Computer history, field and the future development
A, computer history profile
Used 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, etc. In 1946, the world's first digital electronic computer (ENIAC) was born in the United States. 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 multiplication.
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 direction.
1. The first generation of the electronic computer
The first generation of electricity in computer from 1946 to 1958. They have large size, low operation speed and storage capacity is not big, and expensive. Use isn't very convenient, in order to solve a problem, the program compiled by the complexity of the unspeakable. This generation of computers is mainly used in scientific computing, only the important department or scientific research departments for use.
2. The second generation of the electronic computer
The 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 original. In software began using computer algorithmic language. This generation of computers is not only used in scientific calculations, also used for data processing and transaction processing and industrial control.
3. The third generation electronic computer
The third generation of computers from 1965 to 1970. 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 widely. 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, etc.
4. The fourth generation electronic computer
The fourth generation of computers is to show from 1970 after using (LSI) and large scale integration (VLSI) as main electronic components made of computer. For example 80386 microprocessors microprocessors, in an area of about 10mm X l0mm single chip can be integrated about 32 million transistors.
The fourth generation of computers is another important branch of large-scale, vlsi developed based microprocessor and microcomputer.
5. The fifth generation computer
The fifth generation computer will put information acquisition, storage, manipulation, communication and artificial intelligence together has form reasoning, lenovo, learning and explain capabilities. Its system structure will break through the traditional von debbi according to the concept of Raman machine, realize the height of parallel processing.
Second, computer development direction
The next computer will with very large scale integrated circuit as the foundation, to giant change, miniaturization, network and intelligent direction.
Giant of 1.
Giant change refers to computer operation speed higher, storage capacity greater, function stronger. At present are developing giant computer its speed can reach per 10 billion times.
Nano-scale 2.
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 people.
Network 3.
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 communication.
The computer network is modern communication technology and computer techniques. Computer network yourself in the modern enterprise management plays more and more important role, such as bank system and commercial systems, transportation system, etc.
Intelligent 4.
Computer artificial intelligence research is based on modern scientific basis. 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 ability.

History of computer development, and future development areas
I. Introduction to Computer History
Computational tools used by human beings, with the development of production and social progress, from simple to complex, from lower to higher development, computational tools have emerged, such as abacus, slide rule, hand mechanical computers, electrical machinery and computer . In 1946, the world's first electronic digital computer (ENIAC) was born in the United States. This computer has more than 18,000 shared power in the tubes, an area of 170m2, the total weight of 30t, power 140kw, computing speed of the 5000 additions per second, 300 times multiplication.
Computer in just 50 years after the tubes, transistors, integrated circuits (IC) and ultra large scale integration (VLSI) four stages of development, so that the computer smaller and smaller, more powerful, the price getting lower and lower, more and more widely, currently moving intelligence (fifth generation) computer direction.
1. The first generation of computer
The first generation of electricity in the computer is from 1946 to 1958. They are larger, lower operation speed, storage capacity is small and expensive. Not easy to use, in order to solve a problem, the complexity of programmed elusive. This generation is mainly used for scientific computing, scientific research only in the key sectors or departments.
2. Second-generation computer
Second-generation computer is from 1958 to 1965, they all use the transistor as an electronic device, the operation speed than the first generation of faster computers in recent times, the volume of several one-tenth of the original. In terms of software to start using computer algorithms language. This generation not only for scientific computing, but also for data processing and transaction processing and industrial control.
3. Third-generation computer
The third generation of computer is from 1965 to 1970. The main characteristics of this period is, the small-scale integrated circuits for electronic devices, and operating system appears to make more powerful computers, applications and more wide. They not only used for scientific computing, but also for word processing, business management, automatic control and other fields, there has been computer technology and communication technology combines information management system for production management, traffic management, information retrieval and other fields.
