The network makes the information society evolve to a new stage. From the perspective of historical development, information technology can be divided into three different stages: ancient information technology, modern information technology and modern information technology. From 3000 BC to 1837 AD, it was the ancient information technology stage; From 1837 to the 1960s, the telecommunications revolution was the modern information technology stage; Since the 1960s, it is the stage of modern information technology. Only at the stage of modern information technology can information technology bring about revolutionary changes in all walks of life. The information industry formed on the basis of the industrialization of information technology and the information economy formed on the basis of the informatization of all walks of life occupy an increasing proportion in the national economy, thus showing the characteristics and models of the information society.
Since the 1960s, due to the development of electronics, especially semiconductor technology, microelectronics technology, integrated circuit technology and other fields, major breakthroughs have been made, and computer technology has made great progress, which has led to revolutionary progress in information processing technology. The resulting computer industry is also at the height of its power. The rapid development of processing technology urgently needs the rapid development of transmission technology. Based on the pressure and thrust of technology and market, with the rapid development of network and communication technology, a new stage of the information society is ushered in, that is, the network era. Website construction Drive the development and sorting of information. Development is to get a lot of original information from nature. Sorting out is to draw useful information from the existing information ocean. Since the mid-1990s, countries have increasingly focused on database technology, information mining technology, information standardization technology, sensing technology, side detection technology and other aspects, forming a research boom in information acquisition technology. The ultimate purpose of information technology development is to apply. So information application technology began to spring up. Digital technology, interface technology, integration technology, intelligent technology, etc. will also be rapidly developed, and an intelligent era is about to emerge.
In order to ensure the leading position of the United States in the field of information technology, President Clinton will propose to increase the investment in information technology research by $366 million, or 28%, in his 2000 fiscal budget proposal. This investment in information technology has been substantially increased, aiming at promoting basic research in computer technology and communication technology; Support advanced computer science and engineering research; Support research on the impact of information technology on economy and society, and cultivate more information technology talents. In the United States, 60% of new employment opportunities require workers to have the ability to skillfully use information technology, but only 25% of them meet this condition. Therefore, education must be reformed to create an environment for lifelong learning and constantly updating knowledge for the public. The United States also extended the tax relief policy for high-tech enterprises that will expire. The implementation of this policy is equivalent to an annual increase of 2.4 billion US dollars in government investment in high-tech research. At present, more than one-third of the economic growth in the United States comes from information technology. The rapidly developing information technology industry has created more than 7.4 million jobs for the United States, changing the way people live, work, study and communicate.
