The Troubleshooter Objectives. OSI Model | Computer Network Training. YouTube Video The OSI Model is composed of seven OSI layers that make up the model. Each layer is important to understand for proper understanding of network concepts of data packet creation and control. The layers start with Physical layer and end with the Application layer.
The first, second, and third OSI layer are important to know concerning the network equipment implemented at these layers. For example a switch is a layer 2 device and a router is a layer 3 device, but a some routers can be both a layer 2 and 3 device. Physical Layer The Physical layer is where the data is either put onto the media or received off the media. Data Link Layer The Data Link layer is where framing of the data takes place.
