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.

The course was experimental in understanding the theoretical aspect how data are transferred from the source to the destination. The Architecture of IPv4 ,IPv6 ,maximum size allocation which helps the user to understand the dynamic allocation at the backend.

The course also had a detailed session on the various Cyberattacks and how the attackers/hackers try to manipulate the information from the server.People fall prey into their trap by unknowingly clicking on these fake website links which connects to the Hackers IP Address and fetch information of the user. This course will give a thorough knowledge and help the client to use the Internet in a more secured manner

Muy interesante el curso en general aunque en algún apartado hay excesivos conceptos que es difícil asimilar o ver su carácter práctico, como en el tema por ejemplo de protocolos. A pesar de que tengo muy pocos conocimientos técnicos, he podido seguir la formación correctamente aunque con alguna dificultad en algún punto. El curso se ha ajustado 100 € a lo que esperaba de él.

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.
