22. Introduction to Data Link Layer | Functions of DLL | Computer Networks for GATE & UGC NET

Master the Data Link Layer (DLL) in this comprehensive guide! We explore Layer 2 of the OSI Model, focusing on its critical role in node-to-node (Hop-to-Hop) delivery. This video is designed for CS/IT students and aspirants of competitive exams like GATE and UGC NET. What we cover in this video: Framing: How bits are grouped into manageable frames. Flow Control: Preventing the sender from overwhelming the receiver. Error Control: Detection and correction mechanisms (CRC, Checksum). Access Control: How multiple devices share a single link (MAC). Physical Addressing: Understanding MAC Addresses vs. IP Addresses. Hop-to-Hop Delivery: Why Layer 2 is different from Layer 3.
