因特网的由来及发展 因特网起源于1969年美国国防部先进计划研究局(DARPA),作为军用技术能够达到有关单位信息共享的目的,开始利用信息件交换(package switching)技术,建立先进研究计划信息网,简称ARPAnet。在1975年,为了便于与美国各地网络联网。制定了一些网络标准协议,以便使入网单位共同遵守。后来采用‘协议’的名称命名该网,即为世界驰名的因特网(Internet)。1986年美国科学基金会(NSF)所属五个超级计算中心加入ARPAnet,成为后来因特网的骨干。1994年ARPAnet改变为国家研究与教育网(NREN)。该网的T1线作
The Origin and Development of the Internet The Internet originated in 1969 by the Defense Advanced Research Projects Agency (DARPA), which, as a military technology, can achieve the goal of information sharing among relevant agencies. It has begun to use the technology of information exchange (package switching) to establish an advanced research program information network , Referred to as ARPAnet. In 1975, in order to facilitate networking with the United States throughout the network. A number of network standards agreements have been developed to allow the network operators to comply. Later, the name of the agreement ’name the network, the world famous Internet (Internet). In 1986, five supercomputing centers affiliated with the NSF joined ARPAnet and became the backbone of the Internet. ARPAnet changed to National Research and Education Network (NREN) in 1994. The network’s T1 line made
