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.


            PASCALINE CALCULATOR

            Pascaline calculator is the first mathematical calculator in the world. It was devised by a
            French mathematician. It used gears, dials and a series of rotating numbered wheels.
            Pascaline calculator was capable of performing only addition and subtraction.

            The first Pascaline calculator could perform calculations
            up to 5-digit numbers and the advanced series models

            were able to perform calculations up to 8-digit numbers.
