2001年“9·11”事件的前一天,美国《福布斯》杂志的科技版发表了一组文章,预测信息技术的下一波大浪潮将在2004—2005年度出现。这一波浪潮的标志就是万维网(World Wide Web,WWW)升级为网格(Great Global Grid,GGG)。到2020年,由此产生的互联网将成长为一个20万亿美元产值的大产业。 网格(Grid)是近年来国际上兴起的一种重要信息技术,它是高性能计算机、数据源、互联网三种技术的有机组合和发展。综观近代科技发展史,从蒸汽机、发电机、电话到计算机,每一次根本性的变革总是伴随着依赖相关产品而形成的网格。例如,电的发明惟有经过电网的架设,才能照亮千家万户(电力网格);汽车等交通工具的发明只有经过公路、铁路等交通网的全面建设,才能投入使用(交通网格)。而当互联网上所有的资源实现全面连通时,也会像电力网、电话
The day before September 11, 2001, a series of articles published in the science and technology edition of Forbes magazine predicted that the next big wave of information technology will emerge in 2004-2005. The wave is marked by the World Wide Web (WWW) GreatGridGrid (GGG). By 2020, the resulting Internet will grow into a large industry with a GDP of 20 trillion U.S. dollars. Grid is an important information technology emerging internationally in recent years. It is an organic combination and development of three high-performance computers, data sources and the Internet. Looking at the history of modern science and technology, from steam engines, generators, telephones to computers, every fundamental change is always accompanied by a reliance on related products and a grid. For example, electric inventions can only illuminate tens of thousands of households (power grids) only through the erection of power grids. The invention of vehicles and other transportation vehicles can only be put into use (traffic grids) only after all-round construction of highways, railways and other transportation networks. And when all the resources on the Internet to achieve full connectivity, it will be like the power grid, telephone
