OSI参考模型,全称为开放系统互联参考模型(Open Systems Interconnection Reference Model),是国际标准化组织(ISO)制定的一个网络通信协议的概念模型。它定义了计算机系统在通信过程中应遵循的标准和规范,将通信过程分为七个层次,并对每个层次的功能和协议进行了详细的描述。 OSI模型的七个层次是: 1. 物理层(Physical ...

ISO 7 layer model Physical The lowest layer of the OSI Model is concerted with electrically and optically transmitting raw unstructured data bits across the network from physical layer of the sending device to the physical layer of receiving device. It can include specifications such as voltages. ...

OSI model (OpenSystemsInterconnection model) The International Standards Organization's OSI model serves as a standard template for describing a network protocol stack (seeOSIandISO). For comparisons between the OSI model and other protocol stacks, seeTCP/IP,SDVoE,ATM,NetWare,SNAandSS7. ...
Within the OSI model, the Data Link layer was split into two, the Media Access Control (MAC) sub-layer and the 802.2 Logical Link Control (LLC) sub-layer. You can make up expressions to remember the order of the 7 layers, for example, 'Angus Prefers Sausages To Nibbling Dried Pork' ...
In the seven-layer OSI model of computer networking, the physical layer or layer 1 is the first and lowest layer. The implementation of this layer is often termed PHY. The physical layer consists of the basic networking hardware transmission technologies of a network. It is a fundamental layer...
