GENERATIONS OF COMPUTER

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
