What the message represents 10

The concept of information: the object of transmission and processing of audio, message and communication system, generally refers to all the content of human social communication. 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.

Information is a reflection of the state of motion and changes of various things in the objective world, a representation of the interconnection and interaction between objective things, and a manifestation of the essence of the state of motion and changes of objective things.

Physically speaking, information and matter are two different concepts, information is not matter, although the transmission of information requires energy, but information itself does not have energy. The most significant feature of information is that it cannot exist independently, and the existence of information must rely on carriers.

1. The larger the probability of message occurrence p(x), the smaller the amount of information; Conversely, the smaller the probability of occurrence, the greater the amount of information. It can be seen that the amount of information (which we denote as i) and the probability of a message occurring are inversely related.

2. When the probability is 1, 100% of what happens is known to everyone on the earth, so the amount of information is 0.

3. 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 is a term in information theory, and what makes sense in a message is often referred to as information.

Answering 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. Information is a collection of things and their property identities. Information is a manifestation of the state of motion and the way things exist.

Information is some form of data that has been processed, has meaning to the person receiving it, and has practical or perceived value in current or future actions and decisions.

Information technology refers to the technology of collecting, identifying, extracting, transforming, storing, transmitting, processing, retrieval, testing, analyzing and utilizing information. Any work unit that deals with these processes and technologies can be referred to as an information department.

Information technology is capable of extending or extending a person's information capabilities. Information technology may be mechanical or laser; It could be electronic, or it could be biological. Information technology mainly includes sensing technology, communication technology, computer technology and microfilm technology.

The task of sensing technology is to prolong the function of the human sensory organs to collect information; The task of communication technology is to prolong the function of the human nervous system to transmit information; Computer technology is to extend the function of human thinking organs to process information and make decisions, and microfilm technology is to extend the function of human memory organs to store information. Of course, this division is only relative and approximate, and there is no clear boundary. For example, there is also the processing and collection of information in the sensing system, and there is both information transmission and information collection in the computer system.

Resources.

The meaning of the information is: the specific content of the transformation process of different energies of various things.

Knowledge or messages expressed in a form suitable for communication, storage, or processing.

The word "information" has a long history, as early as more than 2,000 years ago in the Western Han Dynasty, the word "letter" appeared. "Faith" can often be understood as a message. As an everyday term, "information" often means "audio, news", but there is still no accepted definition of information.

Information is the indication of matter, energy, information and its properties. [2006, Medical Informatics (Journal)]. Information is an increase in certainty.

Information is a collection of phenomena of things and their property identification. Information is transmitted and reflected in the material medium as a carrier, and the representation of the mode of existence and movement of various things in the world is transmitted. Information is the sum of the laws of motion of matter, and information is neither matter nor energy!
