Instructor has a thick accent that makes it difficult to understand the videos. On many occasions, I needed to stop and rewind the video just to understand what he was saying. The lecture videos, also, do not add much value to the instruction; often, he is simply reading the content on the slides. Lastly, this course assumes familiarity with polynomial division and binary math. On these topics, the provided examples were not sufficient to understand how to perform the necessary operations. I found that I needed to consult outside resources to fully understand the material and answer the quiz questions correctly.

This is the worst course about networking on Coursera. Not consistent, lots of bugs in presentations, the assignments introduce cunfusion and the author seem not to be competent for teaching this stuff. There are much better courses out there. You can find better explanations on yt for free. If you don't want to waste your time and end up cunfused - just do not enroll.

The accent of this instructor is unbearable: you will not follow the content of the lectures , instead it will take you tons of effort to understand his pronunciation!

I barely understand the lecturer, Information provided is not enough to answer all quiz questions (especially of the final one). I believe this course is useless for a beginner. Providing links to RFC and referring to some pages of Tanenbaum's "Computer networks" is unacceptable in a course (at least as a main source of information): I would never sign up for this course if I knew it is just provides me information on what to read. I can google it after all.

Not useful at all!

very abstract. No detailed explanations or practical examples were taught. I took lot of other courses in coursera but this is not a typical coursera course. very much disappointed.

the information presented in the lectures is completely inadequate and does not explain the subject.

Let me tell this honestly. The course structure and other features are all good and very useful. I am a visual learner and I preferred this online platform to learn for that reason. But, I am not able to understand what he says. I have to spend more time in understanding the words he use and thus I am not able to learn this course through video lessons. I appreciate his effort but i tried my level best to understand it and I am not able to.

The course did boast of a good content. But unfortunately, I felt that the explanation of several concepts was too concise and not up to the mark. Also, I found the peer-graded assignments to be very inefficient and misleading. Also, the required minimum score of 25 out of 31 points was way too steep, coupled with a threshold of very low maximum points (1 or 2) assigned to some questions, which should have actually carried more weight-age. Also, I found the grading scheme to be quite confusing. The peer-graded assignments should be completely eliminated, at least in my opinion!

difficult to understand the professor

absolutely not for beginners assumes way too much prior knowledge

Very very very boring. Please don't waste your time. Instructor only reads slides.

Worst teaching style. Just reading slides

It is a good course to cover the basics computer networking. It is simple and the workload is less. Try to go through other sources simultaneously to get in-depth knowledge on the topic.

Really fantastic experience learning with Coursera. Awesome study materials and choice of syllabus. Just the perfect one for new faces in this field. Keep it up Team Coursera!!!

This course helped me build foundation of computer communication. In the end, I feel like I had fun with interesting contents and assignments questions.

Great course and assignments! Had fun learning and answering quizzes. Professor Zhou covered all the m=important points in his slides. Thank you again.

Very useful and very interesting course, helped me a lot in understanding the subject thoroughly.

Overall great course! Leart the fundamentals of communucations. Many concepts were explained with powepoint presentations, and good links and books were provided regardingcthe topic.

Through the whole content of this course, I learned a lot new things and I thought it will further improve my existing IT skills and the quick way of answering MCQ. Thank you so much.
