It is a good course for beginners to get to know how behind the scene modern day internet works. The course also contains topics related to cyber security threats and how we can minimize those attacks.

I love this course

Very introductory and not deep at all.

it is very helpful for me a newer of tcp/ip

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.

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.

Good knowledge i found on internet

The course was good and covered topics I expected it to cover. It would have been great if the quizzes were after an immediate module rather than being at the end. Over all a well designed course topic wise and provided good insight.

Being very new to networking, new concepts were, in general, slowly and logically introduced, with tangible, real world examples/metaphors for abstract concepts. My only criticism is that a lot of information is introduced in the first week's lecture, without reassurance that in-depth, previous knowledge of these concepts is not necessary, so I spent a lot of time researching what would eventually be covered anyway.

Ce cours a ete vraiment enrichissant pour moi, merci a Yonsei University, ainsi qu'a la HCR pour l'opportunite .
