TCP/IP is a functional model designed to solve specific communication problems, and which is based on specific, standard protocols. OSI is a generic, protocol-independent model intended to describe all forms of network communication. In TCP/IP, most applications use all the layers, while in OSI...
This tutorial is the third part of the article. It compares the OSI reference model with the TCP/IP model and lists the similarities and differences between both. TCP/IP Reference Model Explained This tutorial is the fourth part of the article. It explains the five layers of the TCP/IP mod...
7 Layers of OSI Model The OSI model is divided into seven layers to represent network architecture. Each layer performs its own set of tasks and communicates with the layers above and below it to carry out successful network transmission. Let us discuss all of the layers and their properties ...
The OSI layer model explained If you've ever heard an IT student muttering, "A priest saw two nuns doing pushups," you've heard about the OSI layer model. The terms are a bit technical, and students often struggle to remember them. But dig in, and you'll discover that the layers a...
The 7 layers of the OSI model Cross-layer functions Cross-layer functions, or services that may affect more than one layer, include the following: security service telecommunication as defined by the International Telecommunication Union Standardization Sector (ITU-T) X.800 recommendation; ...
OSI Model Explained: The OSI 7 Layers We’ll describe OSI layers “top down” from the application layer that directly serves the end user, down to the physical layer. 7. Application Layer The application layer is used by end-user software such as web browsers and email clients. It provide...
Windows 网络驱动程序 实现OSI 模型的底层四层。 物理层 物理层是 OSI 模型的最低层。 此层管理非结构化原始位流通过物理介质的接收和传输。 它描述了与物理介质的电气/光学、机械和功能接口。 物理层承载所有较高层的信号。 在Windows 中,网络接口卡 (NIC) 实现物理层、其收发器和 NIC 连接到的介质...

In order for the OSI model to work as described, despite the greatest possible freedom with regard to the devices used, “all stakeholders” must nevertheless adhere to certain rules of the game. These rules are defined in the model protocols, which apply to the individual layers or are used...
