PowerCert Animated Videos is a great YouTube channel that publishes clear and concise explanations of big concepts in computer hardware and networking. Over the last couple of years I regularly used the videos in EDpuzzle to create short introductory assignments for my students.

Default Gateway Explained is the latest video published by PowerCert Animated Videos. The video does a great job of explaining to students why a default gateway is a necessary network component if they want to connect computers to the Internet.

On a related note, here’s the PowerCert video about DHCP and here’s my demonstration of how to create Edpuzzle activities.
