OSI模型 1.概念 开放式系统互联通信参考模型(英语:Open System Interconnection Reference Model,缩写为 OSI),简称为OSI模型(OSI model),一种概念模型,由国际标准化组织提出,一个试图使各种计算机在世界范围内互连为网络的标准框架。 2.分层及分层原理 分层原理: 根据不同层次,抽象分层 每层实现一个定义明确的功能 ...
"In OSI model control is passed from one layer to the other starting at application layer in one station, proceeding to the bottom layer over the channel to next station and back up the hierarchy" i.e. starting at the top layer information is passed to the lower layer until it reaches ...
OSI参考模型并不是完美的 由于他的层次划分过多,会话层和表示层的存在意义不大 所以就繁衍出了我们的TCP/IP模型,该模型简化了OSI参考模型 后续我会在TCP/IP四层模型中详细阐述每层作用
The OSI model provides a framework to allow different computer systems to communicate with each other. Learn more about the 7 Network layers of the OSI reference model.
The OSI model categorizes the computing functions of the different network components, outlining the rules and requirement needed to support the interoperability of the software and hardware that make up the network. In addition to understanding what the OSI model is, note that the OSI model ...
OSI Model: 7 Layers Explained in Computer Network with computer network tutorial, introduction, features, types of computer network, components, cables and connectors, Router, Intranet, Modem, Uses Of Computer Network, Hub, Software and Hardware, Securit
In this article Physical layer Data link layer Network layer Transport layer This article explores the Windows network architecture and how Windows network drivers implement the bottom four layers of the OSI model.For general information on all seven layers of the model, see the OSI model...
OSI Layer 3 - Network Layer In the seven-layer OSI model of computer networking, the network layer is layer 3. The network layer is responsible for packet forwarding including routing through intermediate routers, since it knows the address of neighboring network nodes, and it also manages qualit...
The main aim of Network layer in OSI Reference Model is to deliver packets from source to destination across multiple links (networks). Here we have listed all the functions performed by the Network layer.
No discussion of any network architecture is complete without at least a brief mention of the Open Systems Interconnection (OSI) Reference Model. Frankly, this description of networking is almost meaningless in terms of actually existing networks, but it is quite helpful in clearly identifying the ...
