国家信息基础设施(NII)的全球挑战是要将不同的信息技术综合成一个快速、高效、互通性、可扩展、安全可靠、使用方便及接人面广的公共基础设施。NII的技术包括以下成份: ·计算机硬件、软件及中件 ·数据库、存储及图像系统 ·内容 ·电信 ·局域网及广域网 ·国际互联网络(Internet) ·卫星通信系统 ·蜂窝及无线系统 ·广播及有线电视 这些及其他NII技术的价值约占美国总投资的一半。虽然“NII”代表“国家信息基础设施”的概念。但它所代表的市场却越来越具有全球性的概念。当NIIT的成员谈“NII”时,他
The global challenge for the National Information Infrastructure (NII) is to bring together diverse information technologies into a single, rapid, efficient, interoperable, scalable, secure, easy-to-use and accessible public infrastructure. NII’s technology includes the following components: • Computer hardware, software and middleware • Database, storage and imaging systems • Content • Telecommunications • LANs and WANs • Internet • Satellite communications systems • Cellular and wireless systems • Broadcasting and wireline The value of these and other NII technologies in television accounts for about half of the total U.S. investment. Although “NII” represents the concept of “national information infrastructure”. But the market it represents is increasingly global in concept. When members of NIIT talk about “NII”, he
