PowerCert Animated Videos offer concise and clear explanations of big principles in hardware and networking. I described them relatively often when I was teaching an introduction to networking course last year..

The most recent PowerCert video is MAC Address Explained. As the title states, the video explains what a MAC address is, how its composed, where to find it, and its function in networking. The video likewise does an excellent job of discussing the key difference between MAC addresses and IP addresses. Lastly, a quick description of ARP (Address Resolution Protocol) ties the crucial ideas of the video together..

This video is one to bookmark and perhaps use as an evaluation resource or video-based lesson in a tool like Edpuzzle if you do teach networking.

Applications for Education.
Many readers of this blog site will never require to know what MAC address is or how it suits the networking process. However, it is good to understand and can valuable to understand how to locate it if your IT administrator ever asks for it.
