Definition of Computer 

A computer is a machine or device that performs processes, calculations and operations based on instructions provided by a software or hardware program. It is designed to execute applications and provides a variety of solutions by combining integrated hardware and software components.

History of Computer 

Generations of computer 

Generation of computer in computer term is a change in technology a computer was being used. Initially, the generation term was used to distinguish between varying hardware technologies. But now days, generation includes both hardware and software, which together make up an entire computer system. There are totally five Generation of computer known till date. Each generations of computer has been discussed in detail along with their time period, advantages, disadvantages and examples. We have used approximate dates against each generation which are normally accepted.

Types : Generation of Computer 

First Generation (1940 to 1956) 
Second Generation (1956 to 1963) 
Third Generation (1964 to 1971) 
Fourth Generation (1971 to 1980) 
Fifth Generation (Present Time) 

First Generation of Computer 

The beginning of commercial computer age is from UNIVAC (Universal Automatic Computer). It was developed by two scientists Mauchly and Echert at the Census Department of United States in 1947. The first Generation of computer were used during 1940-1956. They were based on vacuum tubes. Examples of first generation of computers are ENIVAC and UNIVAC-1.
