Communication technology application scope

Communication is the nervous system of the country and modern society, and the communication industry itself is the basic structure and pioneer industry of the national economy.

Communication technology has developed with the development of society and human needs; in turn, the development of communication technology plays a huge role in promoting the development of society.

Communication technology is recognized as the "accelerator" of national economic development and the "multiplier" of social benefits. Modern communication technology is the "catalyst" that changes people's lifestyles. ” is the lifeline of the information age and information society. Its function can be manifested in the following aspects.

1. The communication industry has a promotion role in the development of other industries. It can drive the rapid development of various sectors of the national economy, thus producing huge economic benefits. For example, the total investment in the advanced communication network built by Japan in 1995 was US$800.12 trillion. The economic ripple benefits generated by the production activities of various departments of the national economy could reach US$400 billion, and its growth coefficient was 3 .3～5. Dr. Hardy from the United States has studied and counted the relationship between the increase in telephone penetration rate and the resulting national economic growth in more than 50 developed and developing countries. His conclusion is: if the telephone penetration rate increases by 1% in the first five years, the average per capita increase in the telephone penetration rate in the next seven years will be The gross national product can be increased by 3%.

In short, the communication industry and communication undertakings play an important role in promoting the development of various industrial sectors of the national economy, such as transportation, energy, aviation, railways, water conservancy, finance, radio and television, etc.

2. Communication development can shorten the span of time and space and speed up capital turnover

Communication technology can improve the operational efficiency and capabilities of various equipment, especially in contemporary times, with the internationalization of economic relations and the globalization of data exchange , allowing developed countries to allow funds to travel around the world through internationally interconnected data communication networks.

For example, some consortiums in the United States, Japan and other countries take advantage of the time difference between the Eastern and Western Hemispheres to allocate funds through communication means, so that the funds can be fully utilized within 24 hours.

3． The development of communication technology can significantly ease the pressure on transportation, greatly reduce the flow of people and the total amount of physical goods, and save energy consumption. The use of communication means can replace business trips and contact work and information. Obtain. According to statistics, the energy saved every day in China is 7% of the daily consumption. It also reduces exhaust gas and noise pollution and protects the ecological environment.

4． Communication can realize the sharing of databases and other resources, providing more successful opportunities for economic development

In the information society, information is not only a resource, but also a capital and a product. Through data communication networks and computer communication terminals connected to databases, scientific research institutes and large and small enterprises can quickly obtain valuable data to serve for decision-making in scientific research and production.

5. Communication can promote the improvement of labor productivity and work efficiency

According to reports, the latest clothing design information in Paris, France can be displayed on a computer in Guangzhou in just 1 minute through the Internet. In less than an hour, the latest designs are on display in the shop window.

This example shows that communication has improved productivity and work efficiency to an astonishing degree. According to a survey of 440 occupations in 201 industries in the United States, the value created by the information industry accounts for 48% of the U.S. national economy. With the rapid development of modern communication technology and computer technology, labor productivity will surely be further improved.

6． The combination of communication technology and computer technology has turned modern warfare into "electronic information warfare"

Communication technology has become a key factor in winning modern information wars.

The Gulf War in 1991 was the prototype of electronic information warfare. In the past, wars were filled with smoke. On the battlefield, aircraft and tanks were the core, and the opponent was defeated by destroying the opponent's body and equipment. Modern war is silent, and the battlefield is based on computer communication technology, which is to destroy the enemy's " "nerve center" system to win the war.

On the battlefield, the enemy's combat effectiveness can be eliminated at the moment when no aircraft can be seen or the sound of artillery can be heard. Modern war is a competition between the two sides in the development of high-tech aspects such as communication technology and computer technology. Whoever has high-tech will win.

7． The development of communication technology is changing the past way of life of mankind

In the modern information society, people are engaged in frequent information exchanges all the time. Information exchange has become an indispensable "necessity" in people's daily lives. With the development of |internet, surfing the Internet has become an important way for people to obtain and exchange information. Sending and receiving emails, surfing the Internet, downloading files, and online shopping have become part of people's lives;

"Home office" and "electronic money" have become today's fashion; "distance education" and "telemedicine" are quietly emerging... All of these are changing human beings' lifestyles and making people's lives more colorful and happy. hapiness.

8. Modern communication technology provides government agencies, enterprises and institutions with a fast, efficient, flexible and convenient working platform

In short, in the information society, human behaviors, concepts and ways of living, learning and working will all change Profound changes occur. As the lifeline of the information society, communication will become the "nervous system" of modern society. The ever-changing communication technology and various communication methods are closely related to everyone.

Therefore, understanding the formation and development of communication technology, being familiar with the simple principles and main applications of communication methods, and understanding the characteristics and functions of modern communication tools will have an extremely positive impact on improving people's quality of study, work, and life. It is also a necessary preparation for people to enter the information age and adapt to human progress and social development.
