OSI 七层模型和TCP/IP模型及对应协议（详解）

OSI 七层模型和TCP/IP模型及对应协议（详解）先看图，有图有真相在OSI七层模型中，处于不同层的中继系统具有不同的名称。一个设备工作在哪一层，关键看它工作时利用哪一层的数据头部信息。网桥工作时，是以MAC头部来决定转发端口的，因此显然它是数据链路层的设备。具体说:物理层...

OSI七层模型与TCP/IP四层模型

4层吧网络接口层为以太网头网络层为ip头传输层为tcp/udp头应用层根据不同应用有http头,ftp头,telnet头等等或 4层应用层--数据 3层主机到主机层--数据段 2层internet层-数据包 1层网络接入层-帧/比特 OSI七层模型OSI中的层 ...
