History of Computers
Man has always been making efforts to evolve better methods
of counting and computing to make his life easier. Initially mechanical devices
were developed to make counting simple. This was followed by electronic devices
and now we have very sophisticated electronic devices known as computer to do
this work for us. The history of computers, which is long tale, here we will
discuss in brief.
Counting with Fingers And
Pebbles
This is the ealiest method of counting which we use even
now. Our ancestors did not have any computing
machines , so they used to count with help of stones and with fingures.
Abacus
The Abacus (G.K. Abacus ) means board or calculating table.
This device was first invented by Egyptian in 450 B.C. Later it was the first
mechanical calculating device. Abacus consisted of a rectangular wooden frame ,
having iron rods. A divider with coloured beads in rows was used for
calculating and beads effect the value of the number. The beads are moved
according to certain rules in order to
solve problems of calculating . A skilled abacus operator can add up numbers
faster than a modern calculator.
