Course Description

This course introduces the Link Layer (Data Link Layer), the second layer of the OSI model, and its essential services in computer networks. Students will learn how data is framed, addressed, transmitted, and protected from errors during communication between directly connected devices. The course covers framing, MAC addressing, error detection and correction, flow control, access control, and link-layer protocols such as Ethernet and Wi-Fi. Through practical examples and network scenarios, learners will gain a strong understanding of how reliable node-to-node communication is achieved

Course Outcomes

By the end of this course, learners will be able to:

Explain the role of the Data Link Layer in the OSI model.
Describe the key services provided by the Link Layer.
Understand framing techniques and frame structure.
Identify and use MAC addresses in network communication.
Explain error detection methods such as CRC and checksums.
Understand flow control mechanisms for reliable data transfer.
Describe media access control techniques used in shared networks.
Compare wired (Ethernet) and wireless (Wi-Fi) link-layer technologies.
Analyze how link-layer protocols support efficient communication.
Apply link-layer concepts to troubleshoot basic network issues.
