嵌入式TCP-IP协议单片机技术在网络通信中的应用

计算机网络由一组结点和链络构成。网络中的结点有两类：转接结点和访问结点。通讯管理机、集中器和终端控制器等归于转接结点，它们在网络中转接和交换传送信息。主计算机和终端等是访问结点，它们是信息传送的源结点和政策结点。

(A computer network consists of a set of nodes and links. There are two types of nodes in the network: transit nodes and access nodes. Communication management machines, concentrators and terminal controllers, etc. belong to the transfer nodes, which transfer and exchange information in the network. The host computer and the terminal are the access nodes, which are the source nodes and policy nodes for information transmission.)
