The course was full of useful content but the audio voice wasn't that good and could be tiring at moments.

I'm getting a lot of the terminology and information that I needed, although I still have some questions!

This was awesome it was easy to understand and there was vocabulary and pics and bullets with descriptions I wish there was a lot more videos like this

In most of the course, the person is just reading out what is on the slides and does not offer any further explanation. While there is a lot of information contained in this course, it is not organised in the best way and also sometimes repeats points unnecessarily.

For a free course, at the beginner's level, it is good enough. Although, the BONUS SECTION can be skipped.

Como introducción no está mal. La estructura del curso esta bien organizada, pero se limita a leer lo que pone en las diapositivas.

I was expecting not only reading the slides, but telling more about the concepts and vocabulary. I know this is a course for Beginners but it can be improved by giving some simple examples so that people can understand better.

It appears that this course was put together by networking students that just copied their course materials into PowerPoint. The delivery was pretty bad. The instructor(s) basically just read the slides verbatim with the occasional departure from the slide to elaborate on the topic. Overall the information is valid, but very very dry, poorly delivered, and not engaging or exciting at all.

Though the course does a good job at explaining the fundamentals and covers all the topics to introduce a beginner to networking concepts, the author does nothing more than reading the ppt. The content is good and just going through the presentation on our own would not have made any difference. Anyways, 5 stars for the quality of content in presentation.

The course is really good for a non specialist; however, it uses some terms that I don’t understand and some complex (non specialist) language. For a free course, I can’t knock it though. An excellent starting point.

First of all, it's a free course that just spans little less than two hours so you can't (and I didn't) expect all too much from it. The information is decent, some parts are good other parts should have been explained further. On quite a few occasions I'm left with the feeling that this course is someone just reading someone else's powerpoint slides. There's no confidence in the speaker and the information very rarely strays from the couple of points and sentences presented on the screen. The bonus section has more confidence from the reader, but never really goes any further than the exact same text that is presented in the slides. If you want a brief overview of a couple of protocols and such, it's a good enough course since it's free and it's not that long.

The guy basically reads the static presentation slides, and when describing things on a particular slide, no labels or use of pointer/highlighting/animations (using a video screen capture such as Screenflick) etc are used to help illustrate what's going on. For example at the beginning in networking topologies, he talks about computer A wanting to connect through to C and computer B is out of action. None of the computers in the diagram are labeled and there is no use of any pointer/video screen capture to illustrate the concept. The tutor clearly knows the subject and I know it's free, but it's a pity that the tutor didn't use all the options available to get his points across in a more engaging and easily understood way. I got to lecture 4 of the first part and gave up.

Class covered a multitude of necessary networking components. Went over definitions, usage and importance. Great for beginners to get the concepts straight. The course has two different instructors. The only thing that was noticeable, is that one instructor talked very fast and the other talked super slow. But the problem is easily fixed by slowing down and speeding up the video. So it wasn't a big issue.

It's a free course so I can't be too harsh but it was fairly obvious the presenters don't have a strong understanding of the material and that many of the slides were repurposed or stolen.

very brief introduction into Networking concepts. I really enjoyed the bonus section . I gave it 3 1/2 stars not because its average, the information is great, but thats all that it is...just information. You really can't expect much else from a 2hr long course.
