World of Computer Networking Your CCNA start - Working of Network Switches

The video tutorial explains how network switches operate on the physical and data link layers of the OSI model, focusing on their role in transferring frames between devices. It covers the concept of MAC addresses, their structure, and how they are used in MAC address tables to facilitate communication. The tutorial details the process of frame forwarding, including how switches learn and store MAC addresses to efficiently direct data. Finally, it introduces the structure of Ethernet frames, setting the stage for further exploration in the next lecture.

Explain how a switch updates its MAC address table when a new device is connected.

Describe the process a switch follows when forwarding a frame to its destination.

What does a switch do with frames that have incorrect frame check sequences?
