Course is great. But after completion, it ask for money to provide completion certificate. I just finished but cannot afford to pay for certificate. I hate the way Course designer traps student. If it is free, then why are you asking money to provide completed certificate ?

Come introduzione và benissimo. Soprattutto la parte iniziale spiega molto bene lo schema generale delle comunicazioni.

As introduction is pretty good. Especially the first part explain in a clean and very good way the broad picture of the communications.

The best course I have ever found on TCP/IP. It's really interesting and one of the best courses on Coursera. I recommend this course who wants to have at least a minimal knowledge on Computer Networking. Thanks Prof. Moon to let us know all these.

introduction to tcp/ip course was really the awesome for beginners. and the prof.mr. jong moon chung was really good at explaining every concepts short and neat i really enjoyed his classes thank you prof.mr.moon thank you very much

Really good course and covers most of the topics related to TCP/IP. However, an improvement would have been explaining the tracert functions on how to set up the syntax for a command that requires the use of those functions.

Very good introduction to TCP/IP.

Theory is complemented by a practical example using Wireshark at the end of the lecture which is really nice. I would recommend this course for anyone with no or little knowledge of TCP/IP.

Supper clear especially chapter 1 subnet and routing table parts! It would be better if you can combine the IP4,6 header with wireshark lab together. And the rest of the chapters lack depth but are good for starters.

I didn't finish the course on time for various reasons so I missed the deadline for the final assessment but overall my initial goal was achieved: to gain a solid introductory knowledge into TCP\IP i can build upon.

It was a great learning experience, instructor is very interactive and i was able to understand all the topics efficiently. Best course for those who is interesting and want to upgrade their skills in networking.

I am already learned about networking but this course update my skills some Topic is very exciting and new for me like Networking Security & breaches and Wireshark projects.finally i enjoy and learn a lot.

This course gave me an overall overview of internet protocols, how the data packets are being transferred between the systems, a brief view of cyber attacks, and an overview of the usage of Wire shark.

It is a good course for beginners to get to know how behind the scene modern day internet works. The course also contains topics related to cyber security threats and how we can minimize those attacks.

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.

The course is very informative. The information that I learned from this course is new to me and it is also basic if you want to become a more knowledgeable person in this technological world

It was so interesting and helpful course. I enjoyed with this course. I got a lot of knowledge about Networking,TCP/IP model, Cyber Attacks and Protecting,Wireshark and etc.

Thank You

Content was delivered in a easily understandable format. Covered topics clearly, building a good foundation on the subject matter. I really enjoyed the learning process.

The content is helpful. The instructor teaches clear. However, the practice with Wireshark instructions (Week 5) is outdated and can not be replicated in MacOS version.

I took the class to learn something new, and I'm glad I did! I loved the professors way of simplifying the key concepts of every lesson. Thank you for the opportunity!

It is useful for beginners who want to pursue their career in networking field. Course is much better than any other university which had in its curriculum in India

as a begineer it was an very interesting course, as i came to know about lot of new terms like,

(phishing,wireshark,whaling,dns and lot of more new tcp and ip terms)

It was really helpful for our future endeavors as well as helped me gain confidence in particular fields of networking like TCP, Subnettin, UDP, IP and many other

This course was good and helpful. It was a great reminder about Networking, TCP/IP model, Cyber Attacks and Protecting, Wireshark and etc. It was also well taught

The videos are clear and concise, which shows that the professor values your time. The quizzes are challenging, and require you to pay attention in the lectures.

Clear and unambiguous presentation;

course material is structured nicely (lectures build on topics from previous lectures);

explanations are clear and make sense;

It was a great introductory course to network systems.Explained numerous concepts in the first 4 weeks and the final week was application based on the concepts.
