                  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.
