What are the characteristics of information?

Information has many basic characteristics, such as universality, objectivity, dependence, enjoyment, timeliness and transitivity. The following is to further understand and recognize the concept of information through the description and discussion of some main features of information.

Universality and objectivity

In nature and human society, things are constantly developing and changing. The information expressed by things is also ubiquitous all the time. Therefore, information is everywhere. Because the development and change of things are independent of people's subjective consciousness, information also exists objectively.

Information is not a concrete thing, nor a substance, but an attribute of objective things. Information must be attached to an objective thing (medium) and exist. The same information can be expressed through different information media, such as words, graphics, images, sounds, movies, animations and so on.

* * * Enjoy

Intangible information is different from material and energy. Matter and energy will be consumed and transformed after use, as shown in figure 1- 1-4.

Information is also a kind of resource, which is of use value. The wider the information is disseminated, the more people use it, and the greater its value and function. In the process of copying, transmitting and sharing information, copies can be generated repeatedly. However, the information itself will not be reduced or consumed.

in time

With the development and change of things, the available value of information will also change. Over time, information may lose its use value, which may be invalid information. This requires people to obtain and use information in time, thus reflecting the value of information.

-Transitivity

Information can be transmitted through the media, which can realize the spatial transmission of information. For example, the live broadcast of the rendezvous and docking of China manned spacecraft Shenzhou-9 and Tiangong-1. Introduce the development of China's space industry to the people of the whole country and even the world. Shorten the distance between the docking site and the TV audience and realize the transmission of information in space.

Information can be transmitted in time through the preservation of storage media. For example, if you can't see the rendezvous and docking live broadcast of Shenzhou-9 and Tiangong-1, you can watch it through playback or replay. This is to use the firmness of the information storage medium to realize the timely transmission of information.

Extended data

Information refers to the objects transmitted and processed through audio, news and communication systems, and generally refers to all the contents spread by human society. People can distinguish different things by obtaining and identifying different information from nature and society, so as to understand and transform the world. In all communication and control systems, information is a common form of communication. 1948, the mathematician Shannon pointed out in his paper entitled Mathematical Theory of Communication that "information is used to eliminate random uncertainty".

Information in a narrow sense is the order in which symbols are arranged. But as a concept, the definition of information presents a situation of multiple definitions and no definition. Generally speaking, concepts closely related to information concepts include constraints, communication, control, data, form, instruction, knowledge, meaning, mental stimulation, mode, perception and expression. Information is the content and name that people exchange with the outside world in the process of adapting to the outside world and making this adaptation react to the outside world.
