Generation of computer
Charles
Babbage invented Analytical engine & Difference engine where he used memory
for storing. This was the starting of a new era of computer field. Because of
that Charles Babbage is known as the father of computer.
UNIVAC-I
was the first ever made commercial computer. Full form of UNIVAC is- Universal
Automatic Computer, developed by J. Prosper Eckert and John Mauchly.
Changes
were also seen in the computer over time. These changes are known as
generation. There are mainly five generation of computer.
First
Generation (1946-1959) -- Computers of first generation are mainly used
for calculation. In these computer Vacuum Tubes were in use. Vacuum tubes were
very large in shape & they generate lots of heat. They are also very
expensive.
Second
Generation (1959-1965) -- In this generation, makers use
Transistors that make computer faster to first generation. Now computers are
capable to operate other functions. They are also big in size &
expensive.
Third
generation (1965-1970) -- In this generation, IC’s (Integrated
Chips) were in use. They make computer faster. These computers were used in
scientific, commercial, programming and other functions. Programming languages
COBOL, FORTRAN, BASICS are used in this era. There was significant change of
size & cost of these computer.
Fourth
Generation (1970-1980) -- This generation is known as VLSI (Very
Large Scale Integration) technology. Here makers use a micro-processor in
computers. The size & cost was lesser than third, second, first generation
computers.
Fifth
Generation (1980-NOW) -- This generation is known as ULSI (Ultra
Large Scale Integration) technology. In this generation we are using AI
(Artificial Intelligence). Now computers can use their own IQ (Programming) for
solving problem. These computers are also called knowledge Information
Processing system.
