                 EVOLUTION OF COMPUTERS

                 The modern computer has a long history of evolution. There have been major developments

                 in the field of computers since their invention.

                 The evolution of computers is a result of man’s search for fast and accurate calculating
                 devices. Some of the early calculation devices such as the Abacus, Napier’s bones, Pascaline
                 calculator  and Difference Engine have  played a  crucial  role  in  laying the  foundation  of
                 present-day computers. Let us discuss them in detail.


                 Abacus

                 In earlier times, people used bones, stones, and
                 pebbles to count and calculate. However, calculating
                 bigger numbers was a tough task through these

                 objects. To calculate bigger numbers, China invented
                 the first calculating device called the abacus.

                 Abacus consists of a frame that has rods with beads sliding through it. Calculations were
                 done by sliding these beads on the abacus.





                                            Napier’s Bones
                                            John Napier, a Scottish mathematician, created a manually-

                                            operated calculating device in  1617. This device used a set of
                                            rods with numbers written on them. These rods were carved out
                                            from bones, metals, woods or ivory. Napier's bones was named
                                            after the name of the scientist.
