This week, we continue our journey down the protocol stack and arrive at the Data Link Layer . We will explore how data is exchanged between devices connected through wired or wireless links, or via non-routing devices within the same subnet. Topics include framing, error detection, multiple access protocols, and the practical challenges of communication in local-area networks.
