"This really is a great course. The course effectively deals with one of the biggest problems with the 'IT' world: Speaking in another language that non-tech outsiders don't understand. Some people may feel that it is too simplistic and slow-paced, however, they lack the above understanding. Thank you for your efforts!"

- Rad

"Wonderful entry-level course. I recommend this course to anybody who is just starting in Networking. I also recommend it to anyone that works with computers every day. Learning the basics and understanding of networking is great knowledge to have. Alton responds to all questions asked, for that I applaud you. Without hesitation here is your 5-star review"

- Michael

July 8, 2022
Just getting started but seems like such a kind teacher and like I might actually be able to grasp this complicated subject with their style/approach!
July 1, 2022
It helped me understand the overview about a basic networking at place of beginner. Thank for teaching!
June 26, 2022
The course is fantastic, helpful and interesting. If I had any suggestions it would be a bit different tone in delivery as sometimes its so smooth (ASMR like) I actually fell asleep :D . Other then that I have nothing but the best to say about the course and the instructor. It is quite clear that he is quite knowledgeable and has invested a lot of energy into this. I would and will recommend this course to anyone I run into who might need to learn about networks from ground up.
June 20, 2022
Absolutely Amazing! You delivered the content exceptionally well! I highly enjoyed listening to your lectures :)
June 15, 2022
The experience of the instructor as well as his manner of presentation reassured me of a comprehensive and easier to digest course, as opposed to the Google IT Networking course.
June 11, 2022
I am really enjoying this class. The material is in great detail and easy to understand making it easy to pick up. The labs are really fun and great too! I will most definitely look for other classes by this instructor!! Thank you, Mr. Hardin for all of the work and time you have put into these lessons!!
June 10, 2022
This course is well structured, well explained and is taught by an instructor who knows what he is talking about. Besides this, the course is updated frequently by the instructor so it is not outdated. Besides that, there are quizzes and ideal combination to learn things quickly.

Very clear and easy to understand presentation, slides are also good to help refresh what was learnt.
June 9, 2022
The amount of effors the intructor has put in with real life cable examples to make the student understand concepts is commendable !
June 4, 2022
Very informative. I am learning a lot and the teacher is really good at condensing information. Also really appreciated the live demonstration.
June 1, 2022
Very clear and understandable. The illustrations are extremely helpful in digesting the information completely.
May 25, 2022
I have learned OSI model a long time ago and in this course I am having the opportunity to update myself and learn many things in the current language. excellent teaching and great content
May 24, 2022
Great introduction course, I am a biomedical engineering but migrating to IT applied to Healthcare and it is impressive what can you develop when you understand the basic concepts of IT, Communication Protocols, connections etc
May 23, 2022
Well i have to say a lot of learning and would love to recommend to people who are interested in computer networking field as it cover every topic right from the scratch. Explanation was solid and clear Wide range of diagrams Clear explanation in detail Labs for simulating real-time scenarios(cisco packet tracer) which is really helpful Overall fullly satisfied with the corse and Special thanks to Alan.
May 18, 2022
It was the perfect mix of high level and details needed for a Non-techy trying to understand the basics/fundamentals. Definitely will be looking into your other courses.
