OSI MODEL BREAKDOWN - PART 2: DATA LINK LAYER

The Data Link Layer is the second layer of the OSI Model and plays a critical role in reliable data transfer within a local network. This video explains how the Data Link Layer organizes raw bits from the Physical Layer into structured frames, manages errors, controls data flow, and uses MAC addresses to deliver data to the correct device. What You’ll Learn: What the Data Link Layer is and how it works The difference between the LLC and MAC sublayers Key functions like framing, error detection, flow control, and MAC addressing How devices share a network medium using protocols like Ethernet and Wi-Fi Real-world examples that make the concepts easier to understand This is the second video in our OSI Model Breakdown Series—designed for students, IT professionals, and tech enthusiasts who want clear and accessible networking education.
