History of Computer

If in the previous post I explained how computing can be done without a computer, so in this post I will tell you about how a computer, which is a new computing engine, can be created in this world. I will first explain how the computer there, to how computers can develop until today. In this post I will explain the five generations of computers in the world.

First Generation

Computer generation zama was created in the second world war. At first the computer is used to assist the military field. In 1941, Konrad Zuse, a German engineer to build a computer, the Z3, to design airplanes and missiles. Another computer development in this generation is the ENIAC. ENIAC is a versatile computer (general purpose computer) that work 1000 times faster than previous computers. Then came the computer which has a Von Neumann architecture models, models with a memory to hold both programs and data. This technique allows the computer to stop at some point and then resume her job back. UNIVAC computer name is I (Universal Automatic Computer I). In this generation, computers only do a certain task and the physical size of the computer in this generation is very large due to a very large component wear anyway.

The second generation

If the previous generation of very large size of the computer, in this emerging generation of human mind to create a computer as efficiently and as small as possible. In this generation created a transistor in 1948. As a result, the size of electric machines is reduced drastically. Another discovery is the development of magnetic-core memory development of second generation computers smaller, faster, more reliable, and more energy efficient than their predecessors. At this age appeared several programming languages ​​such as Common Business-Oriented Language (COBOL) and FORTRAN (Formula Translator). It makes people better understand math formulas and computer code on the machine. This makes it easy for someone to program a computer.

Third Generation

If the previous generation of computers possess a computer transistor sizes that make being dropped drastically, in this generation of humans has a new problem again. Transistor is used to produce heat, causing considerable damage to the components inside the computer. To resolve this problem, a new idea emerged from humans to create new components made of quartz stone. Is developing an integrated circuit (IC: integrated circuit) in 1958. In this generation people also condense computer components into a single chip called a 'semiconductor'. The result size becomes smaller computers. Computer growing in this generation, to develop an operating system. With this operating system, the computer can run multiple programs simultaneously (multiprogramming).

Fourth Generation

In this generation, the only computer is a smaller size and simple. Was created Large Scale Integration (LSI) which can fit hundreds of components on a chip. And smaller in the 1980s, Very Large Scale Integration (VLSI) contains thousands of components in a single chip. Does not stop there, people also grow on a computer chip with creating Ultra-Large Scale Integration (ULSI) which can increase the number of components contained into the millions. It also causes computers become cheaper price because the components used to be smaller and simpler. Computer at this time and began to spread widely known. And began to develop from the PC (personal computer), a computer that could be included in the bag (laptop), until the computer can be hand held (palmtop). Because humans are aware, very lacking in computer graphics problems, comes the graphic system created by Apple Macintosh. It also led to the market being crowded computer graphics. Computers continues to grow, so the idea of ​​creating a human network connections between computers to share and communicate. Be known direct cabling, network LAN (Local Area Network or LAN) or telephone cable.

Fifth Generation

In this generation, computers are getting smarter. Computer development at this time, more to the technological advances in computer intelligence. On this emerging generation artificial intelligence (artificial intelligence or AI). With this computer has a 'brain' to be able to hold conversations with humans, using visual feedback, and learn from his own experiences. Advances in computer technology is also available on the parallel processing capabilities. Computer at this age can coordinate many CPUs to work in unison. Another technology that is superconducting. This allows the flow of electricity without any obstacles and to accelerate the speed of information.
