GENERATIONS OF COMPUTER

GENERATIONS OF COMPUTER

FIRST GENERATION : ( 1946 – 1956 )

The computer of 1^st generation used vaccum tubes as the basic components for memory and circuitry for memory and circuitry for CPU .

These early computer used vaccum tubes as circuitry and magnetic drums for memory .

These computers of first generation were limited to solve  one problem at a time .

Input was based on punched cards and paper tape .Output came out on print out .

These generation computer general a lot of heat , sucked huge electricity .

SECOND GENERATION:  ( 1956 – 1964 )

Secondary generation of computer called Transistor computer .It is  a computer which uses discrete transistors instead of vaccum tubes .The 1^st generation of computer used vaccum tubes which generates large amount of heat were bulky .

There were big improvement over the vaccum tubes despite still subjecting computers to damage level of heat .

In comparison to first generation the size of second generation was smaller .

THIRD GENERATION : ( 1965 – 1971 )

The period of is roughly considered as the period of 3^rd generation of computers .

The third generation computers were developed by using the integrated circuit technology .

The third generation computer consumed less power and also generated less heat .

The computer system of the computer of the third generation was easier for commercial use.

The maintenance cost of the computer in the third generation was also low .

FOURTH GENERATION OF COMPUTER ( 1971 – 1985 )

The fourth generation computers were developed by using microprocessor technology .

In this generation , used very large integrated circuit ( VLSI ) VLSI having about 5000 transistors .

By coming to fourth generation computer became very small in size it became portable .

The machine of fourth generation started generating very low amount of heat .

FIFTH GENERATION OF COMPUTER ( 1985 – TILL NOW )

By the time , the computer generation was being categorized on the basis of hardware only but the fifth generation technology also included software .

The computer of 5^th generation had high capability and large memory capacity .

Some of the popular advanced technologies of 5^th generation include ,  Aritificial intelligent etc .
