The 7 layers of the OSI model. This image illustrates the seven layers of the OSI model. Below, we’ll briefly describe each layer, from bottom to top. 1. Physical. The lowest layer of the OSI model is concerned with data communication in the form of electrical, optic, or electromagnetic signals physically transmitting information between

Each layer performs a specific task. It provides services to an adjacent layer This is similar to the concept of a function in programming languages – function does a specific task 13. 2016-12-24 DDoS attacks target specific layers of a network connection; application layer attacks target layer 7 and protocol layer attacks target layers 3 and 4. Why does the OSI model matter? Although the modern Internet doesn’t strictly follow the OSI model (it more closely follows the simpler Internet protocol suite), the OSI model is still very useful for troubleshooting network problems.
