信息高速公路信息高速公路是国家信息基础设施的形象比喻。实际上,它是一个巨型的交互式多媒体高速计算机通信网络系统。它将原来分散的电话、计算机、电视、广播、传真、数据库等传输系统集成为一体。形成以现代计算机网络通信技术为基础,以光导纤维通信和卫星通信为骨干,以数据库为信息源,跨越全国各地乃至世界各国的双向大容量、高速度的数字化数据传输系统。这种由多种通信网络、大量计算 Information Highway The Information Highway is an image metaphor of the national information infrastructure. In fact, it is a giant interactive multimedia high-speed computer communication network system. It will be the original scattered telephone, computer, television, radio, fax, database and other transmission systems into one. The formation of a modern computer network communications technology as the basis to optical fiber communications and satellite communications as the backbone to the database as a source of information across all parts of the country and even countries around the world bidirectional large-capacity, high-speed digital data transmission system. This kind of communication network, a large number of calculations
