Computer artificial intelligence research is based on modern scientific basis. Artificial intelligence is an important direction of computer development, a new generation of computers, will can simulate the sensation of behavior and thought processes, the mechanism "see", "listen", "said," "think", "do", have logical reasoning, learning and proof ability.
Meaning：
Computer science and technology combining of each subject, improved the research tools and methods, to promote the development of the discipline. In the past, people mainly through experiment and theoretical two ways for science and technology research. Now, calculation and simulation has become the third approach research work. The computer and the relevant experimental observations can be combined, instrument field experimental data record, sorting, processing, analysis and draw a diagram, significantly improve the quality and efficiency of experimental work. Computer aided design has become the engineering design of the important means combination, automation. In the aspect of theory, the human brain computer is outspread, can replace the human brain function and strengthened the number. Ancient mathematical rely on paper and pen computing, now computer became the new tools, such as math theorem proving the heavy mental work already may, by computer to complete or partial completed. Calculation and simulation, as a new research method, often makes some disciplines derive new branch discipline. For example, air dynamics, meteorology, elastic structural mechanics and application analysis etc faced by the "dyscalculia", in a high-speed computer and relevant calculation method, and a breakthrough started after derive calculation aerodynamics, meteorological numerical prediction edge branch discipline. Use computer quantitative research, not only in natural science plays a significant role in the social science and humanities subjects also is such. For example, in the census, social investigation and natural language research aspects, computer is a very effective tool. Computer wide application in all walks of life, often produce remarkable economic and social benefits, which led to the industrial structure, product structure, management and service pattern, etc of the revolution. In the industrial structure in the computer industry has a view, and knowledge and computer services industries new industry. Computer application, have computer hardware technical ability, software technology ability, 8 bits embedded microcontroller, 32-bit computer system application ability and good engineering technical ability compound talents. Main course: C series language program design, foundation of computer network, circuit and electronic technology and single-chip microcomputer principle and application, the sensor technology, control engineering foundation, visual programming technology, Linux operating system, interface technology, etc. After graduating in industry measurement device manufacturing enterprise, the civil electronic manufacture of various types of enterprises are engaged in the embedded system software and hardware development work, also can be engaged in industry measurement and control device, the civil all kinds of intelligent electrical repairs. The computer or people learning tools and life tools. With home computer, personal computer, computer network, database systems and all kinds of terminal equipment, people can learn all kinds of classes, get all sorts of intelligence and knowledge, processing various kinds of life issues (such as booking tickets, shopping, different etc), can even home office. More and more people work, study and life with computer will occur directly or indirectly touch. Popularization of computer education has become an important problem. In short, the development of the computer and application has is not only a scientific technology phenomenon and is a kind of politics, economy, military and social phenomenon.
Developing problems：
Our computer application and low level of enterprise informatization level is low, Internet enterprises and Internet families still less, information technology application in enterprise and family enough for popularity. With the developed countries and developing countries have very big gap, according to the state statistical center research, our infomationization ability not only lagging far behind Japan and other developed countries, also behind Singapore, South Korea, the Philippines, Egypt, India and other developing countries; Netizens percentage of the population of 67%, Switzerland, Sweden, Germany, China 60% to 49% only 3.5%. Domestic computer application development is not balanced, regions informatization index 20 times vary, Internet users and computer size in the eastern and western regions, the Chinese mainland and Taiwan region difference, Taiwan Internet users have 5.4 million, the netizen percentage of the population of 26%, networking host 85 million, the enterprise has a 50% yourself in developing electronic commerce, the mainland in developing electronic commerce enterprise less than 10%. China's information industry is not completely satisfy informatization development and computer application on the hardware and software product demand, product technical level and localized market penetration, major application engineering and large application system USES software and hardware product mainly rely on foreign companies, transformation of scientific and technological achievements slow, system integration, information service level should be further enhanced, computer application related standards, norms, and neither need to be unified. Computer application, information of the market economy and policy legal environment remains to be perfect, there is lack of effective technology economics policies promote information technology is widely applied, the information organization, leadership and management system is yet to be perfected and strengthen the market management, the relevant laws and regulations, social credit system has not been fully set up, electronic commerce development need market environment still is not perfected. Enterprise management system, mechanism, management concept and organization of still can not adapt to the requirements of market economy, game lack of knowledge, some leadership to information technology application to the importance and urgency of inadequate understanding. Enterprise using information technology, high and new technology is still lack of internal drive, human, financial and material resources. Basic work is weak, information technology talents especially know both of information technology and understand industry business technology compound talents more lack, broad worker information consciousness and information technology application knowledge lack, worker presses for improving cultural quality.
Development prospects：
During the "ten five", Beijing, Shanghai, guangdong pilot experience will further promote informatization in the scientific concept of development, will be built, led by some informatization demonstration provinces, cities, and areas, urban communities and villages and towns, the 2010 national regions, small and medium-sized city information will be rapid development. Social utility, public service and other public domain informationization been accelerated. Cultural and educational health, social insurance, social security, public transport, water heating power supply system, community service and other public domain will widely applied information technology, key application engineering and gold-lettered series digital Olympic victory completion, public domain informationization level will have a new stage, feed, clothe and shelter for the people provide good environment and service information technology in the home, and promote the development of family information. Intelligent building, the village promotes gradually, the telephone, mobile phone, information home appliances, home computer further popularization, make information technology entered the family and personal life, promoted the development of family information. The national home computer penetration rate in 2005 will reach 8-10%, urban families of 20-30% computer penetration rate by 2010, the national family computer penetration rate will reach 15-20%, urban family computer penetration rate, 40-50 percent information appliances digital, intelligent, home theater, home office will gradually popularizing, family the development of informationization will greatly improve the quality of life.
