This course was amazing and helped me understand so much more about networking, things I never thought I would know or understand. Very fulfilling and I can't wait to use this knowledge going forward.

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.

Very informative course. To be honest, I struggled keeping up with the course because so much information was thrown at once. But just keep up with it. I came from a background with pretty much no IT experience. I'm learning a lot but I would say to not expect that you will get through the course in days or maybe even a few weeks if you don't have much of a background in the field. But so far I am loving the courses.

ver y good but i was missing analogies to more grapeable things in order to understand the concepts and technologies better and maybe some simple examples that follow us throughout certain themes. Also the mid video questions from the first course arent here anymore which made me a bit sad. overall a great course but it could be improved in some aspects i think. still great work and glad it exists :) Great work

Great section! Someone really needs to proofread both the script below the video and the closed-captioning though - throughout the bulk of these presentations.

Also, the final tests are demonstrably more difficult than the in-between quizzes. I do not mind the difficulty level (that is how one learns), but I feel like I am not learning anything through the quizzes which makes me woefully unprepared for the final.

Lots of good information in the course, but there were a number of assignments that were incredibly frustrating from a technical standpoint. Taking 3 hours to do a 20 minute assignment due to tech issues is an incredibly frustrating experience. For any future learner, make sure you set aside time for the Qwiklabs and the small tertiary assignments (usually the practical assignments after the 15 question quiz).

Victor did such a great job with all the puns. lol This is a bit more challenging than the fundamental course but everything taught in here are all valuable knowledge of how the Internet works today & how Computer Networking works. I'm giving this 4 Stars because there was a bug with one of the questions for Ipv6 Compression & it failed me when I submit it. Thank you Victor, for being an amazing instructor.

It was really a great learning experience. Teacher is very articulate. Nice slides and to the point info. Only thing was hard week 2 Quiz, about network connections, I did the assignment without understanding it by trial and error. I think, teacher should make an extra video to take thru few scenarios, how to calculate the network addresses for the routes for data transmission. Thank you Coursera and Google.

Maybe a more detailed, physical construction of the five-layer network model would help more. Maybe something like an assignment that isn't weighted heavily instead of a multiple choice quiz. Something like a puzzle if that makes sense. Connect each layer in order, construct the encapsulation by hand, etc. Overall great course. May have to refer back to it but I know it has most of everything I need to know.

Great course. I wish there were more visuals to accompany the video lessons. I had to refer to a lot of outside sources, YouTube videos, to fill in some of the gaps I had in understanding the lesson material. Overall, I learned a ton from this course and far more than I could have learned anywhere else, I think. So I'm grateful I had the chance to complete this course. I'm looking forward to the next course.

Very good course to take to help you understand computer networking. It is a great place to start. I would give it 5, but there wasn't enough hands-on opportunities to use the skils talked about in the course. I would like to see more labs to use the networking diagnostic tools or have some troubleshooting labs setup and test the knowledge that was gained from the course, not just multiple question quizes.

There were very little examples of real life scenarios. Theoretically everything makes sense. But, I couldn't connect to a real life situation. Maybe it's just me.

For example : When are we going to use IPv6 compression, and why can we use a calculator that does it for us.

(I spent 3o mins on the IPv6, because i couldn't compress one, and it kept reapeating)

Overall, I definetely now know more than before :)

There were many great subjects and lectures. My only complaint involved a few areas that could have benefitted more from hands on practice or examples. Areas such as subnetting or IPv6 compression required external videos and material to get a handle on it. Maybe provide this at the end of sections for practice or inbetween where the supplemental material is. Otherwise thank you for the continued learning

Very good and informative course. I feel like some of Week 2 and Week 3 could use some refinement to improve the course experience. Very heavy in information, terms, and concepts but not a lot of reinforcement activities like we saw in the Technical Support Fundamentals classes. Video pauses that pop up with quick question quizzes can slow the monotony of the course and ensure key concepts are reinforced.

I really enjoyed this particular course out of the 3 I have done so far. I look forward to the other 2 not yet started in hopes that they'll be just as this one was. The only issue I had was some stuttering with one of the graded quizzes in that, it showed everything green when I used "check", however when I hit submit, it said "0%" and I had to retake it after refreshing the browser and clearing cache.

I contains a lot of technical information that can be difficult to process and assimilate in one go; depending on the person, the videos might need to be watched more than one time. It would be nice if they had more graphics or images relating to what is being said, as well as more interactive exercises and maybe more examples related to the real world and daily life that most users might encounter.

A very good introduction to networking. Only reason one star is taken away is because of the low quality of some of the exercises. Often they were unclear as to what you are supposed to do, the grading system was buggy or inconsistent, and there is no participation by the mentors or any Google staff at all. Otherwise the depth and detail of the course is just right for the level and role intended.

Great course, but in some cases there were drawbacks, mostly in the Graded Assessments, where I couldn't just correct one error like missclick for instance, but I just had to reset the whole thing. That's very frustrating, especially when you are in the last task and boom missclick go back and do the whole thing once again. Also the last task: deleting zeros. God damn it was like Where's Waldo...

I really enjoyed this course. It was challenging, but not too difficult. The best part is that I can work on my own schedule. The only reason it's 4 instead of 5 stars is because I didn't receive any notification on the due date of the final module's graded assignment, and as a result, I was a day late on turning it in. Since this was the only time it happened, I suspect it was simply a glitch.

The IPv6 compression quiz needs to be checked due to the number of times that I took it and answered all questions correctly but after submitting the quiz, I would receive a grade of 0. This resulted in me being late on an assignment. This issue is also the subject of many threads in the forum, some over a month long.

I very much enjoyed the course, but often I felt lost in all the complicated material. The subnetting section was extremely hard for me to grasp and had to find other material outside of the course (YouTube) to help me better understand. I think for more complicated sections/modules it would be helpful to maybe explain or give more time to go over concepts. I felt it was a bit rushed at times.

It's okay for a non-technically minded person. I think this part could use much more video of how things work as the speaker is explaining the concepts. Many people taking this course are not technically minded, which means they need it broken down into layman's terms or in a way they can relate to it. I think it would be better with more step by step video "art" while the speaker is taking.

This course makes the process of learning basic IT concepts very approachable . It's broken into small sections, which makes studying very simple to obsorb at a resonable pace. On week's with topics that I grasped more quickly, I was able to move ahead confidently or go more deliberately on topics that I did not understand so easily. Entertaining even on topics that get a little "hairy".

This course has very valuable information and the instructors seem very knowledgeable, however, I've experienced issues with one of the quizzes and although I reached out in the appropriate manner I received no response. There is no one to speak with if there are problems and I don't feel that is good teaching ethic. As a whole I am learning a lot and plan on continuing with the program.

I would have given it a 5 star except for the fact that the IPv6 question on the quiz was bugged and additionally the networking quiz was difficult and the explanations weren't completely clear. Specifically, that you can only abbreviate with the double colon once when abbreviating an Ipv6 address. However, I did enjoy the course , it was very informative and I feel that I learned a lot.

Really enjoyed the course, was a bit difficult for me but that shows that I needed to learn, thats what school is about anyway. At first I didnt understand how Im supposed to learn anything online. As I did the assignments and I did fail some of them, reviewing my assignments was the way I learned. I got to try them again and I realised that I then knew the correct answers.

So, this course is very challenging and can improve my understanding of the networking concept(which I feel I'm quite weak in this area).

Just one thing that you must score perfectly in a quiz about IPv6, if not your grade would 0% no matter how much you try. I've been through that then I realized, so I hope this would be a guiding light for us all.

Great, and thanks for all the Tutor!
