Let's Understand Networks with Pictures (2022 ver.)
Network: Easily understood with pictures. Save your time with 'pictures' and 'animations'!
Reviews from Early Learners
What you will learn!
Network
OSI 7 layers
Major Protocols
The basic skill for all developers, networking!
I'll explain it to you in an easy and friendly way 👍
Why is IT theory so difficult? 🤔
If you are new to the IT field, you will soon encounter a language barrier . Since the terms themselves are mostly English-based abbreviations, you have to memorize them rather than understand them. Even if you look at specialized books or YouTube lectures, the pictures are all abstract and it takes a lot of time to understand them. Due to the nature of the subject, you need to know the 'flow structure' to understand it, but you may have had difficulty understanding that structure.
College students, office workers, and non-majors
A network that feels difficult…
"I'm taking classes at school, but I don't know what the content is about. The textbooks are too abstract and difficult to understand. "
- Freshman computer engineering student -
"I regret not having learned the basics of networking before getting a job. I still feel like I only have a partial understanding of networking , and I want to learn it again, but I don't have enough time because of work."
- Junior Developer -
"I'm new to networking and I was surprised by the unfamiliar terminology . Studying development is fun, but there's so much to learn."
- Non-major developer job seeker -
In particular, networks are essential basic knowledge in IT fields such as web development and engineering, and security management, but even students majoring in the field and those already employed may not yet have a clear picture of networks.
A confusing network,
Learn easily with pictures !
We have organized the difficult and abstract network concepts into easy-to-learn diagrams, animations, stories, and abbreviation explanations . We have created lectures so that you can easily understand difficult and time-consuming content in a short period of time using books. Let's challenge together!
For network beginners
I prepared it carefully.
The lecture is structured to help you draw a comprehensive picture of network knowledge that you previously only vaguely knew about.
Explain with pictures
I prepared it so that it would be as easy to understand as possible through pictures. I tried my best to make it so that those who took the lectures on video editing, lesson design, fonts, picture design, etc. could easily understand the content.
We provide lesson plans
We provide PDF files of the entire syllabus for each unit so that you can conveniently take notes and study while watching the lecture, and conveniently review after class.
So that you can organize what you have learned
Each class video has a 'summary' section. Towards the end of the class, we summarize and mention the main points and key contents once again to increase the learning effect.
Learn how it works with your own eyes
The network operation process and principles are presented in an animation format. It helps you understand the content much more easily and intuitively without having to read a book for a long time.
Detailed Curriculum 📚
💡 Learn about the overall understanding of networks, the 7 layers of the OSI model, and the major protocols between each layer.
Network Overview
Before learning about the operation of each layer in earnest, we will briefly explain each layer of the OSI model and organize essential terminology.
Physical layer
Learn about the role and related content of the physical layer, the lowest layer of the OSI 7-layer model, and about hubs and repeaters, which are network devices related to the physical layer. You will also learn about the main protocol, Ethernet.
Data link layer
Learn about the role of the data link layer, the second lowest layer of the OSI seven-layer model. We also cover switches (switching hubs), which are network devices related to the data link layer.
Network layer
Learn about the role of the network layer, the third layer of the OSI seven layers. Learn about routers, network devices related to the network layer, and routing operations. Also learn about the main protocol IP.
Transport layer
Learn about the role of the transport layer, the fourth layer of the OSI seven layers. Learn about TCP, the main protocol of the transport layer, and the various controls and operations of TCP and UDP.
Application layer
Learn about the role of the application layer, which is the upper layer (presentation, session, application) of the OSI 7-layer model. Learn about the main protocols of the application layer.
Wireless LAN
Learn briefly about wireless LAN.

How can we easily understand complex and difficult networks? As someone who has struggled with such issues, I created this lecture. I have long thought, 'It would be great if there was someone who could easily explain networks with pictures,' and I started this lecture with the thought, 'I will become someone who can create such a lecture.'
In addition to the 'Understanding Networks with Pictures' series, you can also find news about IT-related content and lectures on our YouTube channel . The 'With Pictures' series lectures are still being prepared, so if you would like to hear more news, please subscribe.
Q&A 💬
Q. Are lecture materials provided?
Lecture notes are provided. Lecture notes are provided for every unit in PDF format, based on the lecture content.
As the title of the lecture suggests, we put a lot of effort into creating the lesson plan as ‘drawing’ is important.
Q. Is this a lecture that non-majors can also take?
Yes, even non-majors who are interested in networks can easily listen to it. We have prepared explanations with pictures to explain difficult content as much as possible, and have prepared it so that you can easily listen to it through repeated study.
Q. What are the benefits of taking this course?
Beyond understanding the network in parts, you can easily understand it through the overall picture and structure.

100% enrolled필요하기도 하고 궁금한 내용이라 강의를 수강했습니다. 강의 내용을 쉽게 전달하기 위해 세심하게 만드신 시각자료를 공유해 주셔서 좋습니다. 어려운 내용이므로 시각 자료도 계속 보면서 복습도 하겠지만, 방대한 내용을 이렇게 단기간에 좋은 자료와 함께 전달해 주셔서 부담이 덜 합니다. 좋은 강의를 제공해 주셔서 감사합니다 :)

안녕하세요, dgh12님. 강의가 업로드되자마자 수강해주시고 완강해주신 것 같아서 제작자 입장으로서 매우 감동이었습니다. 앞으로도 어려운 내용의 지식들을 쉽게 전달하고자 노력하겠습니다. 수강해주시고 좋은 후기 남겨주셔서 정말 감사합니다! ㅎㅎ '그림으로 이해하자'시리즈는 계속 제작 중에 있으니 많은 관심 가져주시면 감사합니다 : )!

7% enrolled목소리가 차분하시고 강의력도 너무 너무 좋아요! 대학 교수님이 알려주실때 이해가 안돼서 예술하는 개발자님의 강의를 듣게 됐는데 직접 그림으로 도식화해주셔서 이해하는데 정말 큰 도움이 됐어요ㅠㅠㅠ정말 감사합니다👍🏻👍🏻👍🏻 책으로 출판되면 구매하고싶을 정도에요..! 예술하는 개발자님 이런 강의를 만들어주셔서 너무 감사해요👏🏻 관심있으신 분들이라면 고민말고 이 강의 꼭 추천드립니다!
- 데브아틱스Instructor
안녕하세요, 하은님. 긍정적인 후기 정말 감사드립니다! 많은 분들이 학부생 시절때 수업 내용을 이해하는데 어려움을 겪으십니다. 이에 착안하여 다른 어려운 IT내용도 '그림과 애니메이션'으로 쉽게 이해할 수 있게끔 강의를 제작해보겠습니다 ㅎㅎ!

100% enrolled완전 기초 강의. 전산을 모르는 대학생들에게 어울리는 강의 입니다.(시험) 하지만 책을 읽는 듯한 강의자의 목소리와 설명의 디테일이 조금 부족하여 깊은 이해를 주기는 부족해 보입니다. 교양 네트워크 강의를 읽어주는 느낌이 들었습니다.
