Computer is a mechanical device used for computing the jobs, mathematical problems, it is being used in many sectors from small scale to large scale.
History of Computers
The Concept of Computer lies in Abacus (a computing slate) 150 B.C. The word computer was enforced late 1600 AD. In 1837, the then renowned scientist Charles Babbage (known as father of computers) was the first man to design the computer with the concept of manufacturing unit (Inputing raw material, processing the raw material as per our requirement and turn the raw material into finished goods) by using programmable concept of computing. Basically the need of invention of computers started in late 1890, to process the data of census in United States of America. and the generation of computers started. Meanwhile many other scientist made efforts to design a user-friendly computing device. The actual era started after 1945. Categorically Computer History is divided into generations, each generations made computers relatively more familiar than previous generation. Lets take the journey by understanding each generation one-by-one.

The first computer was developed in mid on 20th century 1940-45, these computers consumed large amount energy, area, hundreds of people to operate the machine, it was built with the help of Vacuum Tube which use to produce large amount of heat and was not user friendly to operate. Vacuum Tube used to damage frequently. In this generation the concept was sucessful but the device was not useful.
