HISTORY OF COMPUTER:

First Generation - (1945-1955)
• The computers, ENIAC , EDVAC , UNIVAC and Mark (one)1 covers the primary section of development of pcs belong to the first generation of computer.
• This instrumentality is created ​​"between" 1945-1955 .
• The computers developed in first generation used vacuum tubes.
• devices These devices were quicker calculation time . However, the memory size of those computers was restricted.
• They were massive , overpriced and unreliable.
Second Generation - (1955-1964)
• The semiconductor replaced vacuum tubes and results in the second generation of computers like UNIVAC a pair of IBM 1401 and government agency 1604.
• These computers were smaller, quicker and additional reliable compared to 1st generation computers .

Third generation: - (1964-1970)
• In early 1960, solid-state electronic technology has been introduced .
• the event of integrated circuits ( ICs).
• On Deck technology as solid state .
• generation instrumentality is additional reliable , quicker and smaller than the previous once .
Forth Generation - (1964 -Present )
• In 1971 , the event of microcircuit technology was sufficient to include all the main functions of a pc on one chip known as " microchip " .
• The introduction of the microchip is that the next generation pc age .
• an immediate consequence is that the development of a microchip or personal computer that brought down the organization in person.
Fifth Generation - (now - beyond)
• process the fifth generation of computers could be a bit tough as a result of the sector is in its infancy .
• the foremost celebrated example of a fifth generation pc is that the fictional HAL900 of the novel by Arthur C. Clarke, 2001 : an area Odyssey .
• The invention of computing of the fifth generation.
• the instance of the fifth generation pc is Pentium four twin core laptop computer supercomputers , personal computers, hand-held computers , mainframes and additional.
• Today, computers have attributes of fifth generation computers . the simplest example could be a.i reborts .
