一、Internet概述 1.什么是信息高速公路 当今世界信息技术飞速发展。在信息社会里,信息是人们赖以生存的第一资源。信息的发送和获取,是通过通信网络实现的。我们可以将通信网络看作一条通道,通过这条通道来传递信息,这就是我们常说的“信息高速公路”。“信息高速公路”是借用人们十分熟悉的“高速公路”这个通俗易懂的概念来表述抽象概念—“国家信息基础设施(National Infomation Infrastracture)”。也即,信息高速公路是信息基础设施的一种形象比喻。而这条“信息高速公路”正是社会信息化的基础。
First, the Internet overview 1. What is the information highway in today’s world of rapid development of information technology. In the information society, information is the first resource on which people depend. The sending and getting of information is realized through the communication network. We can think of the communications network as a passage through which information is transmitted, which is what we often refer to as the “information superhighway.” The “Information Highway” is an abstract concept that uses the straightforward concept of “highway,” which people are all familiar with - “National Information Infrastructure (National Infomation Infrastracture).” That is, the information highway is an image metaphor for information infrastructure. This “information highway” is the basis of social informatization.
