EVOLUTION OF COMPUTER TECHNOLOGY

EVOLUTION OF COMPUTER TECHNOLOGY 
The origin of computer technology took place in the19th century. People desired to have a machine that would carry out mathematical calculations for them. The ABACUS is considered to have been the first computer in the world. It was used to perform simple measurements and calculations. ABACUS is available even today for school going children. In the 17th century, a scientist named Pascal developed a machine that could perform mathematical calculations. This machine comprised of a number
of gears. The movement of gear mechanism was used to perform somecalculations. He named the machine PASCALINE.
However, the concept of the modern computer was propounded by the scientist and mathematician Charles Babbage. He first wrote on the use of logic and loops in process execution. Based on the concept of logic and loops,Babbage envisaged two models for Computer Application in Management performing computations- Analytical Engine and Difference Engine. In those days, electronics was not developed. Therefore, these models proposed by Babbage existed only on paper. However, the ideas given by Babbage were  implemented after the invention of electronics.

George Boolean developed the famous Boolean Algebrabased on binary numbers. De Morgan put forward theorems on logic gates. These theorems are known as De Morgan’s Theorems. Lady Ada was the first computer programmer.
The real application of computers began in the latefifties. The computers were used in the United States for various applications such as census, defence, R&D, universities etc.
