Computer history， field and the future developmentA， computer history profileUsed by humans computational tool is with the development of production and social progress， from simple to complex， from low to high， the development process of calculating tool successively appeared like abacus， slide rule， computer， electric machinery brain-scanningexperiments mechanical computer， In 1946， the world's first digital electronic computer (ENIAC) was born in the United S This computer to share more than 18，000 composed， cover an area of electricity in tube 170m2 total weight， 30t， consumed for 140kw， speed 5000 cycles per second to add， 300 times the Electronic computers in a short period of more than 50 years after the electron tubes， transistors， integrated circuit (IC) and large scale integration (VLSI) four stages of development， make the computer volume more and more small， function is more and more strong， the price is lower， used more widely and is currently facing intelligent (the fifth generation computer The first generation of the electronic computerThe first generation of electricity in computer from 1946 to They have large size， low operation speed and storage capacity is not big， and Use isn't very convenient， in order to solve a problem， the program compiled by the complexity of the This generation of computers is mainly used in scientific computing， only the important department or scientific research departments for The second generation of the electronic computerThe second generation of computers from 1958 to 1965， they all adopt transistors as electronic components， its speed than the first generation of computers speed increased nearly 100 times， volume for a small percentage of the In software began using computer algorithmic This generation of computers is not only used in scientific calculations， also used for data processing and transaction processing and industrial The third generation electronic computerThe third generation of computers from 1965 to This period is the main feature of integrated circuits， small-scale for electronic devices， and appear operation system， the computer's function is more and more strong， application more They are not only used in scientific computing， and for the word processing， enterprise management， automatic control and other fields， appeared computer technology and communication technology， combining information management system， can be used in the production management， traffic management， information retrieval， The fourth generation electronic computerThe fourth generation of computers is to show from 1970 after using (LSI) and large scale integration (VLSI) as main electronic components made of For example 80386 microprocessors microprocessors， in an area of about 10mm X l0mm single chip can be integrated about 32 million The fourth generation of computers is another important branch of large-scale， vlsi developed based microprocessor and The fifth generation computerThe fifth generation computer will put information acquisition， storage， manipulation， communication and artificial intelligence together has form reasoning， lenovo， learning and explain Its system structure will break through the traditional von debbi according to the concept of Raman machine， realize the height of parallel Second， computer development directionThe next computer will with very large scale integrated circuit as the foundation， to giant change， miniaturization， network and intelligent Giant of Giant change refers to computer operation speed higher， storage capacity greater， function At present are developing giant computer its speed can reach per 10 billion Nano-scale Micro computer has entered the instrument and meter， household appliances such as small instruments， also as industrial control process of heart， make the equipment to realize "intelligent" With the further development of microelectronics technology， notebook type， such as palmtop microcomputer will end in more optimal price-performance get the welcome of Network Along with the computer application deeply， especially the home computer is becoming more and more popular， on the one hand， hope many users can share information resources， on the other hand also hope all between computers can mutual information The computer network is modern communication technology and computer Computer network yourself in the modern enterprise management plays more and more important role， such as bank system and commercial systems， transportation system， Intelligent Computer artificial intelligence research is based on modern scientific Artificial intelligence is an important direction of computer development， the new generation computer， will can simulate the sensation of behavior and thinking process， mechanism of "see"， "hear"， "says"， "think"， "do"， with logical reasoning， learning， and proof 选为最佳答案吧 谢谢
