Language is the first carrier for human beings to transmit information, a tool for social communication and exchange of ideas, and the most convenient, complex, universal and important information carrier system in human society. With the development of production and the continuous progress of society, the second carrier of information appears: words. There are more than 500 languages in use in the world.

The invention of writing makes it possible to store (record) and transmit information at a long distance, which is a great progress of mankind. With the invention of telegraph, telephone and radio, a large amount of information has spread at the speed of light, connecting the whole world, and human information activities have entered a new era. With the huge increase of information, information is widely exchanged, which requires a larger capacity information carrier.

New information carriers such as computers, optical fibers and communication satellites have become the main information carriers of the new technological revolution. A hair-thick optical fiber can transmit hundreds of thousands of telephones or thousands of televisions at the same time. The new information carrier will inevitably lead to a new information revolution.
