The so-called "information highway" is a high-speed, large-capacity, multimedia information transmission network. Its speed was 10,000 times higher than the transmission speed of the network at that time; its capacity was large, and one channel could transmit about 500 TV channels or 500,000 telephones. In addition, the sources, content and forms of information are diverse.
