This course is just the cornerstone towards networking advanced concepts . All lectures are simplified to be understood ,Hence i enjoyed the course through having essentials concepts .

Awesome course that sheded a light on communication technology. The lectures are quite involving but given at straightforward language avoiding use of hard technical terms. I would like to convey my heartfelt thanks to prof. Jong-Moon Chung for the job he has done. Highly recommend the course to all newbies at the telecommunication area.

Amazing course and for sure the easy and understandable explanation. I highly recommend everyone to take this course if you wanna very basic of TCP/IP, OSI module and various cybersecurity terms.

It could be more specific and detailed. His accent was really good though.

I had a basic understanding of the TCP/IP, but this intro course was a little more in-depth than expected! It definitely gave me a better foundation to build on. Module 5 could use some improvement. The tutorial on downloading Wireshark was fine, but the follow-on lessons on Wireshark employment left quite a bit to be desired. Overall, I recommend this course. The professor seemed knowledgeable and easily related the material.

Being very new to networking, new concepts were, in general, slowly and logically introduced, with tangible, real world examples/metaphors for abstract concepts. My only criticism is that a lot of information is introduced in the first week's lecture, without reassurance that in-depth, previous knowledge of these concepts is not necessary, so I spent a lot of time researching what would eventually be covered anyway.

This is a very good course for beginners and intermediate computer users. It introduces the basics of TCP/IP and many such protocols in a clear and crisp format. The trainer Jong Moon Chung was excellent and his accent, presentation deserves praise. I recommend this course for beginners and experienced personnel alike. Thanks Coursera for offering this Free of charge.

This course is just a bunch of random networking videos, without any structure. Also there were couple of mistakes in the videos of first week and Last weeks assignment was a joke.

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.

Awesome course, though the questions could have been better and the high level details on protocols and all could have been highlighted in a better manner. Non the less, its an awesome course.

I really enjoyed taking the class, was a lot of information about TC/IP protocol. Very well explained by the professor, well organized, details, and assignment were about the topic of the course. I Highly recommend this course for a beginner into the IT major. Good luck for everyone taking this class

Explained the basics of TCP/IP in a well structured and understandable manner. Recommend the course to anyone looking how a simple connection to internet (www.google.com for example) or a ssh to hostname / ip address works and the what the gateway, router, subnet means. Thank you Professor.

Very interesting course. It was somewhat compact and many topics were introduced. Although I finished the modules, I am planning to revisit lectures again. It gave me a great foundation while introducing me to many new concepts such as hashing Vs. encryption & Wireshark project

This course is a very comprehensive, intensive and precise introductory networking course. The course materials are well designed to the extent that every screen worth memorize and every sentence of professor's lecture google for further information. I have never come across a course as precise but well-structured as this.

its a great course for those who want to learn about networks. It's a bit fast paced and suggest to read on the reference provided at the conclusion of each module to understand further the module lecture especially to those who have no or very limited knowledge about networks.

its an amazing course, now i have a good understanding of what tcp/ip is and how data is recieved and transmitted also internet attacks and how to prevent them. thank you to coursera younsie university and professor jon-moon chung for making this course availabe

Great introductory course in TCP/IP networking, also included a lot of interesting extra reading through the recommendations for each lesson. So after every lesson you could learn more and dig deeper. Wireshark lesson was especially interesting and fun.

Before this course, I had many doubts of my understanding about how the transmission is happening from one point to another.

This course gives high level and low level definitions about protocols and networking for beginners.

I high recommend this course.

It is a very interesting and useful course and I will nominate it for my friends so that they can benefit from it and the lectures are also a simple and easy explanation and the scientific material is excellent and I wish more courses in the CCNP

A good introduction for those of us who are new to the world of internet protocols. Very informative lectures with clear explanations that don't go too deep into detail as to lose you. Just enough to whet the appetite for more...thank you!

the course is very interesting and the way of teaching the subject more interesting

and easy i understand this subject now better than when i studied it before back in collage

and the way of explaining with videos if very good

Curso bien estructurado, inicias con conceptos básicos de tu propia computadora, estudias los diferentes prototipos de comunicación y finalmente analizas los paquetes recibidos de un servidor en un ejercicio practico.

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.

For the price I expected much more information.

The instructor was superb. I took this course as a refresher for an upcoming job interview related to cybersecurity and it helped me a lot to understand the foundations of networking concepts in a clear and concise way. This course probably left me a lot more knowledge and understanding of the topic than my paid college courses.
