History Of Computer

History Of Computer

It is well known that computers have changed the way of life. The computer has transformed the way we communicate and learn due to business . Restart the computer control have replaced the backup task performed by humans.
The information revolution is to be found infected in every way to his own life . Today all computers in machine control .
Example: -
Train , plane, etc Automobiles

Computer Generation:

First Generation - (1945-1955)
• The computers, ENIAC , EDVAC , UNIVAC and Mark 1 covers the initial phase of development of computers belonging to the first generation of computers.
• This equipment is mainly made ​​"between" 1945-1955 .
• The computers developed in this generation used vacuum tubes.
• devices These devices were faster calculation time . However, the memory size of these computers was limited.
• They were big , expensive and unreliable.

Second Generation - (1955-1964)
• The transistor replaced vacuum tubes and leads to the second generation of computers like UNIVAC 2 IBM 1401 and CDC 1604.
• These computers were smaller, faster and more reliable compared to first generation computers .

Third generation: - (1964-1970)
• In early 1960, solid-state electronic technology has been introduced .
• The development of integrated circuits ( ICs).
• On Deck technology as solid state .
• generation equipment is more reliable , faster and smaller than the previous once .

Forth Generation - (1964 -Present )
• In 1971 , the development of integrated circuit technology was sufficient to incorporate all the major functions of a computer on a single chip called " microprocessor " .
• The introduction of the microprocessor is the next generation computer age .
• A direct consequence is the development of a microprocessor or microcomputer that brought down the organization personally.

Fifth Generation - (now - beyond)
• Defining the fifth generation of computers is a bit difficult because the field is in its infancy .
• The most famous example of a fifth generation computer is the fictional HAL900 of the novel by Arthur C. Clarke, 2001 : A Space Odyssey .
• The invention of Artificial Intelligence of the fifth generation.
• The example of the fifth generation computer is Pentium 4 dual core laptop supercomputers , personal computers, handheld computers , mainframes and more.
• Today, computers have attributes of fifth generation computers . The best example is a.i reborts .
