Welcome to Lecture 94 of the Data Communication course (CS601). In this session, we explore the "Data Link Layer" in data communication networks. This lecture will be presented in Urdu and Hindi to cater to a broader audience.

The Data Link Layer is a crucial layer in the OSI model that ensures reliable data transfer between adjacent network nodes. Join us as we discuss the functions of the Data Link Layer, including framing, error detection and correction, flow control, and media access control. We'll also explore different protocols used at this layer and their realworld applications.

This lecture is part of the CS601 course, designed to provide a comprehensive understanding of data communication principles and technologies.
