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.
