计算机英语会话(MP3+中英字幕) 第40期:信息高速公路(5)

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.只不过这种高速公路运载的是信息而不是人或货物。Some highways will be made of fiber optics,others of coaxial cables,others will be wireless.某些高速公路将采用光纤，而其它的用同轴电缆，还有的用无线通信。But this is a key point:they must and will be two-way highways.但是关键的一点是：必须是双向高速公路。So that each person will be able to send information in video form as well as just words,as well as receiving information.这样，每个人能够发送视频信息和文字，同时能接收信息。These new information highways will be wider than today's technology permits.这些新的信息高速公路将比当前技术所能达到的要宽。That's because of television program contains so many more bytes of information than a telephone conversation.这是因为电视节目比电话通话所包含的信息字节多得多。And because new uses of video and voice and computers will consist of even more information moving at even faster speeds.也还因为新投入使用的视频和话音设备以及计算机将包含以更高速流动的信息。This new information market place based on these highways include four major components.这种基于高速公路的新信息市场包括四个主要部分：First,the owners of the highways,because unlike the interstates,the information highways will be built,paid for and funded principally by the private sector.首先是高速公路的拥有者，与州际高速公路不同的是，信息高速公路将主要由私人投资建设。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。And most important,fourth,information customers,who will justly demand privacy?Afford ability and choice.第四是最重要的信息的客户，他们将正当地要求隐私权，可承受性和选择权。At some time in the next two decades,we will think about the information market place in terms of these four components.今后二十年的某个时候，我们将从四个方面去考虑信息市场。We will not talk about cable,or telephones,or cellular,or wireless,because there will be free and open competition between everyone who provides and delivers information.我们不会讨论电缆，电话或蜂窝式电话或者无线电话，因为在任何信息提供和发送信息者之间的竞争是自由的，公开的。Notes注意事项We will not talk about cable,or telephones,or cellular,or wireless,because there will be free and open competition between everyone who provides and delivers information.我们不会讨论电缆，电话或蜂窝式电话或者无线电话，因为在任何信息提供和发送信息者之间的竞争是自由的，公开的。
