“信息高速公路”是以高新技术为基础的,如果没有20世纪一些非常先进的科技成果和当前正在积极开发的一系列关键技术为基础,也就不会有“信息高速公路。” 与“信息高速公路”有关的高新技术很多,限于篇幅,这里我们只能选择其中主要的几种技术做一点简单的介绍。 光导纤维技术 以前我们都用电来通信,60年代初发现了一种神奇的光——激光之后,人们才想到可以用光来传输信息。
The “information superhighway” is based on high and new technology. Without the very advanced scientific and technological achievements of the 20th century and a series of key technologies currently under active development, there will be no “information superhighway.” And “Information Highway ”a lot of high-tech, due to space limitations, where we can only choose one of the main types of technology to do a little simple introduction. Fiber Optic Technologies We used to communicate with electricity before, and in the early 1960s we discovered a magical light - after the laser, people came to think of using light to transmit information.
