I believe this is the easiest lecture to understand for difficult computer architecture and operating systems.

Good

I think this helped a lot in grasping the concept. Thank you.

You can really tell how much heart and soul went into this lecture.

It's great for getting an overall overview of computer network concepts. It was light, yet allowed me to dive deep into the necessary parts.

The lectures are excellent for reviewing the book. Since the lectures cover almost 90% of the same content as the book, you can learn enough from the lectures alone. However, I recommend purchasing the book as if you are paying a tuition fee, reading it first, and then watching the corresponding lecture chapters to review. To be honest, other layers in networking are mostly for certification exams or general knowledge, whereas HTTP is what you actually need to know in detail. I am very satisfied because this course explains all those practical parts. This instructor's lectures are of much higher quality and better for learning than the networking courses taught at most universities. Just because it's a four-year university in Seoul doesn't mean they teach something incredibly grand. This course is simply easier to understand. It is much more substantial than what you would learn in a full semester at university. I think the only difference from university is the amount of knowledge forced into your head due to assignments and exams. If you want to dive even deeper, I suggest purchasing a "Top-Down Networking" textbook, which is commonly used as a major requirement, and studying further. These lectures alone are more than enough to gain all the fundamental knowledge.

I'm really happy because this course seems to build a much more solid foundation than I expected. I highly recommend it to beginners who are unfamiliar with GitHub.

I'm reviewing this for the first time in a while through the lectures after studying with the book, and the lectures are really great too.

The content is difficult, but the lecture is very easy to follow! You explain things so well that even though I know nothing about this field, I'm starting to understand it a little!

I haven't finished the entire course yet, but the explanations are easy to understand, and I'm finally grasping parts that confused me during my major classes! I highly recommend this to beginners.
