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.

Excelente curso me gusto mucho la parte practica final, hubiera sido bueno agregar practicas de ser posibles por ejemplo en la parte donde se muestran los ataques y se van viendo / Excellent course I really liked the final practical part, it would have been good to add practices if possible, for example in the part where the attacks are shown and they are seen

The lectures were fast; good thing the videos could be paused. A lot of terminologies were given to you without any prior context and made it confusing sometimes. All in all, at the ending (Wireshark Module), I appreciated what I've learned and actually saw what the course taught me even at a small dose.

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 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.

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.

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!

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.

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 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.

It's much more interesting when a teacher adds something from himself and not just reads text. But if tou want to know a basics this cource if quite good.

Very interesting course. Sometimes, it moves to quickly for a beginner and some concepts could be explained through better analogies.
