PowerCert Animated Videos offer concise and clear descriptions of big ideas in computer system hardware and networking. I referred to them fairly frequently when I was teaching an intro 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 role in networking. The video also does a terrific job of discussing the crucial difference in between MAC addresses and IP addresses. Lastly, a fast description of ARP (Address Resolution Protocol) ties the key concepts of the video together..

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

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