The OSI model has seven different layers, which are divided into two groups. The following table lists all the layers with their names and numbers. Let’s understand each layer in detail. This tutorial is the second part of the article "Networking reference models explained in detail with exam...
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 Open Systems Interconnection (OSI) model describes seven layers that computer systems use to communicate over a network. The OSI model is divided into seven distinct layers, each with specific responsibilities, ranging from physical hardware connections to high-level application interactions. Each la...
The seven layers of the OSI model, in order from the lowest to the topmost, are the physical layer, data link layer, network layer, transport layer, session layer, presentation layer, and application layer. Let us learn about these layers of the OSI model and their functions in detail. Ph...
本文探讨 Windows 网络体系结构以及 Windows 网络驱动程序如何实现 OSI 模型的底层四层。 有关模型的所有七个层的一般信息,请参阅OSI 模型。 Microsoft Windows 操作系统使用基于 1978 年国际标准化组织 (ISO) 开发的七层网络模型的网络体系结构。 ISO 开放系统互连 (OSI) 参考模型将网络描述为“一系列协议...
OSI Model Explained What’s the OSI model? The Open Systems Interconnection (OSI) model is a framework that conceptualizes how computers within a network communicate. It splits this process into seven distinct layers, each one playing a specific role within the overall operation. ...
The OSI and TCP/IP models have similarities and differences. The main similarity is in their construction, as both use layers, although the OSI model consists of seven layers, while TCP/IP consists of just four layers. Another similarity is that the upper layer for each model is the applicat...

In order for human-readable information to be transferred over a network from one device to another, the data must travel down the seven layers of the OSI Model on the sending device and then travel up the seven layers on the receiving end. ...
This layer is similar to the OSI model’s L4. Layer 4 (Application): Also called the Process layer, this layer combines the OSI model’s L5, L6, and L7. How Network Layers Work As we walk through an example, keep in mind that the network layers models are not strictly linear. One...
