So much of all Internet packets, whether they are in corporate, home, datacenter, or even service provider networks are carried by the Ethernet protocol. Ethernet is a Layer 1 and Layer 2 protocol specified by the IEEE 802.3 working group.
This course is an introduction to Ethernet principles and concepts. From understanding the structure of Ethernet Frames, to understanding how Ethernet behaves (including protocols like ARP and Spanning Tree), this course provides a solid understanding of Ethernet fundamentals.
