Internet-“冷战”的产物-1957年10月和11月，前苏联先后有两颗“Sputnik”卫星上天-1958年美国总统艾森豪威尔向美国国会提出建立DARPA（Defense Advanced Research Project Agency），即国防部高级研究计划署，简称ARPA-1968年6月DARPA提出“资源共享计算机网络”（Resource Sharing Computer Networks），目的在于让DARPA的所有电脑互连起来，这个网络就叫做ARPAnet，即“阿帕网”，是Interne的最早雏形早期的ARPAnet使用网络控制协议（Network Control Protocol，NCP），不能互联不同类型的计算机和不同类型的操作系统，没有纠错功能1973年由Kahn和Vinton Cerf两人合作为ARPAnet开发了新的互联协议。1974年12月两人正式发表第一份TCP协议详细说明，但此协议有信包丢失时不能得到有效的纠正TCP协议分成了两个不同的协议：-用来检测网络传输中差错的传输控制协议TCP-专门负责对不同网络进行互联的互联网协议IP从此TCP/IP协议诞生1983年ARPAnet上停止使用NCP，互联网上的主机全部使用TCP/IP协议，TCP/IP协议成为Internet中的“世界语”
