Datagram – Layer 3: This term is basically synonymous with “packet” and is also used to refer to network layer technologies. It is also often used to refer to a message that is sent at a higher level of the OSI Reference Model (more often than “packet” is). Frame – Layer 2: ...
The ISO Open Systems Interconnection (OSI) Reference model describes networking as "a series of protocol layers with a specific set of functions allocated to each layer. Each layer offers specific services to higher layers while shielding these layers from the details of how the services are ...

A well-defined interface between each pair of adjacent layers defines the services offered by the lower layer to the higher one and how those services are accessed." The following diagram illustrates the OSI reference model.In Windows 2000 and later, network drivers implement the bottom four ...
There's also a somewhat simpler four-layer Defense Advanced Research Projects Agency (DARPA) model that maps to the OSI model, but the OSI version is the most commonly referred to. I'll reference both models when discussing the various layers. The following diagram compares the OSI and DARPA...

开放式系统互联通信参考模型(Open System Interconnection Reference Model),简称为OSI,是一种概念模型,试图使各种计算机在世界范围内互连为网络的标准框架。 一、物理层 物理层(Physical Layer)在局部局域网上传送数据帧(data frame),它负责管理计算机通信设备和网络媒体之间的互通。包括了光纤、针脚、集线器、中继器等。
The OSI reference model is not a standard, but aconceptual framework that is used when setting standards. The OSI model is compared tothe TCP/IP model TCP/IP model is actually acondensed version of the OSI model, it only has four levels: 1. The applicationlayer (2) transport layer (3)...
