course instructor just read through the slides and do not explain in details with easy language.

The lecturer just read from the slides, no added value.

Very little actual explanation happened, technical level jumped all over the place like it was just copied and pasted from other sources; often without much theme of why parts got included.

The sections on security were particularly bad - as well as being frequently incorrect (or at best, over simplified)

Awful course, filled with senseless acronyms and very little useful explanation of the concepts. The Wireshark practical part, while potentially interesting, was very confused and very hasty. Save your time, do some other course.

Professor just read notes from the slides and did absolutely ZERO explanation. I wasted so much time just looking up explanations on YouTube. Great notes below par teaching!

Meh

Very informative! Opened up a whole new world to me (Wireshark). I did not realize the complexity and order that is involved with moving data from one device to another. Truly facinating and the instructor was excellent! Made the whole complex operation of TCP/IP seem like an effortless symphony of 1's & 0's. I really want to know more after having taken this online course. The toughest thing I had was setting aside the time to learn. After I work on this for a while I'm sure a habit will form and things will get more effortless. So don't let yourself get distracted and learn away. Great Course!

I'm rebooting my career in IT after specializing in linguistics and working as a translator for 15 years. I've taken numerous courses about IT Support and I was beginning to think maybe I just wouldn't be able to understand networking. It turns out all I needed was a good teacher who knew what a learner would need to know to understand the subject completely. I will forever be in your debt, Prof. Jong-Moon Chung. I've written down everything you explained in this course and now I have a little notebook that I can always refer back to when I need it.

It was great experience for me to have this course because I have learned a lot as a professional network administrator thanks for your well organized and explained course. I am really proud of it because it's improved my knowledge of computer networking both academically and practically. I am also liked the professor's explanations the way he projected and how he architecture was amazing .

thanks once again Prof. Jong-Moon Chung.

Prof. Jong-Moon Chung gives a thorough explanation of the TCP/IP workings using examples and even delves into Cybersecurity. My favorite part is how the quizzes are laid out as a "pick the INCORRECT answer." To me, this gives the learner a quick refresher over the subject matter, while still testing their retention of the subject matter. I kinda wish more quizzes were like this.

This is an exceptionally thorough introductory course to TCP/IP. It's well thought out, presented, and documented. And it's absolutely free! Adding to this, the downloadable handouts and videos make it an excellent source of reference. So glad I found and took this course! Many kudos and thanks to the professor (and Coursera) for making it available!

This is the first course I completed in coursera, and I think it is an extremely good experience. As an introduction course, the professor successfully grabbing the key point and he explained things quite coherently. At least I am very fond of his teaching style. I hope each of you learning this course can gain a lot!

A great course that introduce a lot of knowledges and infomation about TCP/IP basically about computer networking. although, I have to say this course is just to introduct a lot of networking technologies and what they are but not really indepth. Overall, a great course to get an over view of computer networking

It was very interesting to know how the internet works and what are the protocols used, how the networks are secured by taking the preventive measures from the attackers. I recommend this course to the people who wants to have a basic knowledge on TCP/IP.

This is an informative course about computer network. Although it may not be enough for us to master TCP/IP, it did provoke my interest and inspired me a lot. Also, Prof. Jong-Moon Chung is truly knowledgeable!

The content of the course is concise and summarizes all the essential points. The instructor speaks good English, has a profound technology background, and explains the system well. Thanks very much.

it was very helpful , i understand and relize every thing i was asking about , it was a simple and a powerful way to teach , THE TEACHER was very very good , i wish him long life and good helth .

For a course that teaches the basic computer networking, I would say i'm impressed by the modules that this course has to offer. This course helped me to pursue my career on computer networks.

It was very interesting for me that the explanation are very good.

the material are explained very nice.

wish to have more advance level .

I will recommend it to my friends.

Many thanks to you.

Really clear explanation and visual guides to help you understand the various protocols. I really recommend this free lecture in helping you to build a fundamental understanding of TCP/IP

Easy to understand but I think It needs more detail

For example, the "TCP" in week 2 is too short for coverage TCP header functionality, week 5 is even shorter for wireshark

The way the professor explained was excellent and beginners need to focus more on gaining knowledge about TCP/IP, overall I learned a lot from this course.

I learnt a lot from the course "Introduction to TCP/IP". Many thanks to Prof. Jong-Moon Chung for his expertise and clear explanation for this topic.

It is very informative and useful course, thanks for Coursera for this opportunity ,special thanks for Yonsei University and the brilliant tutor .

I appreciate the insight into computer networks and the internet. The use of Wireshark helped me understand real-time internet packet interaction.
