信息高速公路是一个以光纤通信电缆为主体的大用户提供大量信息,并由通信网络计算机数据库以及各种电子产品组成的完备网络该文指出在技术上实现信息高速公路可分为三个层次:传输层次、网络层次和终端层次。三个层次都离不开多媒体技术,这种技术将计算机、通信和声象技术融为一体。又指出,在信息高速公路完善的地方,家庭不必再分别购买电视机、录象机、计算机、传真机、音响和电话等家用电器,而只需一台多媒体计算机。目前,在美国、欧共体以及日本正在实施着各自信息高速公路的宏伟计划,初步形成了三足鼎立的势态。我国有关部门已拟定分地区、划行业,有步骤地进行,已发展了金桥、金关和金卡工程。
The information highway is a complete network that provides a large amount of information to large users, mainly composed of optical fiber communication cables, and is composed of a communication network computer database and various electronic products. This paper points out that the information highway can be technically divided into three levels: Transmission level, network level and terminal level. The three levels are inseparable from the multimedia technology, this technology will be computer, communications and audio-visual technology into one. Also pointed out that in the information highway perfect place, the family no longer have to buy TV sets, video recorders, computers, fax machines, audio and telephone and other appliances, but only a multimedia computer. At present, the United States, the European Community and Japan are implementing grand plans of their respective information superhighways, initially forming a tripartite confrontation. Relevant departments of our country have drawn up sub-regions and designated industries and conducted them step by step. Jinqiao, Jin Guan and Gold Card projects have been developed.
