The different generations of computer
First Generation (1945–1959)
|Different Generations of Computer|
Computer: It is also the primary technology related to the first generation of computing machines the first operational electronic general-purpose computer, named the ENIAC (Electronic Numerical Integrator and Computer), was built in 1943 and used 18,000 vacuum tubes.
Using 1,500 vacuum tubes, the machine, like the ENIAC, was programmed using plugboard wiring.
About thirty scientists from both sides of the attended these discussions and several stored programmed machines were soon built.
Von Neumann helped design the IAS (Institute for Advanced Study) machine that was built at Princeton University in 1952. These machines, while still using vacuum tubes, were all built so that their programs could be stored internally another important stored program machine of this generation was the UNIVAC (UNIVersal Automatic Computer). It was the first successful commercially available machine also, during this period, the first IBM computer was shipped. It was called the IBM 701 and nineteen of these machines were sold.
Computer Second Generation (1960–1964)
|Generation of Computer 1st to 5th|
As commercial interest in computer technology intensified during the late 1950s and 1960s, the second generation of computer technology was introduced—based not on vacuum tubes but on transistors IBM soon followed with the transistor-based IBM 7090
Third Generation (1964–1970)
The third generation of computer technology was based on integrated circuit technology and extended from approximately 1964 to 1970
the integrated circuit is a single device that contains many transistors.
Arguably the most important machine built during this period was the IBM System/360. Some say that this machine single-handedly introduced the third generation. It was not simply a new computer but a new approach to computer design. It introduced a single computer architecture over a range or family of devices.
This computer was about 263 times as fast as the ENIAC. During the third generation of computers, the central processor was constructed by using many integrated circuits.
Fourth Generation (1970–?)
The fourth generation of computer technology is based on the microprocessor. Microprocessors employ Large Scale Integration (LSI) and Very Large Scale Integration (VLSI) techniques to pack thousands or millions of transistors on a single chip.
The Intel 4004 was the first processor to be built on a single silicon chip. It contained 2,300 transistors.In 1981 IBM selected the Intel Corporation as the builder of the microprocessor (the Intel 8086) for its new machine, the IBM-PC. This new computer was able to execute 240,000 additions per second. Although much slower than the computers in the IBM 360 family, this computer costs only $4,000 in today’s dollars! This price/performance ratio caused a boom in the personal computer market the machine cost only $4,400 in inflation-adjusted dollars Microprocessor technology is now found in all modern computers.Processor chips are used as central processors and memory chips are used for dynamic random access memory (RAM).
The Intel Pentium Pro PC was a cached, superscalar, pipelined microprocessor
The early developments in computer technology were based on revolutionary advances in technology.
The 5th generation of Computer 1990-presentThe 5th generation began from 1990 to the present, with artificial intelligence. L is also called roboticsGeneration of the computer has been designed to extend the use of artificial intelligence, natural language, expert system and the use of online social networks.The mechanism of work was considered to require the need for human intelligence for the al-capability of the machine. Expert translation system and robotics in interactive game gaming language expert system – An expert system is a computer program that promotes the decisions and behavior of a human or organization, which has expert knowledge and experience in a particular field.
There are four basic types of computers
