Imagine, a machine that doesn’t exist yet. Draw it in your notebook
                                    and write any one of its use.



                       DIFFERENCE BETWEEN COMPUTERS AND

                      MACHINES


                  Other machines can do, only the kind of work, for which they have been made. But
                  computers can do different types of work.

                  For example, we all have seen a bicycle. It is a machine. It is used for transportation
                  from one place to another. It makes our work easier but it cannot do anything other

                  than transportation. On the other hand, a computer can do a lot of things at the
                  same time. For example, we can draw a picture and listen to songs at the same time.

                         A computer cannot work on its own. It needs instructions to per-
                       form a task.
                         An abacus is also a machine. It has colourful beads which are used
                       for counting.




                      FEATURES OF A COMPUTER


                    1.  Computers work very fast and they don’t
                       make mistakes.

                                                                  information.
