Memorize and finish the core network theory - Basics
From TCP/IP to HTTP! This lecture is for those who lack basic network theory and want to understand major theories by memorizing them. You can do it!
This course is prepared for Beginners.
What you will learn!
Why you don't need to memorize the OSI 7 layers
TCP/IP network structure
Basic understanding of the Internet
How the Web Service System Works
The Role of Port Numbers
A series of processes from packet creation to destruction
Network, memorize it easily and quickly!
TCP/IP Network & HTTP in 7 Hours 👨🎓
network theory,
I have to learn though... 😥
Why was your network study difficult ?
Networks, both as a term and as a concept, seem too complex and abstract .
I struggled to learn what the OSI 7 layers were, but it just took up a lot of time and I gave up.
From TCP/IP to HTTP, can't we just quickly look at what's what and think about it?
👉 If so, you need to change your study method !
Network? Don't think too long.
You can finish it even if you memorize it! 👨🎓
Many people who study about OSI 7 Layer find it difficult and give up on the network. The reason is very simple. It is because they tried to understand abstract concepts that are not specific. If you were to ask those who are reading this article, “What is love?”, would you be able to answer easily? Above all, would you be able to call that answer the ‘correct answer’ ? The reason we find networks difficult is because we are trying to understand theories that are not specific.
So I prepared it. If you want to study networks quickly and effectively, first of all, memorize and finish it! It is more effective to memorize quickly and build up basic stamina than to spend too much time understanding it. Of course, even if you memorize and finish it, you will not be lacking in understanding.

- Bit-wise logical operations can be performed.
- Binary can be converted to hexadecimal.
- We know that 1024MB is 1GB.
- I know the difference between a Process and a Program.
- Have you ever heard of the term OSI 7 Layer?
- We know that there are User mode and Kernel mode in general purpose operating systems.

We help you build your 'basic stamina for networking' 😊
Studying networks is important, right? However, when studying networks, it seems that there is a tendency to not understand the conceptual aspect and get caught up in it, preventing you from moving on to deeper theories . While I was teaching various lectures on my YouTube channel, I met many people who had difficulty understanding networks.
Don't try to understand, just memorize and finish first. The goal of this lecture is to help you understand networks naturally as a result of that memorization. By building up the basic stamina to understand networks that are difficult to understand even when reading books, I hope that you will be able to understand the meaning more easily when you read books related to TCP/IP networks or study more in-depth content in the future . I will quickly and efficiently tell you what I have learned through studying and encountering development for a long time.

14% enrolled이강사의 모든 강의가 외워서~ 외워서~~ 라는말을 저는 참 싫어합니다 그러나 결제했고 돈아까워서라도 들어보자 해서 듣기시작했습니다 이분이 말하는 외워서 라는뜻은 그만큼 중요하기때문에 외워서라도 꼭 알아야 한다는 거였내요 평점을보고 주작된 평점인줄 알았습니다 그러나 그의미를 초반에 알려주고 시작하니 의심이 사라졌고 강의를 쭉 보게되었내요 이분강의를 세일기간에 대부분 구매하여 아직 보진않았지만 요강의만큼은 인정합니다 추천합니다

외워서 끝낸다는 것이 흔한 광고문구라는 것을 잘 알고 있습니다. 그럼에도 이 말을 붙인 것은 저 나름대로의 이유와 근거가 있었기 때문입니다. 그런 제 생각을 인정 받은 것 같아 기쁩니다. 어떤 이유로 이 강의를 선택하셨는지 알 수 없으나 네트워크를 포함해 가상환경에 대한 공부를 해야 하는 상황이라면 꼭 응용편까지 완벽히 암기하실 것을 권합니다. 그 암기의 결과는 업무에서 바로 확인하실 수 있을 것입니다. 고맙습니다. :)

100% enrolled1. 네트워크 공부를 해봤으면 네트워크라는게 개념이 잘 안잡히고 이해가 확실하게 되지 않는 느낌이 많이 난다는 것을 알거임. 강의에서 그 이유를 알려주고 제대로 이해할 수 있도록 수업을 진행함. 2. 네트워크 라는 것에 대해서 인프라 입장, 프로그래머 입장 두 가지 관점으로 이해할 수 있음. 3. 강의가 이미 준비되어 있는 ppt로 진행하는 것이 아니고, 수업을 진행하면서 직접 그림을 그리면서 설명하는 방식이라 이해가 훨씬 편함. 4. 내가 이해한 내용을 그려보고 강사님 그림과 비교하면서 내가 제대로 이해한 것인지 복습 가능.
