Topic Content:

  • The Stages of Development of Computers
  • Timeline (Summary)

The history of computing is as old as mankind. In the past, counting, and other simple arithmetic operations, were performed by the use of different kinds of objects such as fingers, toes, grains, pebbles, stones, sticks, drawing of lines and marks on surfaces, etc.

  • The concept of counting is believed to have been developed first by the herdsmen of ancient times, who sought methods of avoiding animal losses.

  • Quite a few people were involved in the development of the computer as we know it today. Many of the scientists, who made very useful contributions to the development of computers, did not really aim at developing the computer per se, but their inventions turned out to be extremely important to computer development. Computers were invented in 500 BC. It came into existence 3,000 years ago through Abacus – an aid to calculation, which is no longer in use today, except in China and the Middle East.
