Awesome course that sheded a light on communication technology. The lectures are quite involving but given at straightforward language avoiding use of hard technical terms. I would like to convey my heartfelt thanks to prof. Jong-Moon Chung for the job he has done. Highly recommend the course to all newbies at the telecommunication area.

It could be more specific and detailed. His accent was really good though.

This course is just a bunch of random networking videos, without any structure. Also there were couple of mistakes in the videos of first week and Last weeks assignment was a joke.

Supper clear especially chapter 1 subnet and routing table parts! It would be better if you can combine the IP4,6 header with wireshark lab together. And the rest of the chapters lack depth but are good for starters.
