Is IT information technology? What does that mean?

Information technology is an umbrella term for the various technologies used primarily to manage and process information.

It mainly applies computer science and communication technology to design, develop, install and implement information systems and application software. It is also often referred to as information and communications technology (ICT). It mainly includes sensing technology, computer and intelligent technology, communication technology and control technology.

The main contents of information technology are:

Perception and recognition technology, whose function is to expand the human ability to acquire perception through perception and recognition. Information identification technology includes information identification, information extraction, information detection, etc. This technology is known as "sensing technology".

It is capable of expanding the full range of sensory perceptions of the human body. Information recognition includes text recognition and speech recognition.

image recognition, etc. The main role of information transmission technology is to realize the fast, reliable and secure transmission of information. All communication technologies.

can all fall into this category. Broadcasting technology also has the function of disseminating information.

Any technology that can expand people's information functions is information technology. It can be said that this is the basic definition of information technology. It mainly refers to the use of electronic computers and modern means of communication to achieve information acquisition, transmission, storage, processing, display, distribution of information, etc.

Specifically, information technology mainly includes the following technologies:

1.Sensing and recognition technology, its role is to expand the function of the sensory organs in which people obtain information. It includes technologies such as information identification, information extraction, and information detection.

The general term for this type of technology is "sensing technology".It can expand the sensing function of almost all human sensory organs. The remote sensing technology produced by the combination of sensing technology, measurement technology and communication technology has further strengthened people's ability to perceive information.

Information recognition includes text recognition, speech recognition, and graphic recognition. This is usually done using a method called "pattern recognition".

2.The main function of information transmission technology is to realize the fast, reliable and safe transfer of information. Various communication technologies fall into this category.

Broadcasting technology is also a technology for transmitting information. Since storage and recording can be regarded as an activity of transmitting information from the "present" to the "future" or from the "past" to the "present", it can also be regarded as a kind of information transmission technology.

3.Information processing and regeneration technologyInformation processing includes encoding, compression, and encryption of information. On the basis of the processing of information, some new and deeper decision-making information can also be formed, which is called the "regeneration" of information

The processing and regeneration of information depend on the extraordinary capabilities of modern electronic computers.

4.Information application technology is the final link in the information process. It includes control technology, display technology, etc.

It can be seen from the above that sensing technology, communication technology, computer technology and control technology are the four basic technologies of information technology, among which modern computer technology and communication technology are the two pillars of information technology.

They are the next-generation communication network, the Internet of Things, the integration of three networks, the new flat panel display, the high-performance integrated circuit and the high-end software represented by cloud computing.

The new generation of information technology not only refers to the vertical upgrading of some branch technologies in the information field, such as integrated circuits, computers, wireless communications, etc., but also refers to the intergenerational changes of the overall platform and industry of information technology. The new generation of information technology is one of the seven strategic emerging industries identified, and it is required to increase the support policies of finance, taxation and finance.

Scope of Information Technology Applications: The study of information technology includes science, technology, engineering, and management disciplines, the application of these disciplines in the management, transmission and processing of information, related software and equipment and their interactions. 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 commonly using computers to produce, process, exchange and disseminate various forms of information (such as books, business documents, newspapers, records, movies, television programs, voices, graphics, images, etc.).

1) Broadly speaking, information technology refers to the sum of various methods, tools and skills that can fully utilize and expand the functions of human information organs. This definition emphasizes the philosophical exposition of the essential relationship between information technology and human beings.

2) In the middle sense, the technology refers to the sum of various technologies for collecting, transmitting, storing, processing and expressing information. This definition emphasizes the general understanding of information technology functions and processes.

3) In a narrow sense, information technology refers to the sum of technologies that use various hardware equipment and software tools and scientific methods such as computers, networks, radio and television to obtain, process, store, transmit and use various information on text, image, sound and video. This definition emphasizes the modernization and high-tech content of information technology.
