What are the characteristics of useful information, and what are the characteristics of information?

1) High quality.

Quality is the most important characteristic of information. It is difficult to imagine how useful information may be if it is not of high quality. The requirements for quality can be subdivided into several requirements.

High-quality information must be precise. If the information does not accurately reflect the current situation, it will certainly not yield good results by using this information for decision-making or control. Clarity is another requirement for high-quality information, and the meaning and content of the information must be clear to the manager.

High-quality information is organized, not disorganized.

The medium through which information is transmitted has a significant impact on quality. For example, handing over a large stack of paper to a manager instead of a few pages of a summary report is an inappropriate way to deliver it.

2) Timely. Most management requires timely information. Many day-to-day tasks are time-sensitive, such as decisions about how an organization responds to the environment must be made quickly.

Information is available when it is needed, so that managers have the information they need to help get the job done. For example, a manager can ask a subordinate to submit an exception report, which is generated when things go out of the ordinary.

In this way, if production on the production line falls below a certain level for some reason, such as a failure, an exception report is generated and those who need to be informed are notified so that they can take appropriate action, such as making repairs and adjustments, to eliminate the fault.

The information should reflect the current situation. The information provided to managers should be current, not from some time in the past. Timely information requires that information be made available to managers frequently.

For example, a periodic reporting system should be established, with daily, weekly, monthly or quarterly reports produced and submitted.

3) Completely. If the information contributes to the effective completion of the management work, then it must be complete.

The scope of the information must be broad enough to enable managers to have a more complete picture of the current situation and to take effective measures. When possible, managers need to have access to not only current information, but also the organization's past history and future plans. Brevity and detail are two other requirements for completeness.

This seems a bit contradictory, as brevity and detail are antithetical. But on closer analysis, this is not the case, and a balance can be found between conciseness and detail.

Information should be presented to managers in the most concise manner possible, but it should also be as detailed as possible so that managers have a certain depth and breadth of understanding of the current situation. However, too much detail can distract managers from important information. Finally, only information that is relevant to the management work at hand needs to be provided, and it is not good to provide too much information.

1) High quality; (2) timely; (3) Complete and relevant.

First of all, it must be of high quality;

Second, it must be timely and available to managers when they need it;

Finally, it must be complete and relevant.

The characteristics of information are dependence, value, timeliness, sharing, and transmission.

1. Dependency (information must be manifested by adhering to a certain medium);

2. Value (information can meet people's needs in some aspects);

3. Timeliness (information will change with the change of objective things);

4. Shareability (a piece of information can be shared by multiple points);

5. Transitivity (the transmissibility of information breaks the limitations of time and space).

Origin of the name of the message:

The word "information" is "information" in English, French, German, and Spanish, and "intelligence" in Japanese. It first appeared as a scientific term in Hartley's 1928 article "The Transfer of Information.

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 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.

Characteristics of information:

1. Dependency. Matter is a concrete, tangible resource; And information is an abstract, intangible resource. Information must be attached to a material carrier, and only a carrier with a certain amount of energy can transmit it.

Information cannot exist independently of matter and energy. News information cannot be reflected without facts, language, and newspaper layouts that have a certain time and space.

2. Reproducibility. Material and energy resources are reduced as long as they are used; However, the information is constantly expanding, regenerating, and never running out. In today's world, on the one hand, there is an "energy crisis" and a "water crisis", and on the other hand, there is a "surge in information".

3. Deliverability. If there is no transmission, there is no information. There are many ways to transmit information, such as oral language, body language, hand-copied text, printed text, telecommunication signals, etc.

4. Shelvability. Information may be stored for other purposes or for use by others. There are various means of storing information, such as human brain, computer memory, writing, printing, microfilming, video recording, photographing, audio recording, etc.

5. Shrinkability. People summarize and synthesize a large amount of information, which is information condensation. For example, summaries, reports, proposals, news reports, experience, knowledge, etc. are all refined after collecting a large amount of information.

Microfilms, optical discs, etc., are modern technologies for condensing and storing information.

6. Shareability. 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. News and information can only have a universal effect if it is highly shared.

7. Availability. That is, to derive the form of future information from current information. Information is a pre-reflection of reality and reflects the development trend of things. This is where the value of information lies in the "judgment" and even the "decision".

8. Validity and invalidity. The information is valid if it meets the needs of the recipient, and if it does not, it is invalid; If it is necessary at this time, it is valid, and if it is not required at that time, it is invalid; What works for this person may not be effective for others. News information mainly meets the general needs of the audience with timeliness, freshness, significance, proximity, and interest, so as to obtain effectiveness.

9. Processability. If information is analyzed and processed by humans, new information is often generated, so that the information can be value-added.

10. As a special resource, information has corresponding use value, and it can meet people's needs in some aspects. However, the value of information is relative, and it depends on the need to receive information and the ability to understand, recognize and use information.

1. In the information society, information and knowledge have become important factors of productive forces, and together with material and energy, they constitute the three major resources on which society depends.

2. The economy of the information society is dominated by the information economy and the knowledge economy, which is different from the agricultural society that is dominated by the agricultural economy and the industrial society is dominated by the industrial economy.

3. In the information society, the knowledge of workers has become the basic requirement.

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 necessary at this time, it is valid, and if it is not required 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.

Information has many basic characteristics, such as: universality, objectivity, dependence, sharing, timeliness, transmission, etc. The following is a description of some of the main characteristics of information and discussion and exchange to further recognize and understand the concept of information.

Universality and objectivity.

In both nature and human society, things are constantly evolving and changing. The message expressed by things is also omnipresent at all times. Therefore, information is also ubiquitous.

Since the development and change of things are not subject to the subjective consciousness of human beings, information is also objective.

Dependency. Information is not a concrete thing, nor is it a substance, but an attribute of an objective thing. Information must be attached to something objective (**) in order to exist.

The same information can be expressed with the help of different information**, such as: text, graphics, images, sound, film and animation, etc.

Shareability. Information is also a resource that has use value. The wider the area of information dissemination and the more people who use it, the greater the value and role of information.

In the process of copying, transmitting, and sharing information, copies can be repeatedly generated. However, the information itself does not diminish or be consumed.

Timeliness. As things evolve and change, so does the usable value of information. Over time, information may lose its usefulness and may become invalid.

This requires that people must obtain and use information in a timely manner, so as to reflect the value of information.

Transitivity. Information can be transmitted in space through the transmission of **. Such as:

The live broadcast of the space rendezvous and docking of China's manned spacecraft "Shenzhou 9" and "Tiangong-1". To introduce the development process of China's aerospace industry to people throughout the country and around the world. It shortens the distance between the docking site and the TV audience, and realizes the transmission of information in space.

Information can be transmitted in time through the storage of **. For example, those who have not been able to see the live broadcast of the space rendezvous and docking of "Shenzhou 9" and "Tiangong-1" can watch it in the form of playback or replay.

This is to take advantage of the solidity of information storage, and realize the transmission of information in time.

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 transitivity 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.
