本文档详细介绍了TCP\IP和OSI网络七层协议模型（内附精彩的插图，让人看了就一目了然）。

网络模型

计算机网络是指由通信线路互相连接的许多自主工作的计算机构成的集合体，各个部件之间以何种规则进行通信，就是网络模型研究的问题。网络模型一般是指OSI七层参考模型和TCP/IP四层参考模型。这两个模型在网络中应用最为广泛。

-This document details the TCP \ IP and OSI network protocol model seven (with wonderful illustrations, people looked on at a glance). Network model is the computer network connected by the communication lines of the work of many self-assembly consisting of a computer, between the various components to communicate the rules to what is the problem of network model. Network model generally refers to seven OSI Reference Model and TCP/IP reference model four. The two models in the most widely used network.
