What are the application fields of information technology?

Information technology is a new field of science and technology that studies the acquisition, transmission, processing, storage, display and widespread use of information. It involves remote control and telemetry technology; Communication and television technology; Computer technology; Optical disk, magnetic disk and semiconductor storage technology; Various display terminals and display screen technologies; Various information service technologies and so on. Information technology will permeate the whole society, economy and all aspects of people's lives. In particular, the completion of the information superhighway and highly developed digital network will connect countries, regions, units and individuals all over the world. It makes the world very small and information is transmitted very quickly, creating excellent objective conditions for human beings to enjoy knowledge and spiritual wealth.

Information technology is changing people's production mode. In the past, the mode of production was to design first, then trial-produce, and then produce and sell. In this process, if the trial production is completed and the products are found to be unqualified during sales, it will take a long time to go back and start again. Using advanced technologies such as computer aided design system and computer integrated manufacturing system, the design, trial production, production and sales departments are linked in the computer network, and virtual technology is used to display on the computer network, so that all research, design, production and sales personnel can participate at the same time, forming a one-time design, production and sales. The cycle of design, processing and circulation is greatly shortened, and the product quality and production efficiency are improved. In addition, business automation technologies such as management information system, enterprise information integration and e-commerce will improve the competitiveness of enterprises.

Information technology is changing people's work and lifestyle. In the information society, families are equipped with computer-integrated transaction processing workstations, which integrate the functions of high-definition digital TV, hi-fi, telephone, camera, fax, e-mail, data transmission and expert system. Through the information superhighway, families are connected with schools, work units, libraries, museums, news databases, TV program libraries, commodities and service units. And interact at high speed to meet various needs in work and life. By then, people can work at home, housewives will be liberated, and intelligent robots will replace some housework to realize online education, online meetings, online hospitals and online shopping. Rich and fully functional intelligent application systems and service software for individuals and families will greatly improve the quality of work and life.

2 1 century, information technology will change social form, economic growth mode, people's lifestyle and way of thinking more and more profoundly, and it will become the most important factor to measure comprehensive national strength. In the 2 1 century, information technology will bear fruitful results.
