CHARLES BABBAGE’S ANALYTICAL ENGINE


                 In 1822, mathematician  Charles Babbage developed  a steam-
                 powered calculating machine, which he called the Difference Engine.
                 It has the size of an entire room. But even after working on this project
                 for 10 years, this machine never became a reality.


                                                                                                  Charles Babbage
                                                     In 1833, he invented a machine called the Analytical Engine,

                                                     the  first-ever working model  of a mechanical  computer,
                                                     a  fully program  controlled  machine.  This is  why Charles
                                                     Babbage is known as the Father of Computers.

                        LADY ADA LOVELACE’S PROGRAMS

                 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.

                        HERMAN HOLLERITH’S TABULATING MACHINE


                 Herman  Hollerith, an army engineer, built  a machine  called the
                 Tabulating Machine in 1890. The machine read and stored data from
                 punched cards.

                 After the success  of this machine,  Hollerith formed a  Computing
                 Tabulating  Recording  Company to  sell his machine.  Later in 1924,
                 his company became  a part of  International  Business  Machines                   Herman Hollerith
                 Corporation, today popularly known as IBM.
