The Information Age is an era of fundamental and global change in intellectual, philosophical, cultural and social terms. Today's Information Age began with the telegraph. It was the first instrument to transform information into electrical form and transmit it reliably over long distances. New techniques of encoding and distributing digital information are promoting the progress of the Information Age throughout society.

2. Information superhighway

A name first used by former US vice-president Al Gore for the vision of a global, high-speed communications network that will carry voice, data, video, and other forms of information all over the world, and that will make it possible for people to send e-mail, get up-to-the-minute news, and access business, government and educational information. The Internet is already providing many of these features, via telephone networks, cable TV services, online service providers, and satellites. In the US, the information superhighway is also known as National Information Infrastructure. The information superhighway can be understood to be a highway which has computer technology and modern telecommunications technology serving as the base of the road and fiber-optic cables serving as the surface of the road. The "vehicles" are the multimedia machines equipped with computer, television and telephone, and high speed transmission and exchange of various multimedia information form the web covering the whole nation. If the national superhighways all over the world are linked together, the global information superhighway will be created.
