The Beginning - ARPAnet
The Internet started as a project by the US government. The object of the project was to create a means of communications between long distance points, in the event of a nation wide emergency or, more specifically, nuclear war. The project was called ARPAnet, and it is what the Internet started as. Funded specifically for military communication, the engineers responsible for ARPANet had no idea of the possibilities of an "Internet."
By definition, an 'Internet' is four or more computers connected by a network.
ARPAnet achieved its network by using a protocol called TCP/IP. The basics around this protocol was that if information sent over a network failed to get through on one route, it would find another route to work with, as well as establishing a means for one computer to "talk" to another computer, regardless of whether it was a PC or a Macintosh.



Internet的历史
起源——ARPAnet
Internet是被美国政府作为一项工程进行开发的。这项工程的目的,是为了建立远距离之间点与点的通信,以便处理国家军事范围内的紧急事件,例如核战争。这项工程被命名为ARPAnet,它就是Internet的前身。建立此工程的主要应用对象就是军事通讯,那些负责ARPAnet的工程师们当时也没有想到它将成为“Internet”。
根据定义,一个“Internet”应该由四或者更多的计算机连接起来的网络。
ARPAnet是通过一种叫TCP/IP的协议实现连网工作的。此协议最基础的工作原理是:如果信息在网络中的一条路径发送失败,那么它将找到其他路径进行发送,就好象建立一种语言以便一台计算机与其他计算机“交谈”一样,但不注意它是PC,或是Macintosh。
