What are the characteristics of information, and the characteristics of information include:

Information is indestructible. Information is not like objects and energy, matter is indestructible, energy is also indestructible, its form can be transformed, but the indestructibility of information is different from theirs. A cup is broken, and the atoms and molecules of the ceramics that make up the cup have not changed, but they no longer become a cup.

Another example is energy, we can turn electrical energy into heat energy, but after turning it into heat energy, the electrical energy is gone. The indestructibility of information means that after a piece of information is generated, its carrier can be changed and can be destroyed, such as a book or a CD, but the information itself has not been destroyed, so the indestructibility of information is a great feature of information.

Information can be reproduced cheaply and can be widely disseminated. The reproduction of information is not like the reproduction of objects, and the cost of copying a piece of information into 1 million pieces of information is very low. Although the creation of information may require a large investment, replication requires only the cost of the carrier, and can be replicated in large quantities and widely disseminated.

The value of certain information is very time-sensitive. A piece of information is very valuable at one point, but after that point, it may have no value at all. Financial information can be very valuable when it needs to be known, but after that moment, it will be worthless.

Another example is information in wartime, the information of the enemy has a very important value at a certain moment, which can determine the victory or defeat of a war or campaign, but after this moment, this information becomes useless. Therefore, a considerable part of the information is very time-sensitive.

The definition of information is very broad, all walks of life are inseparable from information, and now it is the information age, whether it is work, study or life, information is everywhere, and information has the characteristics of generality, sensitivity, dissemination, and openness.

Dependency. Value. Timeliness. Shareability. Authenticity. Processability. Processability.

Dependency: The information must be attached to a certain ** medium to manifest, such as: when you see the ants moving, you can know that it is going to rain soon.

Value: Information can meet people's needs in some aspects, such as: information will be valuable to students in the first year of high school. For example, there are 1,000 Hamlets for every 1,000 readers.

Timeliness: Information will change with the change of objective things, such as: weather forecast, market information will change over time.

Authenticity: "Ming Xiu Plank Road, Secret Crossing Chen Cang", Zhuge Liang's "Empty City Plan".

Processability: jade is not cut, not into a device. Meng Haoran's poems are straightforward and easy to understand, and most of them are repeatedly revised and scrutinized.

Transitivity: The transmissibility of information breaks the limitations of time and space.

Features of the message:

Dependency: Information must be manifested in a certain medium.

Value: Information can meet people's needs in some ways.

Timeliness. Information changes with objective things.

Shareability: A piece of information can be shared by multiple points.

Transitivity: The transmissibility of information breaks the limitations of time and space.

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

The main characteristics of the information:

All information is stored and represented in binary form;

Information is the reduction or elimination of uncertain content;

Information is the content of interaction and mutual exchange with the outside world when the control system carries out adjustment activities;

Information is the state of movement of things and the form of state change;

Information is processed data that can influence the recipient's behavior and decision-making;

(1) Recognizable information is identifiable, and recognition can be divided into direct identification and indirect recognition, direct recognition refers to recognition through the senses, and indirect recognition refers to identification through various test means. Different sources of information have different ways to identify them.

2) Storability information can be stored in a variety of ways.

3) Expandability information will continue to expand over time.

4) Compressibility: People can condense and condense information by processing, sorting, summarizing, and summarizing it.

5) CommunicabilityThe communicability of information is the essential characteristic of information.

6) Convertibility information can be transformed from one form to another.

7) Scope-specific validity information is valid within a specific scope, otherwise it is invalid.

Information characteristics are the attributes and functions of information. Including: (1) dependency, (2) reproducibility (expansion), (3) deliverability, (4) storability, (5) shrinkability, (6) shareability, (7) scalability, (8) validity and invalidity, and (9) processability.

The characteristics of the information are:1. It has corresponding use value, and it can meet people's needs in some aspects.

2. Information is different from material resources. It can be transferred and shared by everyone. The more scientific and social norms the information, the more it is shared.

3. People summarize and synthesize a large amount of information, which is information condensation.

4. The information is valid if it meets the needs of the recipient, and is invalid if it is not; If it is needed at this time, it is valid, and if it is not needed at that time, it is invalid.

5. When a message is composed of multiple independent small messages, the amount of information contained in the message should be equal to the sum of the information contained in each small message.
