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.

I love this course

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

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.

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

sir classes were very nice and easy to understand

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 .

Well organized and simply presented. Excellent for those wanting a quick way to learn about TCP/IP.

This course is a very comprehensive, intensive and precise introductory networking course. The course materials are well designed to the extent that every screen worth memorize and every sentence of professor's lecture google for further information. I have never come across a course as precise but well-structured as this.

A very good course to attend to know about the fundamentals of computer networks.

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.

Acquired a lot of entry knowledge about internet protocol and its application on cyber security. Thank you Professor!

Great course for beginners who want to jump in to the world of networking...

I really enjoyed taking the class, was a lot of information about TC/IP protocol. Very well explained by the professor, well organized, details, and assignment were about the topic of the course. I Highly recommend this course for a beginner into the IT major. Good luck for everyone taking this class

Great introduction to TCP/IP. It gives you an idea how it works.

Excellent and well presented course

Excellent course. The instructor did a very good job of explaining the things that I've always heard about in a way that I could understand them.

This course is just the cornerstone towards networking advanced concepts . All lectures are simplified to be understood ,Hence i enjoyed the course through having essentials concepts .

its interesting
