A really great course to get started with computer networks and networking. The lecturer Mr. Jong-Moon Chung   has really put a lot of efforts and made this course really interesting . I'll really recommend this course to my juniors who are getting started with computer networks.

The graphical representation is not great. It looks like the clip coming back from 20 years ago. Is the instructor CGI or real person I am not sure. The break down and the script of the lecture is very good. It is very usefu 'll to have nice foundation in networking career.

This a good introductory course on network protocols. It offers a starting point for a more in-depth study of the protocols.

It would have been good to have however more examples/details on how routing works in more complex network types such as subnets in LANs/WANs.

The course was interesting, it is a problem that I do not know English very well to take the questionnaires and there were also 2 videos that were not translated, I could not access the download test files to use wireshark, but I learned a lot thanks

The course is delivered by highly qualified instructor. It is a grate opportunity to have such kind of online course's for those who want to learn but have no access for good education especially who are living in poor counties like Africa.

Very good course for beginners to understand not just only TCP/IP, but to have an overall big picture about computer networking, and more specifically TCP/IP protocols, instructure is very knowledgable and explains thing very clearly

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.

The course is well paced and does provide good information about the basics. But this course could have covered some topics like TCP, UDP, IPv4 to some additonal extent as well which would have provided better clarity to learners.

Ideal for anyone who wants to review concepts quickly and thoroughly. The course is well grounded only for beginners. So if you're a beginner perplexed where to start,this is place to try. All the best to future learners !

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.

La verdad es un curso bastante interesante para hacer en estos tiempos de pandemia, aprende muchas terminologias y cosas que no tenia idea que existian y me dio una mayor idea de la funcionalidad de una red

Very nice presentation material, concise and thorough. Lecturer was pretty good at giving information and keeping everything to the point. It is a nice introduction for very high level information on TCP/IP

This is really good to start as a beginner. Some points require a more detailed instruction, such as starting Wireshark and getting IP address to proceed the course, yet I strongly recommend this course!

It is a very good course. For beginners it would be very helpful to understand the TCP/IP and many more through this course. You will also learn about cybersecurity in this course. Thank you.

For an intro class there were a lot of new terms and concepts for me. It was super fast and concise, I had to rewind a lot but the material was very helpful and the instructor was great.

This course needs to be updated, especially the last lesson which heavily depends on Wireshark. The examples use an old version. It also needs to have alternative instructions for Macs.

good for beginners to get basic knowledge. First part explaining ip addresses in details is great. Baidu and gdrive links didn't work, but I played with wireshark anyway. thank you!

a lot to cover, very fast and very technical. Maybe some other sites used for reference examples would have helped. Great course content. Also, TLSv1.3 is now being used.

This course was really cool, It could have been even more interesting if each chapter were combined with some practice using Wireshark. Thanks a lot for this free course.

Buen curso introductorio, es bastante bueno sin ambaego hay algunaas cosas como la traduccion paraque sea mas accesible para todo el que tenga un interessobre el tema

The last lesson should be more explicit in areas of downloading from the drives and at least more practical slides or simulation videos on real time with wireshark

I thought i was going to learn about the local connection and how to administrate them, althought i learned about the singular parts of the internet connections.

it is such a nice course available free of cost where i learned about tcp-ip,here we can get so much knowledge about TCP-IP in short time period....Thank-You!!!

It was really educational and fairly easy to follow. I was hoping for a certificate however when you pass, you do have to pay for it. Very good course though!

Got the know the basics of IP address, various type of cyber attacks and ways to defend them. Interesting part was analysis of network packets via wireshark.
