We know that a computer is a human-made machine. Have you wondered how a
                  computer works? In this chapter, we are going to learn how a computer works.

                  IPO Cycle                                                                                                                   2.


                  Have you seen your mother making mango shake for you? This is what she does to
                  make the mango shake.

                  1. She puts the mango pieces, sugar and milk in the blender. (This is the input.)                                                         Debit Card                  ATM Machine                       Cash

                  2. The blender mixes all the things. (This is the process.)
                                                                                                                                                                                                                  Information Literacy
                  3.  She pours the mango shake in the glass. Mango shake is ready to drink. (This is the                                                                                                         Interdisciplinary Learning

                  Similarly,  we  give  instructions  to  the  computer;  the  computer  then  works  on  the
                  instructions and gives us the result.
                                                                                                                                                  2.




                         The letters, numbers, symbols we give to the computer are called data.

                  computer is called processing and the result we get is called output.                                                     A computer is made up of many parts. These parts                   to make honey, computers

                  Thus, a computer works in three steps:                                                                                    are also known as devices.                                       gather information to help us
