 The History of computing
*3000 B.C. : The Abacus
     *The original mechanical counting device.
   

*1623-1662 : Blaise Pascal
     *French mathematician and philosopher
     *Built the pascaline in 1642
                    

*1642: The Pascaline
     *a counting wheel design

                                     

*1801 : Jacquard's Loom

      *French,an Joseph Marie Jacquard (1753 -1871)
      *Wearing Loom
      *The first significant use of binary automation

                                    

*1793 -1871 : Charles Babbage

      *Envisioned a steam -powered difference engine and then an analytical engine.
                                            

*1816 - 1852 : Lady Ada Augusta Lovelace

     *Punched cards could be prepared instruct babbage's engine to repeat certain operations
     *The first programmer

                                           

*1842 : Babbage Difference Engine and the analytical engine
                                             

*1860 - 1929: Herman Hollerich
      *Devised a punched-card tabulating machine to speed up the 1890 US census
                                                      

*1890: Holerith's Tabulating Machine
       *Used a hand punch to enter data onto cards
       *A panthograph punch
*1974 -1956: Thomas Watson Sr.
     * In 1896 Herman Hollerich founded the tabulating machine company
     *form the computing - tabulating recording company

     *renamed the International Business Machines Corporation(IBM)
                                    

*1920's-1950's: The Electro - Mechanical accounting machine      *punched card technology
