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.

This was a very fun course! I really enjoyed the style and pace of the information given. A lot of technical information was given while the course made it easy to take in and comprehend the material!

T​he material prepared by Google is dense, well organized and well presented, and very engaging. There were some errors in the course material, as well as in the quizes (I raised some of them, others were years old). I would rate the Google course 4 stars because of this.

H​owever Coursera "mentors" and the Support Team get 1 star, and that's just to be polite!

I have been prisoner of this course for 2 weeks, just like hundreds of other learners, due to problems with the last graded plugin "IPv6 Compression". There have been hundredes of complaints, and we received no useful help during that time! Even more frustrating was to find in the discussion forums for the week 6 that the same issue happened last year, and the year before, and the year before!

M​ore than that, some of the errors I raised were raised before, and still not fixed (one of the issues was in a quiz regarding TTL decrement). Even though I raised them again, I have few hopes that they will be fixed, continuing the confusion that some learners experienced when contacted by a "mentor". By the way a mentor is an "experienced and trusted adviser"​. That is not I have experienced! I suggest going with "customer support", and maybe I will be more forgiving!

Words are thrown around interchangeably and haphazardly too often for something supposed to be so logical. It doesn't have to be dry but I felt it was made to be so personable that info came out confusing and sloppy at times. The quiz questions felt more focused on learning your specific cue cards than the actual universal knowledge. Sometimes it felt the questions were more tricky than the info itself. Plus, when you get a question wrong it doesn't tell you what specific video to double back to, it just lazily tells you it's somewhere in the entire section. Sometimes it's obvious where the question will be but often things are thrown in randomly to the weekly modules. I found myself confused after watching 7 minute videos only to head to youtube and getting a better explanation in less time for many of these subjects. The info was basic enough for beginners but I felt it left out more practical knowledge. I learned about subnets but I can see subnet addresses on my personal computer but I feel based on what was taught, that isn't where you go to change it? I don't even know? This felt more like a data dump than teaching. I know more but I wish I could have learned more of how to apply it.

In multiple places, it felt very disorganized and in multiple places "I should call out" completely reverses what was said before.

Some spots felt like the videos were out of order, a topic was presented then the opposite was presented, but then it was switched back to the first topic. Don't explain dynamic addresses switch to static and then return to dynamic.

If there are 13 AUTHORITIVE root servers say there are 13 authoritative root servers. Don't say there are 13 root servers and then say "I should call out" there are more than 13 root servers. If VPN is not a protocol don't call it a protocol and then have "I should call out" it's not really a protocol. If it makes the topic easier to understand state that a simplified way is this, or at one point it was this way, but now we have expanded to this way.

I want to go into networking and taking these courses to get started while working on certificates for networking, but this course was very confusing and difficult. Even after already taking networking classes. I considered giving up since everything was all over the place.

Lots of basic errors that weren't corrected in the videos, simple errors that make it difficult for people learning for the first time. Ex: 1+1=3 then a window pops up saying "Oops! We meant to say 1+1=2" there are way too many of these throughout all the IT support course. Another big issue is that when I get stuck and go to forums there are so many others lost and confused by the videos and explanations given (understandable with it being tougher material) but then there are no instructors/mentors responding to help! There are tons of unanswered threads with people like me who couldn't grasp some of these concepts because they weren't explained enough and the only people answering them are other students taking the class who found it through youtube or people who already know the info and are just taking the class to refresh their knowledge. Really good program but there are too many errors in my opinion and too much room for improvement; it seems like they just wanted to get it out rather then get it done right.

The entire course was disorganized and poorly taught. The information is good, but if you truly want to learn what he's teaching you'll need to take the time to research each topic thoroughly - wikipedia and youtube are good sources.

Mostly the teacher just stares at t he screen reading a script. Minimal visual aids means most of what he says is just blah blah. I had to read articles and go to youtube and find videos on the topics in order to understand what he's mindlessly rattling on about. He uses technical terms for several videos without defining them. You get quiz questions on topics he's yet to even cover.

Some of the quizzes are buggy and will give you a 0% even if you get all answers correct, and requires repeated attempts to pass. The Network Channels quiz in week 5 took about 30 tries before it passed me, even tho I got every question correct. This test was so easy it took only 1 minute to complete and a child could pass. So frustrating.

The instructor is hard to watch and instead of saying "IP A "he reads the entire IP ,you try and stay attentive while someone reads out long strings of numbers .The test is problematic ,doent give help after wrong answerr or any input at all (lazy)or comprehensive instructions on how to use buttons inserted for 1 quiz only .The personal story interstitials are a waste of my time ,not motivational and production $ could be used to better explain concepts you rush through so I have to listen to these peoples stories about their lives .Spell check and reasonable font size within testing would be a professional touch as well.So far class seems old and cheap .Reading materials with graphic aids and not just supplemental reading would be helpful.

Have to reitterate how poorly this networking segment is written !

Stopping mid explanation to insert new concept before finishing initial explanation is ridic and I find the instructor detestable.

L​ot of material thrown at you, very simple things are given explanation and other more complicated things you need to understand are just glossed over. For example a network switch is described as being a part of the data link layer, and as someone completely new to networking I didn't know if a switch was an actual piece of physical hardware or if it was computer software. And some assignments provide very little useful knowledge while just being tedious, like the IPv6 Compression assignment. I would have very much liked to have it explained in more detail how to actually set up some of the things talked about in the course. HOW do I configure a router to use NAT? HOW do I set up a VPN server for a buisness? HOW do I make my home network work better? Overall it was fine and you did learn some good things, but definitley was not a course I was super motivated to go back to.

I found the instruction needlessly confusing. The instructor sort of rambled making no distinction between needed facts and ancillary information. When questioned, i was asked to respond to questions based on one sentence of content. Their was little to "drill down" on as everything was a mono-tone of boring lecture. Yes, the information was correct, but much of it was presented without benefit of instructive example. Just a little time taken to show the "how" of operations would have made a great difference. Instead, i struggled to maintain interest and in the end i settled for the passing grade ( 92 ) instead of pushing for my best. I felt like this just had to end. Worst, i started to doubt myself and the value of this course. But, shaking that off i intend to go to the next level and do well their. Bits and bytes was disappointing

While a lot of the information in this course is useful, it's presented very densely and with a fair amount of superfluous information surrounding it. I appreciate the desire to include the origins of technology, but there's a point of diminishing returns on the benefits of understanding something that no one ever encounters or uses as a modern day technology specialist. The information that was relevant was incredibly useful, but the presentation, particularly the horrendous puns and jokes that are delivered through poorly held back laughter, was irritating enough that I almost completely abandoned the course and cancelled my subscription to the specialization. I know that's a stupid, petty reason to dislike it so much, but I also don't think I should highly recommend something that I often found inaccessible or off-putting.

I feel that the course titled The Bits and Bytes of Computer Networking wasn't really what I was expecting it to be. The lessons did not really go that much in depth and I felt that I really didn't learn the absolute fundamentals of computer networking. In most cases throughout this course, I had to find additional materials to help me understand what the course was trying to present to me. Even the provided supplemental readings (with perhaps the Wikipedia articles as an exception) failed to give me any kind of understanding of what I was supposed to learn in that particular lesson. Also, I feel it would have been beneficial to me, as a somewhat networking novice, if the lessons were more hands-on with scenarios of what I might encounter if I were in a networking role.

Honestly, I was pretty disappointed in this networking course. In my opinion, the Coursera team should overhaul this course. Just having one instructor talk about abstract concepts in 90% of the videos isn't helpful for grasping and cementing in new concepts. I'm a pretty visual and hands-on learner, and this course was 90-95% all auditory. These were difficult abstract concepts that desperately begging for visuals, animations, real life scenario videos, simulations and virutal computer labs to help cement concepts. I don't feel I've learned as much as I could have. I'm really hoping the next course 3 OS & other 2 courses going forward won't be as frustrating as I work toward my Google IT Support Pro certificate.

While the overall course was great, I find that some of the plug-ins were not explained properly and this accounted for the low score. Please see below.

Week 2: Graded Assignment - Plug In: Routing Paths and Subnet. It wasn't clear that if an incorrect answer was given, I had to restart the test.

Week 5: Graded Assignment: Wireless Channels. Each question was answered and checked, submitted the final results several times and my score was always 0. After several attempts, I reviewed the discussion forum and saw that this problem was not unique to me and I should not have any issues if I used FireFox for this portion of the assessment. I did and received a correct score after my 2nd attempt on FireFox.

These were pretty cool courses that offer a lot of knowledge but the part where that talk about getting you information out to companies to help you start your career is fully true. They send you a survey that you select the companies you would like to share you information with out of they're selection, and that's it. There is no other follow up or anything as far as I've seen but I've been done with the program for workin on four months no with no other leads to helping me start my career. So it's great maybe to help boost a career you're already in but DO NOT TAKE THIS COURSE if you are using it to help START a career. Hope this helps some people out like me looking for a way into the industry.

Concepts are not explained in detail, and even external links for additional learning are often covering concepts that are far past the level being taught in the course. Honestly starting to think that this course may be a waste of money, especially if this certificate isn't recognized by any employers. So much information is either missing or just skimmed over. The videos are lacking detail information and it's applications, and seem like a series of YouTube videos teaching old people how to use a smart phone, rather than a real class. Then the tests come asking questions on topics that weren't even fully covered in the videos or readings.

I like the course and the video learning. But, the labs are not good!!!!!! The directions are confusing, you assume people know what you mean, we are trying to learn and you make these tests and labs so damn confusing. Why not have a video tutorial or a walk trough tutorial option, cmon Google!!! I am sitting here trying to do the next work quiz and the directions are written so half ass and confusing, there is a game to write the instructions for a Peanut Butter and Jelly sandwich, Google you should look that up and write your directions accordingly!!!!!!!!!!!! Please fix the labs give people an example of what you mean.

The peer review graded portion was just crazy to do. Keywords and definitions are basically all it takes to pass it while putting in key phrases of how a packet is transferred. To convert 10 IPv6 addresses was just plain over the top. The worst part about it, and I didn't catch this until my 3rd reset, it is CASE SENSITIVE! Come on, Coursera/Google. This 2nd course needed to be like 10 weeks with the lack of amount of information that was given. As long as you memorize key words and phrases, this shouldn't be a problem week. I really don't think I learned any more than I already knew with this course sadly.

So far this course is only ok. I do not feel like it is giving me a solid foundation. They try to cover so much information, a lot of it very technical in a little time. They tell you to rewatch the videos and read the supplementary reading. The supplementary reading is ONLY wikipedia. And do not get me started on who scripted this--I don't know what I am going to do if I hear the words "I should call out" or "spoiler alert" one more time. The teachers, during the lesson videos seem very inauthentic. Google would have been better just letting the teachers free style the lesson.

Giving it three stars . Some more interactive flash would have made the course better. I also dislike the fact that while testing with the plug in if you make one mistake you have to reset the whole plugin. Also 10 IPV6 to translate in plugin then another one on final come on . Four translations would have been enough. An area of improvement would be add video on Ethernet RJ45 twisted pair creation . Maybe a virtual module where the student correctly has to form twisted pairs. Could have added some info on ping of death , ICMP flooding, port probing etc...

T​here is allot of unneccesary talking, that makes it a little hard to follow. Especially for those who may have a learning disability. I understand the instructor in the video is trying to explain why and how he got interested into the course. But all of the uneccesary added talking should be saved at the end once we have finished the quizes and tests. I personally find it a little hard to follow when there is too much information given at a time. It's giving way to much to remember. It's almost over whelming.

Course material not covered well in videos much guessing you have to do on the test !

to hard to get help maybe a study group is needed from the start. content not clearly explained?

instructor need to make things clearer ..too much jumping around from one concept to another before we have a complete grasp of what he trying to teach or how things work together ..quizzes help ..not as easy subject to teach any way.

Way too difficult follow-up to Course 1. I've been simultaneously working on Course 3 to stay afloat in my intensive IT Support program using this Coursera material and I'm finding that Course 3 material is much simpler. The concepts simply don't build upon previous concepts in a way that makes sense. Also, a lot of the quiz questions are not covered in this course and some of them deal with 20 year old technology.

T​his course was full of information and history about how networking happens. The downside to this course though is that it gives you almost zero knowhow on how to practically setup a network. Sure having abreviations, history and technical knowhow is good but the course doesn't teach someone on how to actually plug things in and configure a network. I'm a bit disappointed and feel like I didn't learn much.

There is a ton of wasted time in the lessons. The guy repeats himself, gives redundant / useless information, repeats himself some more, and occasionally tries to be funny and cute which just makes me cringe to death. The lessons do not focus on the same information that's in the big quizzes. Like, the videos are about A B C and D, and hint at the existence of E, and then the quizzes only ask about D and E.

Bit sloppy to be honest and for what its worth I don't think anyone with 0 knowledge is going to come out of this course with very much confidence in what they've learned. Networking is pretty heavy stuff for people with no previous experience and this course while it does a good job trying to compress it takes too little time going over a lot of essentials so you can truly understand it.

it was very hard to keep focused the pacing and constant words to learn given to me in an uninteresting way made it really hard to me to retain information I found myself looking back at notes and trying to learn the materials from other sites right after a video because the way the content was provided did not stick with me unfortunately very happy to have completed this course.
