As the time passed, the device of more suitable and
reliable machine was need, which could perform our work more quickly. During
this time, in the year 1946, the first successful electronic computer called ENIAC
was developed and it was the starting point of the current generation of
computer.
FIRST GENERATION
ENIAC
ENIAC was the world first successful electronic
computer which as develops by the
two scientists namely JP Eckert and
J.W Mauchy . It was the beginning of
first generation computer. The full computer and its weight was 30 tones. It
could store only limited or small amount of information initially in the first
generation computer the concept of vacuum tubes was used. A vacuum tube was such an electronic
component which had very less work
efficiency and so it could not work properly
and it required a large cooling system
SECOND
GENERATION
TRANSISTOR
As the development moved further,
the second generation computers knocked the door, in this
generation, transistors were used as the electronic component instead of vacuum
tubes. A transistor is much smaller in the size than that of a vacuum tube. As the size of electrons
components decreased from vacuum tube of transistor the size of computer also
decreased and it became much smaller than that of earlier computer
THIRD
GENERATION
INTEGRATED
CIRCUIT
The third generation computers
were invented in the year 1964 in this
generation of computer, I C (Integrated
Circuits ) was used as the electronic
component for computers. The development of IC gave birth to a new field of microelectronics.
The main advantage of IC is not only its small size but its superior
performance and reliability than the previous circuits. T.S Kiby first developed
it. This generation of computer ahs huge storage capacity and higher
calculating speed
FOURTH GENERATION
PERSONAL
COMPUTER
This is the generation where we
are working today. The computers which we see around us belong to the fourth
generation computers micro processor is the main concept behind this generation
of computer
A
microprocessor is a single chip (ls I circuit) which is used in a computer for
any arithmetical or logical functions to be performed in any program. The
honaur of developing microprocessor
goes tend Hoff of USA he developed first micro processor, the Intel 4004, as he
as working for Intel corporation, US.A
with the use of microprocessor in the fourth generation computers, the
size of computer become very fast and
efficient, it is evident that the next generation of computer i.e. fifth generation will be developed soon, in that
generation computer will possess artificial intelligence and it would be able
to take self decisions like a human being
