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 was best experience to complete this course from this application !!

the explanation wasnt clear, it was basically just like if was reading a dictionary. I almost learn nothing. Need to improve the way they explain thing and not just say the meaning of something, for example say DNS and say "DNS is this and this" and then continue with something else.

Nice introduction to TCP/IP

Covers the TCP/IP basics very clearly! I highly recommend it to anyone that wants to get a quick primer on the sub

Excellent course, went beyond what was taught in University!

It was really helpful for our future endeavors as well as helped me gain confidence in particular fields of networking like TCP, Subnettin, UDP, IP and many other

It is a very useful course. The second half of the course might be too tedious as it includes much details on the protocols formulation which does not concern with people who is not in communication technology major.

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

Comprehensive and informative course material. Really enjoyed the quizzes.

sir classes were very nice and easy to understand

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

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 .

Too basic and only windows based. The project using wireshark could have been used more to help understand the theory presented earlier.

Overall the content is decent and I learn a bit here and there. But I feel that it is still lacking slightly, but since it is a introduction I won't fault it for that. But overall I feel that is not much explanation and a lot of buzzword and assuming the audience already have knowledge to it.

Value addition

Awesome course, though the questions could have been better and the high level details on protocols and all could have been highlighted in a better manner. Non the less, its an awesome course.

more practice would be better
