the system software is to prepare the computer for you to
                 work on and run application softwares. The Operating system is an example
                 of system software.

                 An operating system acts as an interface between the hardware components of a
                 computer and the user. It manages both computer hardware and software.

                 Microsoft  Windows  is the  most popular  operating  system available.  It  has
                 different versions like Windows XP, Windows Vista, Windows 7, Windows 8 and
                 Windows 10.
