The majority of readers of this blog will never need to understand what MAC address is or how it fits into the networking process. It is good to know and can practical to know how to locate it if your IT administrator ever asks for it.

PowerCert Animated Videos use concise and clear explanations of huge principles in computer system hardware and networking. I described them relatively often when I was teaching an intro to networking course in 2015..

The newest PowerCert video is MAC Address Explained. As the title states, the video discusses what a MAC address is, how its composed, where to find it, and its function in networking. The video also does a fantastic job of describing the crucial difference between MAC addresses and IP addresses. A fast description of ARP (Address Resolution Protocol) ties the key ideas of the video together..

This video is one to bookmark and possibly utilize as a review resource or video-based lesson in a tool like Edpuzzle if you do teach networking.
