It was capable of solving any mathematical problem and storing
                 data in an indefinite memory. This is why Charles Babbage is

                 known as the ‘father of computers’.


                 LADY ADA LOVELACE’S PROGRAMS
                                                                                                   Analytical Engine
                 The instructions given to Babbage’s Analytical Engine were in

                 the form of 0s and 1s and the first person to introduce this concept
                 was Lady Ada Lovelace. Since she was the first to introduce the
                 concept  of  programming,  she  is  known  as  the  first  computer

                 programmer.

                                                           Magnetic tapes were used to store data
                  Second Generation  (1950s)               Small in size and less expensive than
