Did you know that computers are occurring.

History, but the computer was starting to use modern electronic mechanisms in computers. From about 2483 BC.When a computer like this is a first ENIAC (electronic numerical integrator and calculator) at the University of Penn in Philadelphia, USA tube contains approximately 18,000 vacuum tubes The electronic mechanism. This computer is installed in the room about 20 × 10 square meters and weighs over 30 tons because of the suction pipe. That there is a problem of life.The computer does the mortality rate is very often But nevertheless it is indicated that computers have the ability to create interest in the process.

William around 2491 BC.Lay shock (William Shockley), American scientists conducted a research and artificial parts. Called electronic transistors (transistors) from the semiconductor.vacuum tubes instead of transistors to work with efficiency and reliability, and manufacturing industry can do each other a lot. To reduce production costs.Adoption of electronic valves instead of filters transition early in 2503 BC with a computer using the engine electronic transistors. This is the second generation (second generation) of the computer.The new generation of vacuum tubes used. Computers are beginning to produce the next generation of sales in the market.

About Year 2508.Semiconductor technology community a great success that can be created. Many transistors. To stay on the sheet size mm silicon called นั่นเอง circuits or chips.Because the third version of the computer that the engine electronics based IC and you start the computer smaller and the cost of production is reduced.

L '.From computer design flexibility. Both performance and price from now until then. Computer is called a category of large (main frame).Capacity to process and store information at a time can be very complex mathematical calculations with high speed. Another type of computer called. Minicomputer (Minicomputers).poor performance of large computer work rate but at a lower cost. Suitable for small businesses and the science downCurrent minicomputer has evolved both as performance and memory capacity. operation speed production of large computers in the early stages.
