2. Information technology: the scientificity of the method, the advancement of tools and equipment, the proficiency of skills, the richness of experience, the quickness of the process, the efficiency of the function, etc.

Answer]: The generation process of C payment code belongs to information encoding, and item A is wrong. The information itself is not an entity, but only the content contained in messages, intelligence, instructions, data, and signals, which must be transmitted through a medium.

Books and texts are both information carriers, and item B is incorrect. The biggest difference between information and material and energy is that it is shared, and item C is correct. At present, there is no specific and accepted definition of information and information technology, and different people and different fields have different interpretations of it.

However, no matter which way it is expressed, it is a recognized fact that there was information technology in ancient times, and there were still processes such as the collection, processing, storage, and exchange of information in ancient times, and certain technical methods were used in these processes. The advent of electronic computers has only promoted computer technology to become the core and pillar of modern information technology.

Answer]: C Answer] C. Analysis:

Information technology is the application of data and information, which includes: data information collection, representation, processing, security, transmission, exchange, display, management, organization, storage, retrieval, etc. Therefore, C.

Biochemical information based on the acquisition of technology.

Information acquisition technology refers to the technology that can measure, store, perceive and collect various information, especially the technology that directly obtains the important information. Information measurement includes the measurement of electrical signal information and non-electrical signal information. For example, in the automatic control system of industrial production, in order to implement automatic control of various electrical equipment, it is necessary to first measure the parameters such as voltage and current of electrical equipment in order to implement accurate and reliable control.

Voltage and current parameters are a kind of electrical signal information. For some meteorological and hydrological departments, if they want to grasp the changing trend of weather and water conditions and make timely forecasts, they must accurately measure parameters such as air pressure, temperature, wind speed, water depth, and flow velocity, which are all non-signal information. In order to improve the accuracy of information measurement, electronic technology is widely used.

Applications such as electronic anemometers, electronic flow meters and electronic thermometers have become quite common. The electrical signal information can be directly converted into the corresponding information through the circuit, and the non-electric information can be converted into the form of an electrical signal by a converter before it can be input to the electronic circuit for corresponding conversion.

The following belong to the category of "letter fissure number clearing technique" that should be used in the following categories: () aBike sharing.

b.Online courses.

c.Industrial robots.

d.Automatic translation.

Correct answer: ABCD

Information knowledge refers to all information-related chain ruler theories and techniques. This statement is true.

Information knowledge: Information knowledge refers to the theories, knowledge and methods related to information, including information theory knowledge and information technology knowledge. Information theory includes the basic concepts of information, the methods and principles of information processing, and the social and cultural characteristics of information.

With the knowledge of the information itself, it is possible to better distinguish the information from the dust, obtain and use the information. Information knowledge is the foundation of information literacy education.

The content of information knowledge:

1. Traditional cultural literacy. Traditional cultural literacy includes the ability to read, write, and count.

Although the way of reading, writing and arithmetic has undergone tremendous changes and has been given new meanings after entering the information age, the traditional ability of reading, writing and arithmetic is still the foundation of people's cultural literacy. Information literacy is an extension and expansion of traditional cultural literacy.

In the information age, it is necessary to have the ability to read quickly, so that you can effectively obtain valuable information from a wide variety of thousands of information.

2 Basic knowledge of information. It includes the theoretical knowledge of information, the knowledge and understanding of information, the nature of information, the information society and its impact on human beings, and the methods and principles of information (such as information analysis and synthesis method, system overall optimization method, etc.).

3. Knowledge of modern information technology. It includes the principles of information technology (such as computer principles, network principles, etc.), the role of information technology, the development of information technology and its future, etc.

4 Foreign languages. The information society is global, with more than 80 per cent of information on the Internet in English, in addition to other Chinese languages. In order to communicate with each other, it is necessary to understand foreign information and express our ideas, which requires each of us to master 1-2 foreign languages to meet the needs of international cultural exchanges.

The application of information technology includes computer hardware and software, network and communication technology, application software development tools, etc. Since the popularization of computers and the Internet, people have become more and more widely using computers to produce, process, exchange and disseminate various forms of information (such as books, business documents, newspapers, records, movies, television programs, voice, graphics, images, etc.).

In enterprises, schools and other organizations, information technology architecture is a comprehensive structure for the adoption and development of information technology in order to achieve the strategic objectives of the Cautious Late Spring. It includes management and technology components, including mission, functions and information requirements, system configuration and information processes; The technical component includes information technology standards, rules, etc., used to implement the management structure.

The Internet of Things is the combination of technology and computer Internet technology, so that information can be collected, transmitted, processed and executed faster and more accurately, which is the latest form and application of science and technology.

1. Communication satellites.

Communications Satellite: An artificial Earth satellite used as a relay station for radio communications. Space component of the satellite communication system.

Communication satellite ** radio signals, to achieve communication between satellite communication earth stations (including mobile phone terminals) or between earth stations and spacecraft.

2. Photography.

Photography includes optical imaging devices, photosensitive materials, and imaging processes. Light from an object is projected onto a photosensitive material to form a latent image, which is then chemically or physically transformed into a visible image. Here are some of the branches of optical imaging and photography that have been formed in its development.

3. Laser technology.

The laser has the characteristics of good monochromaticity, strong directionality and high brightness. Thousands of laser working substances have been discovered, with wavelengths ranging from soft X-rays to far infrared. The core of laser technology is lasers, and there are many types of lasers, which can be classified according to different methods such as working substance, excitation mode, operation mode, and working wavelength.

Information technology refers to the technology of obtaining, transmitting, storing, processing, displaying and distributing information using electronic computers and modern means of communication
