What needed was a network of interconnected networks. This led to the idea of “internetworks” or “internet”. 说了这么多令人费解的话，我们还是回到现实中来吧。尽管ARPA网计划的目标是要开发一张巨大的网络来连接相距遥远的子网主机，但经验表明单独的一个网络无法为每个需要服务的人提供服务。我们所需要的是一个把各个网互相连接在一起的网络，这就引出了网际网的概念。 An extranet is a private network that uses the Internet protocols and the public telecommunication system to securely share part of a business’s information or operation with suppliers, vendors, partners, customers or other businesses.
