Computer Networking: Data Link Layer

In this free online data link layer course, you are introduced to the world of computer networking particularly focusing on the data link layer. You will explore the two sub-layers of the data link layer, as well as the features of the Ethernet protocol and the flexibility that organizations get from using VLANs. Demonstrations, problems, examples, and assessment questions in this instructor-led video-based course, are designed to provide you with a comprehensive foundation, which will enable you to take serious steps into understanding this section of the protocol stack.

The data link layer protocols course begins by introducing you to the reasons why the data link layer is one of the predominant layers in the OSI TCP/IP protocol stack. Then the two sub-layers, which are the medium access control (MAC) layer and the logical link control (LLC) layer, are discussed to help you understand their uses in the network. You will explore the different ways of controlling access to a shared transmission medium and the collision detection process.

The data link protocols course includes topics on LLC services, LAN protocols, MAC frame format, Ethernet technologies, collision detection, error and flow control mechanisms, ARP operation, RARP packet format, VLAN tagging, and more. This data link protocols in computer networks course will be of interest to computer engineering students, networking and programming professionals, or those looking to enhance their career prospects in the computer networking industry.
