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.

Could use a lot more helpful ways of understanding subnet masks and how the CIDR notation is worked out. Other than that, very helpful ways of learning ie. through video learning and supplemental reading as well as readings after videos to go deeper into the topics discussed. Quizzes were helpful in understanding the general concepts, however I do believe the quizzes could be more interactive as some of them are. With more interactive learning, it becomes much easier to understand how these new topics can be applied because actively doing the things shows us how it would be working in networking or in whatever topic we are currently covering as opposed to multiple choice, where an educated guess can more times than not help arrive at the correct answers.

Very informative. I enjoyed seeing into all the different protocols in detail. Before now the different networking models felt very inconclusive and confusing. Now I can tell you where a device falls into that model, the function of every layer, and what protocols are in place to keep it operating. I finally learned the infrastructure of how networking is organized. Before this course I could have easily told you about a DNS address and IPv4, but I couldn't tell you much of how it worked or why. This course took my surface level knowledge, and explained not only how we use it, but why. This course does an excellent job of building a foundational understanding of how the internet works, and what the future of technology is doing to improve it.

I really want the routing game to be a practice tool in this course. Not just in the test. Also, I am sure anyone struggling with the IP test in the last part could use some practice on it also, but once I did a few it wasn't so bad. I still want to play the routing game that was in the second quiz and I can't find anything like it elsewhere.
I also don't like that some of the topics are skimmed over and quizzed in basics rather than more detail. Some of the physical and network link layers also blend together to me at this point sometimes, but I believe I have the basic understanding to pursue other certificates with this knowledge.
Overall, this was a very useful course that gave a better understanding of networking to me.

This course was very good, yet I feel it could be just a "touch" better.
What I mean is I personally would have liked a "bit" more lab work. The course was instructed very well and the few 1 question quiz labs you take throughout the course were great. I personally would like a few more hands on labs added to the course - maybe in a 3 step approach - Beginning, Middle, End - I feel it would keep you involved more visually and assist in just showing the common real life steps you will physically have to take when resolving networking issues as an IT Professional - Other then that, the course was AMAZING in the knowledge you gain and understanding of the true genius behind networking and the internet as a whole

I understand lectures are an important part of any learning. But I would like to see more lab type listens to enforce the knowledge we are learning. For instance, I listened to the videos concerning IPv6, and how to shorten them. But I did not truly understand it until I took the test, actually using the knowledge to shorten the addresses.
There are many items, such as the different packets and protocols, that could be better explained using some type of lab.
But I have increased my knowledge. I have a deeper understanding of networking now. I just feel that there are some areas that I know, but don't truly understand. A lab portion could make a difference in that.

A very nice, digestible introduction to a 5-layer networking model!
Drills all the way down to the packet and media layer where bits travel as electrical signals, explaining switching, routing, DNS servers and other core networking infrastructure. Google presents things in a nice fashion, with good diagrams, analogies and explanation throughout. This course isn't a replacement for CCNA or whatever other massively deep networking certifications exist out there, but it'll give you a great foundation to understand and perhaps entice you to learn even more!
So far, my favourite course from the Google IT Support Certificate Specialisation here (I'm on the final one now).

This course I rated a little bit less than the previous course because I feel like a lot of this information is very helpful, although I feel there should be more in this section on just making sure the users understand fully what is being taught and introduced and how its used with maybe more VR machines like used in the previous course. I loved that I learned a bunch of valuable information I just feel like the 5 layer network really does stump some people. I suggest possibly in the future doing a drag and drop diagram for the 5 layer network as well to have a better understanding of it. :D This course was very information heavy but awesome to learn!! :D

To me this was a hard course to understand. Some of the Modules and assignments should have had various examples and practice questions before the test/quizzes. One thing I did not like is there was very little feedback why we are wrong and how to approach the problem. I'm lucky that I am studying for Network+ and my CCNA so this was not so bad. However I quit this course a few months back because the content was not enough in my opinion to pass some of the exams. I had to youtube and learn from many other sources to find the answer and even the instructor showed Youtube videos instead of finding the answer from the provided content by google.

The course tests are not graded correctly, specifically, IPv6 address compression. Google grades differently to what they teach. And, they're wrong with the grades on IPv6 compression.
I figured out what Google did wrong with this IPv6 compression quiz. In the grading, they implemented rule 2 incorrectly. The rule states you can replace 2 or more hextets of all zeros with a double colon. Google replaces just one hextet with a double colon.
5d66:5ec9:46:0:2576:4f:7159:639 (correct, but Google calls it wrong)
5d66:5ec9:46::2576:4f:7159:639 (incorrect, but Google calls it correct)

This course was very complicated and it's some very good material to learn. I do think it needs to be broken down further and more interactive. Most of it was just talking and telling definitions which for something like this makes it hard. In the beginning when there was the router and switch comparison to sending mail and how you receive it was fantastic! If more is done for other concepts like this, maybe using sport terms or doing something for the mail delivery again but in more depth, then maybe more will get the hang of it. It took me forever to pass due to it's difficulty and my limited time but I finally did it.

It's a good course and learned enough information to get me by in a midocure conversation on this subject. Like every process of learning something new, it is a challenge and worth it. This could of just been me but the way the course is broken down is intense for someone who has no knoledge in this catergory. I had to put in extra hours looking up things and watching videos on other sites to understand what this couse was talking about in their short videos. In a nut shell they gave me a path to fallow and I liked the challenge, I just wish it was updated and had more resourses on the spot to help me understand.

Definitely a harder module than the first. Lots of new concepts. I would give it 5 starts but there were some breezy passages that warranted more explination, and maybe from a different present to make sure you got a diverse look at the topic. I'm looking specifically at subnetting, and the process of the three way handshake over networks. I had to go to external sources to bine up on these. There were some stinkers of questions in the quizes that had wording ambiguous or contrary to video content, but that is a given in even college coursework. Over all I learned a bunch and enjoyed the process. Onto the next.

This is really a step up, from module 1, however it is impossible to know and learn everything about networking. If people going on the will find that CompTIA or Cisco having a different approach to things, said this Google setting the baseline here, and people interested in this field should look for CompTIA Network + certificate, rather Cisco since it is vendor based and mostly you can see it as training for their own products than anything else, not every company has the money for the high end equipment. Therefore it is good to know the fundamental things disconnected from any specific branded soft/hardware.

There are a lot of wording errors in the class that i end up having to guess on the quizzes, tests, and projects. For instance in the class it states that you put "::" instead of having "consecutive groups of just zeros". Nothing about a single group of zero's. When it came to the project, there was a single group of a zeros and I was just talking out the leading zeros as per the first rule of shortening an IPv6 address, but after a few times of going back to the videos and making sure I am doing what they say, I try to just use the double colon and it worked. This only one instance, but they are all over.

I really recommend this program to any age group person. thanks to this program I am nowt so intimidated when I see ERRORS pop up on my screen and I now feel capable fixing or trying it on my own, and that's good coming from a person that would go on panic mode when turn on the computer and I could not get on. And things words like bandwidth would not registrar in my head what it meant and how that impacts your hole process to operate smoothly or how to access your command prompt and all the features that are in it. Anyways, this program is absolutely worth the time and effort you will put in to it.

This certificate was much more difficult for me. A lot of information to take in at once. The presentation format is the same as the other certificate I completed and do like the various ways the information is presented. I think with the information I need it to be with more examples and even broken done to more videos and slower. Some videos were 5 to 7 minutes long with lots of info. Even if I watched over and over again the information is presented in the same manner. I still enjoy what I am learning. I think it was this particular topic that was difficult for me to wrap my head around it.

The concepts introduced in this course are very complicated, particularly for those uninitiated in the technical aspects of the internet and computer networking. It was a very challenging course to understand, but very rewarding to complete. My one criticism would be that some of the lectures fell a bit flat on explaining these complex systems, and i usually resorted to accessing supplemental learning elsewhere in order to fill the gaps. Perhaps going forward instructors can implement the use of some graphics or even a dry-erase board to physically draw out and explain these complex ideas in detail.

The course itself is good, but if you do not have prior knowledge, I believe that it will be difficult to understand many of the concepts covered. It has a very extensive content, with many theoretical classes that explain each layer in detail. I believe that many of the negative evaluations of this course are due to the extensive applied theory. It is useful to know each concept in detail, but in daily professional support, a practical approach can be more useful.
At least in relation to the course I took at the university, this course in theory went beyond the content of an entire semester.

Very technical course and packed with tons of concept about networking. The reason for 4 stars because I felt that concepts are introduced quite rushly. Resulting overwhelming of information, and students might only hear about a concept in a few lines before it jumps straight to the next concept. I understand the reason might be to pack some much info in a less than 10minutes video, but still it can put alot of people off as many of these concepts are very complex and it can be hard to get a grasp without a detailed explaination before rushing through to the next concept.

I loved the course and learned a lot from it. I came into this thinking that I knew more than I did and I was blown away by how much information there is. However, I looked at it as an opportunity to learn more and absorb everything I can from the course. The only complaint I would have about this course and other courses within this certification program would be the tests and quizzes seem too easy. The final quiz at least should be a test you can take only once to really test the knowledge and add a little pressure to really sink the knowledge into your brain.

It was a good course. I did struggle a little, because it was a lot of information. I think it would be a great idea to add a little refresher at the end of each section. It could be in video form or even just a written-out synopsis of the section. I think this would be good for students, like me, who do a section every couple of days. I may start a course on Monday, and then wait until Friday to finish it. It's sometimes hard to recall what I learned back on Monday, so that is why I think a synopsis after each lesson would be very beneficial.

The setting frequency quiz/test is very vague and provides no discernable parameters which to understand and develop the required knowledge to pass the assessment. Extremely frustrating and does not faciltate critical thinking and accurate problem solving. There's no feedback to help the candidate understand their mistakes and more importantly how to correct them. I.e. what is acceptable and why most importantly what is not acceptable and why.
Other than this, these courses are very well done. But the above is EXTREMELY below average.

Incredibly informative course giving a broad overview of network fundamentals, basic troubleshooting, and giving an understanding of the 5-layer system while also providing information about Cisco's 7-layer model.
Rated 4 stars because there are some fairly minor inconsistencies with video quality - some of the earlier videos don't include subtitles, while others had multiple corrections added; later videos don't have this issue, and it's nothing that detracts too much from the course itself - highly recommended.

The course was good. It was full of lots of good information, and it provided a good framework for learning about networking. However, I felt that some of the assessments were faulty and it caused a lot of frustration, not just for me but for many other people taking this course. I hope something is done to fix those assessments. Also, I wish there was more hands on learning. The course was very conceptual, and although the diagrams from the videos helped, it wasn't enough to help provide a deep understanding.

I really enjoyed this course and the complexity of it as well. I would have liked to have something at the end that would give a broader view with examples of how each of the parts of this course worked together so that it was easier to understand as a unit. Although I got through it and understand the individual parts, I found that sometimes it was taken for granted that you would have an understanding of that higher view when advancing to the the next videos. At least as far as the tech language went.
