i + COMPUTER SOFTWARE
A computer is an electronic machine. It cannot work by itself. A computer needs instructions
to do anything. These step-wise instructions are called software.
Software works like a manager between computer hardware and humans. So, we can say
that the part of a computer that we cannot see and touch is known as software.
For example, you play a movie on the computer from a pen drive. You can touch the pen
drive but you cannot touch the movie. The movie is a software and the pen drive is the
hardware which stores the movie and keeps it safe.
There are two types of software: System software and Application software.
Software
System Software Application Software
System Software
A software that controls and manages all the activities of a computer system is called
System software. The system software is like a manager who manages a computer system.
When we switch on a computer, the first thing that system software does is to prepare
the computer for you to work on it. It loads important files so that you can work and run
the application software. This software is called the Operating System.
