What does modern information technology mean?
What is modern information technology?
This paper analyzes the positive effects of modern information technology on urban development, such as urban planning, urban industrial structure, urban spatial layout structure, urban functions, urban transportation, urban architecture, urban management and lifestyle of urban residents, and also analyzes some negative effects of modern information technology on urban development.
The great progress of technology will often bring great influence to the development of cities. The invention of the steam engine led to the initial industrial revolution and urbanization development; The popularity of automobiles has led to the suburbanization of cities. Modern information technology represented by computer and its network technology and modern communication technology is the leading field of contemporary scientific and technological development. Modern information technology is developing at a speed unprecedented by any other technology, involving all aspects of society with a depth and breadth unprecedented by any other technology. "No matter how short the memorabilia in the 20th century, especially since World War II, we will never ignore the great progress of information technology and its extensive economic and social impact." So, what impact does modern information technology have on the development of cities?
First, the positive impact of modern information technology on urban development
Nowadays, the world is marching towards the information age, and information has become the "blood" and "lubricant" of social and economic development. Modern information technology has widely infiltrated and changed people's life, study and work; The information industry is gradually becoming the largest industry in the world. Under the impact of this information wave sweeping the world, many aspects of urban development, such as urban planning, urban construction, urban management, and traditional forms and functions of cities, are also strongly influenced by modern information technology, and cities are facing new development opportunities.
1 improves the efficiency and scientificity of urban planning. Urban planning is the fundamental basis of urban construction, an important means to guide urban construction and implement urban management, and plays a leading role in urban development. Modern information technology expands the theory and practice of urban planning, updates the methods and means of urban planning, greatly improves the labor productivity of planners and the scientificity, artistry and creativity of planning and design schemes, and also strengthens public participation. Future urban planning should fully consider that the "smart city" to be formed in the information civilization era is different from the reorganization of urban spatial structure in any previous era; It is necessary to take geo-information science, human settlement environment science and regional sustainable development as the theoretical and methodological basis, and embody the idea of urban planning: 1 ideal, rationality, comprehensive whole, system, dynamics and ecology; 2. Pay attention to the multi-level human settlement environment with the region as the main body; 3 methods of decision support.
Great changes have taken place in the industrial structure of this city. This is mainly reflected in three aspects: 1 a large number of emerging industries have been produced on the basis of modern information technology; 2. Modern information technology has transformed traditional industries, which has obvious traces of informationization, thus obtaining a new way out; The vigorous development of service industry shows the trend of replacing manufacturing industry in national economy. In short, the urban industrial structure began to change from the traditional industrial economic model to the emerging information economic model. In addition, corresponding to the transformation of urban industrial structure, urban employment presents the characteristics of "softening", that is to say, the proportion of people engaged in "soft occupations" such as management, research, technology development, consulting services and education has increased.
3. The urban spatial layout structure has changed from agglomeration to both agglomeration and dispersion. /kloc-the industrial revolution that broke out in the 0/8th century concentrated capital and population in cities, and started the process of modern urbanization. The development of cities is mainly manifested in the centralized trend based on economies of scale and manufacturing agglomeration and conditioned by the progress of transportation technology. However, with the development of modern information technology, information network will break the time and space restrictions of urban residents' work, education, life, shopping, medical care and entertainment, and people's dependence on offices, schools, shopping centers, hospitals and transportation will be greatly weakened. The dependence of some industrial production on resources and the highly concentrated production scale have also decreased, weakening the motivation of agglomeration. This greatly broadens the activity space of the city, extends the geographical distribution of various functions of the city, and the spatial layout structure of the city also shows a trend of diffusion. Under the general trend of diffusion, cities also have a certain degree of agglomeration. As modern society becomes more and more complex, it needs higher quality coordination and cooperation. & gt

How does modern information technology develop?
With the rapid development of information technology, it has more and more influence on people's life, international military politics and economy. Information technology is developing in a newer direction, with more humanized operation, more personalized products and further improved cost performance, which makes the influence of information technology in all aspects more in-depth and extensive. Keywords: modern information technology; Modern life; As we all know, information technology provides a powerful tool for people's production and life, which can complete the process of data collection, processing and processing, and effectively meet people's various needs for information. For mankind, five information revolutions have created the brilliance of information technology today. With its strong vitality and vigor, information technology has been shining continuously in human history, and even has become one of the technologies most closely related to human life. Whether it is its development status or future trend, it is worthy of our serious face and in-depth study. Judging from the development of information technology in recent years, e-books are not difficult to find. Countries around the world have long planned information technology as a national key strategic development direction, scrambling to invest more manpower and financial resources. Therefore, the rapid development of information technology has covered almost every corner of the world, which has far-reaching significance for human survival and social development. With the support of information technology, our life and national development have undergone earth-shaking changes. First of all, in social life, modern information technology, as one of the modes of information dissemination, with its advantages of high speed, mass and convenience, has quickly occupied the whole world and gradually replaced many traditional ways of information exchange, and even strongly impacted the achievements of the previous four information revolutions: the popularity of online reading materials and e-books has impacted the traditional printing industry; The frequent use of network social software and e-mail affects the use of telegraph and telephone; The popularity and development of online media has also reduced the proportion of radio and television, as shown in figure 1. Secondly, in international military politics, with the gradual maturity and success of information technology, the social pattern that people have developed for many years has been rapidly changed, and even with the attention and investment of various countries in information technology, its application scope has become wider and wider. Military powers constantly increase investment, strive to develop modern military, regard information technology as an important military force, and constantly compete for the commanding heights of information, which indicates that information technology has gradually become the mainstream in many fields such as politics and military affairs. Finally, in the economic aspect, whether it is related industries driven by information technology or enterprises that rely on big data to adjust their development direction, it indicates that information technology has become an inseparable part of the modern economy, and it is constantly changing every field of the world. The future development trend of information technology Information technology is closely related to our life, and every small step of information technology development can reflect the changes of society. Not only in our daily life, information technology in education-related fields will continue to flourish in the future. 2. 1 humanized operation of information technology. More and more friendly man-machine interface is the most obvious development trend of information technology. Because the subject of information technology is people, and its service object is also people, then the state of information technology presented in front of us must also untie the shackles of "machines", and it should be more and more humanized from page presentation to usage, in line with people's usage habits. Take bar code scanner as an example, it has become one of the top ten interface devices between man and machine in the 20th century. A few years ago, barcode scanner only appeared in shopping malls and other occasions, but with the development of information technology, many mobile phone apps now have the function of barcode scanning. However, because its technology has just started, there is still a lot of room for accuracy and operability in simple mobile phone applications. I believe that in the near future, more convenient and practical bar code scanning technology will be popularized, and the development of information technology will go deep into every corner of life, serving mankind more accurately, conveniently and humanely. Personalized development of mobile phone 2.2 information technology products. With the expansion and complexity of information technology users, personalized functional design is also an inevitable trend of information technology development in the future. With the rapid change of social and economic environment, people choose more and more information technology, and the competition in the information industry is becoming more and more fierce, which requires the developers of the information industry to develop different information products according to different use needs, and meet people with increasingly complex needs with constantly updated technologies.

What is the basis of modern information technology?
Information technology refers to the technology of information collection, identification, extraction, conversion, storage, transmission, processing, retrieval, detection, analysis and utilization. All departments involved in these processes and technologies can be called information departments. Information technology can extend or expand people's information function. Information technology may be mechanical or laser; It may be electronic or biological. Information technology mainly includes sensing technology, communication technology, computer technology and microform technology. The task of sensing technology is to extend the information collection function of human sensory organs; The task of communication technology is to expand the function of human nervous system to transmit information; Computer technology extends the function of human thinking organs to process information and make decisions, while microfilm technology extends the function of human memory organs to store information. Of course, this division is only relative and general, and there is no clear boundary. For example, there are also information processing and collection in the sensing system, while there are both information transmission and information collection problems in the computer system. At present, a large number of sensitive elements have been developed in sensing technology. In addition to ordinary cameras can collect visible light wave information, microphones can collect sound wave information, and now there are sensitive components in infrared and ultraviolet bands to help people extract important information that the human eye can't see. There are also ultrasonic and infrasound sensors that can help people get information that those people can't hear. Not only that, people have also made various olfactory, gustatory, light-sensitive, heat-sensitive, magnetic, humidity-sensitive and some comprehensive sensitive elements. In this way, we can also extract useful information that can't be collected by various human sensory organs, thus prolonging and expanding the function of human collecting information. The development speed of communication technology is amazing. From the traditional telephone, telegraph, radio and television to the present mobile phone (mobile phone), fax and satellite communication, these new modern communication means, which are accessible to everyone, greatly improve the efficiency of data and information transmission, so that the work that used to have to be done by professional telecommunications departments can be done directly and conveniently by the staff of administrative and business departments. Communication technology has become the supporting technology of office automation. Computer technology and modern communication technology together constitute the core content of information technology. Computer technology has also made rapid development, with smaller and smaller size and stronger functions. From mainframe, medium-sized computer and minicomputer to microcomputer, notebook computer and portable computer. From PC, 286,386 to 486,586, the application of computers has also made great progress.

What are the applications (examples) of modern information technology and what is its impact?
In our daily life, even going to school, shopping, seeing a doctor and all kinds of entertainment activities, we can also rely on the computer network. You don't have to buy DVDs one by one, just watch them online. We can get the latest news anytime and anywhere without subscribing to the newspaper and turning on the computer, and so on. At that time, computers, televisions, telephones, fax machines, DVD players and audio equipment had been integrated into one machine, which was highly intelligent and became a home robot, which could automatically provide services for us, act as security guards, nannies and secretaries, automatically judge the identity of guests, leave messages for guests and automatically transfer them to their owners. It can help take care of children and the elderly, automatically send disease reports to hospitals, automatically clean rooms, cook meals, and so on. But also can be automatically switched on and off according to the presence or absence of information, thereby saving energy and protecting the environment.
