PowerCert Animated Videos use clear and concise descriptions of huge concepts in hardware and networking. I described them fairly often when I was teaching an intro to networking course last year..

As the title states, the video discusses what a MAC address is, how its composed, where to discover it, and its role in networking. The video also does a great task of discussing the key difference in between MAC addresses and IP addresses.

Applications for Education.
Most readers of this blog will never ever require to know what MAC address is or how it fits into the networking process. Nevertheless, it is nice to know and can helpful to know how to find it if your IT administrator ever asks for it.

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