如图2-1所示,是TCP/IP参考模型和OSI参考模型的对比示意图。图2-1 TCP/IP参考模型 2.1 TCP/IP参考模型的层次结构 TCP/IP协议栈是美国国防部高级研究计划局计算机网(Advanced Research Projects Agency Network,ARPANET)和其后继因特网使用的参考模型。ARPANET是由美国国防部(U.S.Department of Defense,DoD)赞助.....
Here are the five layers of the TCP/IP model: image.png Application Layer Key Responsibilities of the Application Layer The main job of the application layer is to enable end-users to access the Internet via a number of applications. This involves: Writing data off to the networkin a format...
1.2 Network Hardware(网络硬件) 从广义上讲,目前普遍使用的传输技术有两种,分别是广播式链路和点到点链路。 点到点(point-to-point)链路将一对单独的机器连接起来。在一个由点到点链路组成的网络中,为了从源端到达接收方,短消息必须首先访问一个或多个中间机器,这种短消息在某些情况下称为数据包或包1(packet)...
access layer of a TCP/IP network includes the networkinfrastructure(hardware and software components) necessary for interfacing with the network medium. It handles physical data transmission—using Ethernet and protocols such as the address resolution protocol (ARP)—between devices on the same network....
