Thank you so much:-) Overall this was a great course, it was just very hard!

This was a great course learn so much about how network works, solving problems in a network, verifying connectivity issues on different operating systems.

This was a great refresher and taught how a packet gets from one place to another I'm learning so much!!!

I learned so much in these lessons.

this course was trivial I learned SO much.

I didn't understand at first why I was learning so much about data transmission until near the end of the course.

computer networking in 15 reviews

Thanks for all One of the best courses on computer networking.

it really helped me hone my basic knowledge of computer networking.

I have learnt a lot in computer networking.

Pros: a lot of knowledge in many aspects of computer networking.Cons: the course is too much theoretical and a little of practical tips are taught.

I feel confident I could now explain the basics of computer networking to anyone.

This course pushed me to learn a ton about computer networking and how the internet works.

If you take this course, and REVIEW the notes after each lesson, you will learn so much about networking, from its very finer details (dynamic host configuration) to the general concepts (network layers, Wi-Fi) that will really help you understand the way computer networking works.

From physical communication of bits to explaining how the Cloud works all of these courses are very informative and help greatly in understanding computer networking!

lot of information in 10 reviews

This covers a lot of information, but breaks it down in what I found to be a manageable format.

That's a lot of information in a small package.

A lot of information.

Great course, Packed with a lot of information to learn.

Its a lot of information dont get discouraged keep going even if you have to watch, read or whatever you need to do to get through this course.

It contained a lot of information and I feel that it was enriching.There was a problem with one of the modules.

A lot of information but well taught!

Great course, a lot of information to learn.

at times in 8 reviews

I found the material interesting and the instructor clear and engaging (albeit corny at times).

very difficult at times This is a vast improvement over the first course, and I really appreciated the scope and depth of information here.

Could be frustrating at times with the depth of information given, but really valuable.

It was difficult at times.

Daunting and at times difficult, especially for a newbie to tech, but also, incredibly fascinating.

The interactive quizzes were fun, if a little difficult at times.

This course was tough at times especially when it comes to learning about Subnetting but overall I loved it and I felt like a learned a lot!

It is very challenging at times and has a few bugs but overall all it was fantastic.

it support in 7 reviews

this course has expanded my knowledge and understanding of computer networking from the perspective of an IT Support Specialist and has provided me with applicable skills to become a more effective and marketable technician.

Types of networking technologies etc This was my hardest course so far in the IT Support Certificate with Google.

I'm really looking forward to applying my newfound knowledge to the test at an IT Support job/internship!

I have learned a lot so much so that the IT Support Specialist at my job thinks he should take this course as a refresher.

exellent there are tons of materials and protocols, great for knowing how networks and internet works This course helped me learn the foundation of computers now i can help people and not question my own response to their questions This course was very challenging I have learned many useful things about Computer Networking that I will apply in my future job as an IT Support Specialist.

By far the most important course in the Google IT Support Professional Certificate.

I would say this Google IT support course an excellent course, besides all the instructors itself from Google engineer that makes more legit.

feel like in 7 reviews

Feel like I definitely need some "hands-on" experience to really make sure I understand the material.

I feel like this is very intense for a 2nd Course within the 6 Course program, but this is still a good course to go through and make sure you get a great understanding of networks and the Internet, among other things.

I learned some new stuff that I had only known peripherally before, I feel like it was a good in-depth course on networking!

I feel like the spent more time writing puns for the lectures than they did on the actual material or the assignments.

I like the videos, but I feel like I'm often forced to do a lot of my own research to figure out how to solve problems.

I listed definitions and processes, but feel like I did way more work than I was suppose to.

much rather do this than cramming professor messier A lot of information, but i feel like i fully understand core networking concepts.
