Answers
Explanation:
First generation computers
The first generation computers existed in 1940 to1956 with ENIACdeveloped by J.Presper Eckert and Johu Mauchly.in the USA by using vaccum tubes.It was based on machine and high level language.
Second generation computers
The second generation computers existed from 1956 to 1963.It used transistors which increase their performance.The size get decreased.Some languages like COBOL are used.UNIVAC and LEO are examples of second generation conputers.
Third generation computers
The third generation computers existed from 1963 to 1971.It used Integrated Circuit which increase their performance. They used languages like RPG and the speed increased into nanosecond.This generation led to the invention of main frame computers.Examples of this generation are IBM 360 andHoneywell-200.
Forth generation computers
The forth generation computers started from 1971 to 1985 and used microprocessor to work.Presently the 'i-core'series was considered as the most powerfulmicroprocessor . IBM,APPLE,HCL,LENOVO etc are examples. Languages like SQL were used.
Fifth generation computers
This computers are based on present and future. However scientist were working to produce intelligence to the computers . These computers will be based on Artificial Intelligence.
