[@brianm75]

Thank you so much for posting videos of your class. I'm current taking Cisco classes through the local community college and you teach the course so much better than my current instructor. This video helped bring everything that I have been reading about together in a way that I can understand it now. Thank you again.

This is a very well done lecture. I am currently in college studying networking and this video helped me tremendously in understanding the Data Link Layer of the OSI model. Thank you.

Very well explained

Hello Nicholas, Very good explanation again, marvelous. I wanted to add that at minute 42 you were saying that switches still use CSMA /CD. But according to Cisco documentations this is not longer supported since each ethernet port or collision domain is isolated. However it has to be implemented in HALF duplex.
