读过关于网络的课程的，都知道ISO-OSI 7层协议这个名词，许多书籍都会具体的画出那幅图，然后标注上物理层，数据链路层，网络层等等.背的大家要死.但是却又不知道具体这些层次干吗用的勒？
其实在互联网中，由于实际使用的是TCP/IP模型，也就是DOD模型(现在不知道没关系，后面会说).所以7层模型在现实网络环境中只是一个理论上，学究派的东西.这个模型中，我们真正关心的是下面的3层.
1.物理层 .哦.是的.这个名词还算容易了解.网卡还有那些网线构成了这一层.那些在网线中传播的二进制数据流是这层的具体表象.也就是说，这一层上面没有什么协议(不是很的说法，但是你可以这么理解).有的都是电流而已.我们把两台机器用网线连起来.或者用HUB把机器都连起来，这些工作就是物理层的工作.
