Introduction to Networking

Don't take this course. I really don't recommend this course to anyone who never learned computer network. Rafail Portnoy should explain materials in the course more and more.

The reason why I felt like this is because I also took Computer Hardware and Operating Systems by Daniel Katz-Braunschweig and his class was too GREAT! He teaches with a lot of easy examples and fully explains why, what, how.... and so on.

On the other hands, all the videos of Rafail Portnoy's class are shorter (videos are around 30 mins each) and of course less explanations, so I kinda had hard time to understand what's going on.

This is very iportante for computer course in programing language. And I am very intresting of this course. I feel so proud of , I am doing tis course. And computer networking is a globle networkink course. And it's needed to everbody currente time.Iam very exiting for this course. And wand do this course seriously with exitment. And which persones provided this course. I want say him so thanks. You are very kind heart and gentlman for us. So I want to say you and your teem so thanks.this time computer and smart gajets working around the world. This knowledg is very important for coding and software dewlopment. And thankyou . Providind this chance for learning computer networking course.I want say again so thanks.

Rafail Portnoy is a magician in teaching computer networks. Awesome experience with the course. If you are struck at networking just enroll here.

This is the second course that I have taken on the subject of Computer Networking. Overall, I thought everything here was pretty straightforward, and the course topics were well-organized. I was able to move along the course fairly quickly and finish the specialization.

The course is really good but I wish for a simpler example It explain all layers

you may get bored in the middle of the lecture but

don't worry it is normal

and highly recommended this course as one who doesn't know anything about

Networking

I will recommend this class to any one who want to have a good basic of the networking , this is good introduction to networking , the class is very instructive , very comprehensive the OSI model is very well explained as well as routers , switches functions , network concepts and design

very good course. i helped me a lot. i think some of the examples could be explain in more better way and also some of the concepts could be made easy. the overall course was very good. i appreciate the effort of the teacher. thank you

one of the best courses i've taken in the last decade in relation to tech.

complex subjects broken are broken down in way which makes sense

and builds solid and essential knowledge quick.

5/5 !

Very good course structure.

It is suitable for both beginners and experienced persons.

I recommend to take this course not only for knowledge but also for career in near future.

The course is very helpful because it has a good explanation of networking from basic. It is self-paced and learns as per your preferable time.

i have always wanted to know how computers communicate with each other and finally, I have the chance to learn this and more amazing stuff

Nice platform for free knowledge

Thanks for this to spread free course

After getting this i gained various type of knowledge from home

Good feature - containing Powerpoint side with simultaneous presentation.

Easy to understand.

Contents are good ordered.

I think it's great material but because I'm on a limited budget can't afford it and it doesn't allow me to keep score

I took this course to get the undergraduate credits. The quality of the material was excellent and the teacher answered my questions on a regular basis. I would take more classes like this one from the teacher.
