Explanation of terms What is information technology

Honghan Jinxin "Jin Ji" Han Li Leopard.

Information technology (IT) is a general term for various technologies used 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.

Information refers to the objects transmitted and processed by audio, message, and communication systems, and generally refers to all the content disseminated by human society.

Human beings are able to understand and transform the world by obtaining and recognizing different information about the natural world and society to distinguish different things. In all communication and control systems, information is a form of universal connection. In 1948, the mathematician Shannon pointed out in the ** entitled "The Mathematical Theory of Communication":

Information is something that is used to eliminate random indeterminacy". The most basic unit that creates everything in the universe is information.

Definitions of Terms

The word "information" is "information" in English, French, German, and Spanish, and "intelligence" in Japanese. It first appeared in Hartley's 1928 essay "Information Transmission". In the 40s of the 20th century, Shannon, the founder of information, gave a clear definition of information, and since then many researchers have given different definitions from their respective fields of study.

The representative expressions are as follows:

Shannon, the founder of information, believes that "information is something that is used to eliminate random uncertainty", and this definition is regarded as a classic definition and is cited.

Norbert Wiener, the founder of cybernetics, believed that "information is the internal travel and name that people exchange with the external world in the process of adapting to the external world and making this adaptation react on the external world", which is also cited as a classical definition.

Economic management scholars believe that "information is effective data for providing decision-making".

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

Information technology is mainly the application of computer science and communication technology to design, develop, install and implement information systems and application software. It is also often referred to as Serino information and communication technology, and mainly includes sensing technology, computer and intelligence technology, communication technology and control technology. A general term for methods and equipment used to obtain, process, store, transform, display and transmit text, numerical values, images and sound information, including the provision of equipment and the provision of information services, supported by computer and communications technology.

Application of Information Technology:

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 and periodicals, records, movies, television programs, voices, graphics, images, etc.). <
