Types of information technology industry

The information technology industry mainly includes three industry departments: ① Information processing and service industry, which is characterized by using modern computer systems to collect, process, sort out and store information and provide various information services for various industries, such as computer centers, information centers and consulting companies. (2) The information processing equipment industry is characterized by engaging in research and production of electronic computers (including hardware manufacturing of related machines) and computer software development. Computer manufacturing companies and software development companies can be counted as this industry. (3) Information transmission intermediary industry, which is characterized by using modern information transmission intermediary to deliver information to the destination timely, accurately and completely. So printing, publishing, news broadcasting, communication, post and telecommunications, and advertising can all be included. Information industry can be divided into primary information industry and secondary information industry. The former includes traditional goods and services to transmit information and intelligence, while the latter refers to services provided to internal consumers such as governments, enterprises and individuals.

Information technology industry is a new industry. It is based on modern scientific theory and technology and adopts advanced theory and communication technology. It is a high-tech service industry. The development of information industry is of great significance to the development of the whole national economy. The information industry makes the transmission of economic information more timely, accurate and comprehensive through its activities, which is conducive to improving the labor productivity of various industries. The information technology industry accelerates the spread of science and technology and shortens the distance from creation to application in production. The development of information industry promotes the development of technology-intensive industries and is conducive to the adjustment of national economic structure.

It is precisely because of these advantages that information technology has made rapid progress since the emergence of computer technology. Its application has penetrated into all walks of life and every corner of society, greatly improving the level of social productivity and bringing unprecedented convenience and benefits to people's work, study and life.

Although today's information technology has brought unexpected benefits to people, the pace of technological progress will not stop. In the technological transformation facing 2 1 century, the development direction of information technology will be intelligence.

Today's information technology has surpassed the human brain's ability in information processing in some aspects, such as memory ability, computing ability and so on; But it is not as good as human brain in many aspects, such as character recognition, speech recognition, fuzzy judgment, fuzzy reasoning and so on. More importantly, the human brain can continuously improve its information processing ability through self-learning, self-organization and self-adaptation. All the capabilities of the stored program computer are given to it by people through programming. It is mechanical and rigid, and cannot improve itself compared with the human brain.

In view of the above problems, people began to study the theory and technology of intelligence many years ago, and explored the mechanism of human brain information processing in order to better simulate the function of human brain with machines. After decades of efforts, the theory and technology of intelligence have made great progress. It is these advances that provide the foundation for the intelligentization of information technology.
