Very good class, not difficult, doesn't take long and doesn't require any background knowledge. I would recommend it to anyone wanting to learn more about how the Internet and their computers work.

Fantastic introductory course to the fundamentals in TCP/IP. Great course for those new to computer networks and would like to gain a high-level to intermediate overview of how the Internet works.

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!

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!

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!

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

I wish that this course was broken up into 2 or 3 separte courses, I felt to rushed and there is a TON of information that I wish to retain.
