Information Processing

Information is neither a substance nor an energy.

Information Processing

It is a general term for exchanging content with the external environment when humans adapt to the external environment and when they are coping with the external environment.

Therefore, it can be considered that information is a semaphore of an interactive communication between a person and the outside world.

Information is something that can be used to eliminate uncertainty and is a negative value of the logarithm of the probability of occurrence of an event.

Information processing is the reception, storage, conversion, transmission and release of information.

Information is inextricably linked to our daily work.

The process of computer information processing is actually consistent with the process of human information processing.

Information processing is first obtained through sensory organs, and information is transmitted and stored through the brain and nervous system.

Finally, the information is published by words, lines or other forms.

Introduction

Information is both an abstract concept and a ubiquitous actual event.

Norbert Wiener, the cybernetic founder, believes that information is neither material nor energy. It is a general term for humans to exchange content with the external environment when they adapt to the external environment and when they are coping with the external environment.

Therefore, it can be considered that information is a semaphore of an interactive communication between a person and the outside world.

Information processing is the processing of the collected information to falsify the truth, to extract the fine, from the outside to the inside, and from this to the other.

It is based on the original information, and produces an activity process with high value and convenient secondary information.

This process will add value to the information.

Only when information is properly processed can new information or knowledge be used to guide decision making.

Function and use

According to Clause Shannon, the founder of information theory, information is something that can be used to eliminate uncertainty, and is a negative value of the logarithm of the probability of occurrence of an event.

For the first time, this discussion clarifies the function and purpose of information, indicating that information is a measurable concept, and points out that the measurement method of information can be determined according to the probability of occurrence of the corresponding event.

In this way, different probability practices include different degrees of influence (or amount of information).

Information processing is the reception, storage, conversion, transmission and release of information.

With the continuous development of computer science, computers have evolved from an initial computing tool based on “computation” to information processing, integrating computing and information processing, working with people, learning and A tool that is inseparable from life.

The above concepts may be too abstract.

In fact, information is everywhere in everyday life.

For example, in the field of computer information processing, information can be classified into text information, multimedia information, and hypermedia information from the form of information that can be processed by a computer.

From the perspective of the degree of structure of information, information can be divided into structured information, semi-structured information and unstructured information.

In the field of information security, information has public information, general confidential information, and top secret information.

Therefore, information is inseparable from our daily work.

Further analyzing the process of computer information processing, it can be seen that the reception of information includes information perception, information measurement, information identification, information acquisition, and information input.

The storage of information is to buffer, save, backup, etc. the received information or the information in the middle of conversion, transmission or distribution through the storage device.

Information transformation is the process of classifying, calculating, analyzing, retrieving, managing and synthesizing information according to people’s specific needs.

The transfer of information transfers information from one place to another through a network of instructions within the computer or between computers.

The release of information is to display the information in various forms.

The process of computer information processing is actually consistent with the process of human information processing.

Information processing is first obtained through the sensory organs. Information is transmitted and stored through the brain and nervous system, and finally information is released through words, lines or other forms.
