Welcome to my site, dedicated to the Seven layers of the OSI model.


This web page is a tutorial about the OSI Seven-Layers model. In this presentation, I will take you through the detail in every layer, and how they work. Below is the order of layers. I will present them to you starting with the physical layer all the way to the Application layer. Lastly, I will present a table that will compare TCP/IP, with OSI, and Encapsulations (PDUs)

 

The Seven layers are as follows:
 
7- Application
6- Presentation
5- Session
4- Transport
3- Network
2- Data link
1- Physical
