Question 2: What are the main features of information? ? 10 points are authenticity, timeliness, * * * enjoyment, hierarchy, incompleteness, stagnation and transformation.
Another information test is: carrier dependence; Value; Timeliness; * * * Enjoy.
Question 3: 2. What are the basic characteristics of information? The characteristics of information are determined by the nature of information. Has the following characteristics:
1, Infinite: Information is a way, form or activity state of material existence, and material is in endless activities, which determines the infinity of information. Material and energy are infinite, and information is inexhaustible. Human beings will rely on these three resources for survival and development, and there will be no end.
2. Identifiability: Information can be recognized directly through the senses or indirectly through various wrists. Because the carrier styles of information are diversified, different information can be recognized in different ways;
3. Convertibility: information can be converted from one information carrier to another, such as material information can be converted into language, characters, graphics, symbols, codes, signals, etc. And each information carrier can be transformed into each other, from language to other codes, from graphics to text, etc.
4. Storability: Humans can have brains to store information as "internal language", which is a kind of hidden storage, and they can also store information with machinery and equipment, such as computers, tape recorders and video recorders.
5. Expansibility and compactness: things are constantly moving, information is constantly abandoning the old and letting the new, and the total amount of information in society is constantly increasing and expanding. By summarizing and summarizing the information, the information capacity can be greatly reduced, which is conducive to progress and effectiveness;
6. Substitutability: accurate use of information can improve efficiency and reduce consumption, and information is commensurate with the functions of capital, labor, material and energy;
7. Transitivity: This is one of the essential attributes of information. Under the carrier information, information is transmitted in society, but information is only transmitted, and ability has the function of eliminating uncertainty, that is, the function and function of information are realized through communication ability, so transmissibility is its essential attribute;
8. Shareability: Information can be shared. Except for certain information and certain people, the information transmitted in a certain range can generally be shared by every individual in this category;
9. Combinability: When some information is intentionally or unintentionally combined, it will form new information different from the original information. For example, montage is a combination of information. Montage comes from French montage, which means composition and assembly. It means that "in the creation of film and television works, the shots are connected according to a certain logical relationship, and through the complementary or antagonistic relationship between images, the interaction produces coherence, contrast, echo, association, suspense and other consequences, forming a relatively complete ideographic whole." This shot is a message, and different combinations can have different meanings and consequences. In addition, sound effects can also be combined to produce a similar lens montage. For example, clapping, silence, noisy voice and speaker voice will have different meanings if they are arranged and combined, which can be expressed in a noisy crowd. A person made a wonderful speech, the crowd calmed down, listened carefully, and finally gave warm applause; If it is applause, silence, the speaker's voice and noisy voices, it can mean that people are waiting to listen to the speech, but the speech is boring, people can't help chatting with each other, and the scene is very noisy.
10, Incompleteness: It is impossible and unnecessary for any information to reflect all aspects of the objective object, it is only the reflection and change of one aspect of things.
Question 4: What are the characteristics of information? Information is everywhere.
2. Information is attached to some kind of carrier.
3. Information can be transmitted.
4. Information is time-limited.
5. Information can be processed.
6. Information can be forged.
Question 5: What are the basic characteristics of the information society? The concept of "informatization" was put forward in the early 1960s. It is generally believed that informatization refers to the dynamic development process in which information technology and information industry play a leading role in economic and social development. It is mainly marked by the proportion of information industry in the national economy, the application degree of information technology in traditional industries and the level of information infrastructure construction.
From the content, informatization can be divided into three aspects: information production, application and guarantee. Information production, that is, information industrialization, needs to develop a series of information technologies and industries, involving information and data collection, processing and storage technologies, including communication equipment, computers, software and consumer electronics manufacturing. Information application, that is, informatization in industrial and social fields, is mainly manifested in the transformation and upgrading of traditional industries such as agriculture, manufacturing and service industries by using information technology, which greatly improves the utilization efficiency of various materials and energy resources, promotes the adjustment, transformation and upgrading of industrial structure, and promotes profound changes in human life style, social system and social culture. Information guarantee refers to the infrastructure and security mechanism to ensure information transmission, so that human beings can continuously improve their ability to obtain information, including infrastructure construction, information security guarantee mechanism, information technology innovation system, information dissemination channels and information ability education.
There is no principle difference between the concepts of information society and post-industrial society. Information society, also known as information society, is a society in which information will play a major role after leaving the industrialized society. In agricultural society and industrial society, material and energy are the main resources, engaged in large-scale material production. In the information society, information has become a more important resource than matter and energy. Information economy activities aimed at developing and utilizing information resources have expanded rapidly, gradually replacing industrial production activities and becoming the main content of national economic activities. Information economy occupies a dominant position in the national economy and is the material basis of social informatization. The information technology revolution led by computer, microelectronics and communication technology is the power source of social informatization.
Due to the wide application of information technology in data production, scientific research and education, medical care, enterprise and * * * management, family and other fields, it has had a significant and far-reaching impact on economic and social development and fundamentally changed people's lifestyle, behavior and values.
In 1980s, the popular sayings about "information society" were "3C" society (communication, computerization and automatic control), "3A" society (factory automation, office automation and home automation) and "4A" society (3A plus agricultural automation). In the1990s, the discussion about the information society was accompanied by the widespread adoption of multimedia technology and information superhighway network. Specifically, it has the following three characteristics:
1, the characteristics of the economic field
(1) The labor structure has undergone fundamental changes, and the number of people engaged in the information profession has an absolute advantage over other departments;
(2) In the gross output value of the national economy, the output value created by the information economy has absolute advantages compared with the output value created by other economic sectors;
(3) Less energy consumption and less pollution;
(4) Knowledge has become a huge resource for social development.
2. Social, cultural and life characteristics
(1) Computerization and automation of social life;
(2) It has a long-distance rapid communication network system with wide coverage and various data centers with quick and convenient remote access;
(3) Diversification and individualization of life patterns and cultural patterns;
(4) The time and activity space available to individuals are greatly increased.
3. Characteristics of social concepts
(1) It has become a social trend to respect the values of knowledge;
(2) People in society tend to create the future more actively.
Question 6: What are the main features of informatization? 1. Characteristics and definition of informatization. Informatization refers to the process that information and knowledge are the main resources, supported by computers and mathematics, and information processing is the main mode of production. Viewpoint 1: Informatization is a process, which refers to the process of improving the productivity of knowledge and information with the improvement of people's education level, and its essence is knowledge. Viewpoint 2: Informatization is the extensive application of information technology in politics, economy, culture and social life. Viewpoint 3: Informatization refers to the transformation process of economic development from material and energy to information and knowledge. Viewpoint 4: Informatization refers to the process that the departments engaged in information processing and their information activities (including information production, transmission, exchange and utilization) play a relatively greater role in the national economy and eventually surpass agriculture, industry and service industries. Viewpoint 5: Informatization refers to the dynamic process in which the information industry is highly developed and occupies a dominant position in the national economy, which embodies the fundamental transformation from material products to information products. Viewpoint 6: Informatization is the use of modern information technology to realize the full enjoyment of information resources and solve various problems in social and economic development. Connotation and characteristics of informatization: "four modernizations" and "four natures" 1. Intelligent 1. Comprehensiveness II. Electronic II. Competitiveness 3. Globalization. Permeability 4. Non-grouping 4. Openness II. The concept of digital divide. "In all countries, there are always some people who have the best information technology provided by society. They have the most powerful computers, the best telephone service, the fastest network service and the best education. In addition, some people can't use the latest or best computer, the most reliable telephone service or the fastest and most convenient network service for various reasons. The difference between these two types of people is the so-called' digital divide'. " Due to the uneven distribution of information technology resources and unequal application of information technology, the situation of "having" and "not having" information technology resources among countries, nationalities and even individuals is gradually increasing. The digital divide is caused by geographical differences, ethnic groups, economic conditions, gender and differences in technology, knowledge and ability to use information technology resources such as the Internet. 3. Briefly describe the impact of information technology on society. (A) the impact on the way of thinking, thinking subjects: individuals, human brains-groups, human-computer thinking objects: the real world-virtual thinking media: industrial civilization-network technology and information technology (B) the impact on the mode of economic growth Resource input: high consumption and high pollution-natural resources are increasingly exhausted, industrial pollution is aggravated, and environmental degradation is aggravated-information-related industries: biotechnology, electronic technology. (4) Impact on lifestyle 1. Ideas are greatly exchanged, infiltrated and influenced each other. 2. Great changes have taken place in work style. Visiting friends, shopping, meetings, entertainment and other things can be done through the internet.
Question 7: What are the main features of the information society? Information society is synonymous with information society. The information society is the result of "information socialization and social informatization" and the product of "knowledge of natural information, informatization of primitive society, agricultural society, industrial society and knowledge society". The basic nature of social production factors has not changed, but they are not the elements of information. They are all transformed into intellectual information through digitalization, coding, literariness, charting, audio-visual and standardization. Then create an information management system (including information engineering system, information database network system, information service system, information collection, processing, storage, database construction, networking, retrieval, research, compilation, consultation, communication, intelligent system application and other information system creation activities) to implement and strengthen the information management of intellectual information, information resources, information systems and information users, and promote the rapid development and progress of the information society. Therefore, the basic feature of the information society is that "everything becomes intellectual information", and people themselves are also informationized, such as ID card coding and certificate coding.
The factors of production in the information society are inseparable from people, money, goods and management from the information fool's point of view, but they must be transformed into information knowledge (that is, information process). Transform "people, finance, materials and management" into intellectual information (such as digital information, coded information, text information, chart information, audio-visual information, network information, automation information, system information, control information, user information, management information, energy information, material information, product information, economic information, cultural information, medical and health information, scientific research information, experimental information and traffic information). . . . . Therefore, the most basic factors of production are "intellectual information", "information system", "information users" and information management. Otherwise, it is not an information society. My humble opinion, please criticize!
