One helpful way is to think of the national information infrastructure as a network of highways,much like the INTERSTATES of the 1950s.
一种有用的方法是把国家信息基础设施想像为50年代州际高速公路网络。
These are highways carrying information rather than people or goods.

Second,the makers of information appliances,like telephones,televisions and computers,and the new products of the future that will combine aspects of all three.
第二是信息设施的生产厂家，这些设施诸如电话，数字化图书馆，信息服务提供者以及几百万希望共享或出售信息的单个用户。
Third information providers;local broadcasters,digital libraries,information service providers and millions of individuals who will want to share or sell information.
第三是信息的提供者：本地广播电台，数字化图书馆，信息服务提供者以及几百万希望共享或出售信息的单个用户。
