1, language creation.

It happens when apes become people. Labor has created human beings, and human beings have created language, acquired a unique material means of information exchange and acquired a unique concept of tools for processing information.

2. The invention of writing.

Happened at the end of primitive society. It makes human information transmission break through the direct transmission mode of spoken language, so that information can be stored in words and spread for a long time beyond the direct time and space boundaries.

3. The invention of papermaking and printing.

This is a change in feudal society. This invention has expanded the capacity and scope of information exchange and transmission, and enabled human civilization to spread rapidly.

4. The invention of modern communication technologies such as telegraph, telephone and television.

It happened at the end of 19 and the beginning of the 20th century. These inventions have fundamentally changed the means of information dissemination, accelerated the speed of information dissemination, shortened the time and space scope of information, and information can spread all over the world instantly.

5. Invention and application of electronic computing.

The appearance of computers in the mid-20th century fundamentally changed the information processing methods of human beings, broke through the limitations of human brain and sensory organs in processing information, and greatly enhanced the ability of human beings to process and utilize information.

Extended data

Development trend:

1, the earth changes.

Due to the cross-border nature of information technology itself, traditional geo-economy, geo-culture, geo-military and geo-politics are giving way to modern network economy, network culture, network military and network politics.

2. the west is integrated into the east.

Because the information technology revolution will once again divide the world's wealth in three dimensions, the western hemisphere economic circle, as the birthplace of the technological revolution, is increasingly infiltrating into the eastern hemisphere economic circle, which is warm and cold at first sight.

At the same time, the countries in the Eastern Hemisphere upgrade their industrial structure with the help of the information revolution, in order to get rid of the "colony" that will become a new round of global network enclosure war in the next century, and also actively introduce advanced western technologies in desperation.

3. Cong has become stupid.

Since the information technology revolution has expanded from a single information technology industry to a cross-industry revolution, more and more smart people have continuously introduced "fool version" information technology products to face ordinary people who are hundreds of times more skilled than users.

4. Narrow and widen.

The e-commerce revolution triggered by the information technology revolution has put forward huge market demand for the global information infrastructure to move towards the transmission channel of end users. No matter in the telecom infrastructure layer, access service layer or business application layer, the bandwidth has become wider and wider, which has become an important factor in winning the competition.

5. Make the point straight.

Because the information technology revolution can connect manufacturers and end users anytime and anywhere. The traditional distribution agency system is being impacted by the direct selling interactive system.

6. Close and open.

When the trend of global information technology revolution spreads to China and other developing countries, it is necessary to properly handle the relationship between equality and inequality between technology leading countries and technology receiving countries, as well as the realistic relationship between the differences in political systems between the East and the West and the widening gap between the rich and the poor between the North and the South. Sound information technology policies are very important to developing countries, and it may be wise to make rules before opening up.

7. Technology changes into trade.

In the new century, the "network-building right" war, which is induced by the information technology revolution, has started in the form of global electronic trade and the essence of competing for the commanding heights of global wealth.
