What are the characteristics of information? Please give examples of these characteristics.

(1) Dependence. Material is a concrete, real resource; information is an abstract, intangible resource. Information must be attached to a material carrier, and only carriers with a certain amount of energy can be transmitted. Information cannot exist independently of matter and energy. News information cannot be reflected without the facts of a certain time and space, as well as language and newspaper layout.

(2) Regenerative (expandability). Material and energy resources will decrease as long as they are used; while information is constantly expanding and regenerating during use, and will never be exhausted. Today's world is characterized by "energy crisis" and "water crisis" on the one hand, and "information explosion" on the other.

(3) Deliverability. Without transmission, there is no information. There are many ways to transmit information, such as spoken language, body language, handwritten text, printed text, electronic signals, etc.

(4) Storageability. Information can be stored for later use or by others. There are various means of storing information, such as human brain, computer memory, writing, printing, microfilming, video recording, photography, recording, etc.

Extended information

People can understand and transform the world by obtaining and identifying different information from nature and society to distinguish between different things. In all communication and control systems, information is a form of universal connection. In 1948, mathematician Shannon pointed out in a paper entitled "Mathematical Theory of Communication": "Information is something used to eliminate random uncertainty." The most basic unit that creates everything in the universe is information.

Shannon, the founder of information, believed that "information is something used to eliminate random uncertainty." This definition is regarded as a classic definition and quoted.

Norbert Wiener, the founder of cybernetics, believes that “information is the content 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 classic definition.

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