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. This movie is the software and the pen
drive is the hardware which stores the movie and keeps it safe.
