what an amazing course, so much information and yet so easy to understand, would recommend going over a few of the videos and supplemental reading a few times, take the time needed, it'll be worth it.

Apply yourself to these terms and concepts and you will gain knowledge that is presented in a very understandable way. Watch and rewatch the course videos and I promise it will all start making sense!

This course was amazing learned so much that I require one day to digest all that before I move on to next. I really loved the quiz and interactive question. This implementation of the quiz was super interactive something like what college tries to do active learning program but fails even in offline mode. Thank you, Coursera for providing such an amazing course to me. You are really helping me grow.

The Course was absolutely great. I have learned so much about Networking, Troubleshooting the Network, Cloud Computing, DNS, IPv4 and IPv6 to name a few. I have done some work in computers but not to this extent and the course has educated me to another level. It's now up to me to go further and explore more if I want to advance my career in computing. I can't wait to see what's next in this program.

The main presenter was very good at presenting all the information in a quick manner that still allowed for learning.

There are a few things I wish would have been changed but technically nothing that had to have changed to understand networking

I do wish they would have talked about the breaking apart of the telephone companies since they talked about them but that would be more fun then necessary

He was simply amazing, I meant the course instructor: Mr Victor. Definitely, one needs to go through the videos again for better appreciation, but we could still use a little more explanations on Traceroute, how Non-routable addresses can use a single public IP, Dns zones(sub domains), and subnetting. Also, I was hoping to learn cat6cabling (like construct it myself) in the physical layer lesson.

This might be one of the best and most comprehensive course on Introduction to Networking. The Instructor's teaching style and methodology is great. After completing this course I went for a CCNA course and this course served as a foundation to understanding those complex concepts.

I would highly recommend this course to all the beginners looking for a path in IT and who don't know where to start.

I'm hoping this was the hardest part, The funny thing is I have never had to analyze a packet for troubleshooting, so this was extra hard, especially the write the path to another computer. I would think most people will quit here. Don't because you can make it in IT the most jobs I see available.

These courses are a great starter for CompTIA Certs. I hope Coursera and CompTIA connect together.

Though course is superb in a way It's covering all concepts in their entirety and well scheduled but I'd recommend it must be accompanied with hands on as If I have had worked in IT organisation to practice the concepts told herein and not forgetting them ever. Here, I'd like to recall that Google did every effort to make learner feel If he's experimenting concepts in real scenarios.

By far the most important course in the Google IT Support Professional Certificate. This course provides the fundamentals needed in order to understand Computer Networking. I learned how computers communicate with each other, the protocols that they use, layers of the infrastructure, the details of the Internet, and the future of networking. The curriculum was a rewarding challenge.

This course was so in-depth and so thorough that at first, it was very daunting! Working through it though, and understanding that Google and Coursera were only providing me this much information so I could be completely prepared for a new career at the end, made it easier to push through. I loved every single second of the challenges that came with learning a new skillset!

Just like the first course, this was one amazing experience. The course was challenging, well paced, well structured and well delivered. The instructors were knowledgeable, professional and motivating. This course really made me understand how everything is connected. Tons of information and many concepts to learn, but they sure made it an interesting and exciting journey.

This course is very intense, and will challenge every fiber of self! At times I wanted to quit, however the structure of the course encourages you to continue and not give up. There is so much to remember and plenty to learn I wonder how I will be able to make practical use. But I will keep going to achive the goal of completion. This program is excellent and challenging.

An excellent primer on computer networking, teaches the network stack, DNS, and DHCP--the core of what you'll need to know as an entry level tech worker. Coverage of the history of many of networking protocols used today and technologies previously used offer a conceptual and technical understanding of how computer networks allow computers to communicate with one another.

A great overview of computer networking. It provides a broad overview of all topics, setting the learner up for deep diving into topic(s) of their choice. The narrator speaks clearly and (in almost all cases) explains thing very well. I did find the need to listen to some videos multiple times in order to grasp the concepts. Overall, very happy with this experience.

I really loved this course. I am looking forward to work in google in my career. I want to thanks coursera for giving me this excellent opportunity to increase my skills. I would recommend others to take this course and get to know the crux of the networking. I would to like to thank google IT team for making this course simpler so that any one can understand Kudos.

Even with a varied and extensive background, this course will give you the tools that you need to build your IT networking foundational skills upon. I am happy to have some formal training to beef up the knowledge I have already obtained through the school of hard knocks. Looking forward to other coursework that Google and Coursera have created. Onward and upward!

A very well presented course, with very difficult elements here and there. I had to research quite a bit in order to fully understand many of the concepts of networking. But that is OK - really. It sort of prepares me for real life, where things change all the time. So not only did I learn a lot about Networking, I also learned how to update myself on the issue.

It give me lot's of information and more understanding of computer network. yess... it is true that you have to understood a little bit of networking for this course. Since it it will be difficult if you are absolutely new in networking. but after al they give us a chance to learn since it is a week long for a module to be learn..

Thank you for the course..

I learned so much about computer networking and realized how much work is going on in the background of establishing a connection with a network. I truly enjoyed learning all of this information and it was all very easy to learn, with a few challenges along the way--but education wouldn't be education if it wasn't challenging. Thank you for this opportunity.

Really Tough course to get through, but I can see how necessary it was in order to build a solid foundation of the protocols behind the processes of sending data from one computer to another located around the world. If you like solving problems and logic, you'll really appreciate the genius behind how the entire TCP/IP 5 Layer Interconnection model works.

I enjoyed this course and I learnt a ton! Victor Escobedo was a wonderful teacher and it never got boring (IMHO). The first course in this series, Technical Support Fundamentals, was pretty basic, but this one is much more technical and interesting and you actually learn many concepts that can be applied to your job or even to troubleshoot issues at home.

Very well put together. Though for someone that has been doing this for some time this is pretty straight forward. However for anyone without any tech background the concepts my need to be abstracted down to more understandable concepts. This could also help other learn some new analogies that can be used to explain computing concepts to our customers.

I learned so much about how the internet works. How important and complex the internet really is. There is so much that goes into one website being accessed. Through this amazing course, with combination of short videos, practice quizzes, and fantastic information I was able to gain an understanding of the Bits and Bytes of Computer Networking. :)

Certainly, the most comprehensive course for understanding computer networks. The explanation of concepts, the protocols and various technologies is adequate. Lots of things to learn in course. The course material is designed well to cover all concepts extensively. Above all, the way our instructor puts things to perspective is just unbelievable!

Had an excellent time taking this course and learned lots about the world of networking that I had never encountered before. At first I was apprehensive about taking this course, I believed that networking was too complicated and I wouldn't enjoy it but now I am actually considering studying networking further because I found it so interesting.

I understood the concepts as I maintained a small network for four years knowing nothing and figuring it out via experimentation and googling problems with answers I rarely understood, but I learned.

The alphabet soup I never learned. I still can't define more than a quarter of them and hope knowing the soup of acronyms will not hinder me......
