Reviews from Early Learners

What you will gain after the course

  • OSI 7 layers

  • TCP/IP model

  • HTTP/HTTPS

  • HTTP2, 3, WebSocket

  • Gateway, Proxy

  • DNS

Is there knowledge that only developers with a computer science background know?
Even non-majors can learn with this course 😎

If you've ever had these concerns, pay attention!

🫠

I want to learn the basics of networking, but the textbooks are too thick.

🤔

Even if I learn all the specialized knowledge, I don't know how to use it in practice.

🥲

Sometimes I feel embarrassed because I don't communicate well with server-side developers.

Is computer science knowledge only for those who majored in it?

Anyone can learn it, even non-majors! ✨

The OSI seven-layer model, the TCP/IP model, HTTP, WebSockets, DNS, proxies... These are essential concepts for anyone aspiring to become a web/app/server developer. Computer science majors are equipped with this fundamental knowledge.

Non-majors who haven't studied computer science often assume that majors already know something amazing. However, with careful study, even non-majors can acquire the same level of specialized knowledge as computer science majors. I'll teach you the essentials, focusing on practical knowledge.

If you can't answer "yes" to any of the three questions below, then join this course!

  • Do you know what process the data you send goes through before it reaches the other person's computer?
  • Can I analyze HTTP requests with the Network tab without asking my backend developers?
  • Can you ask your backend developer for the headers/methods/response codes?

I recommend this to these people 🙆‍♀️

People who are not majoring in the field but want to become web, app, or server developers

Front-end developer who doesn't know much about back-end

People who want to know only the major topics that are frequently used in practice


Lecture Features ✨

The concept part is explained with pictures in the lecture notes.

We provide server code for practice .

Check the data actually being transmitted with Wireshark .

Try sending HTTP requests/responses directly and check through the network tab that it works as per theory.

Among the thick network books, we have removed the less frequently used parts and condensed and explained only the frequently used parts .


Learn things like this 📚

OSI 7-layer + TCP/IP model

Checking the OSI 7-layer model using Wireshark

HTTP request/response header analysis

Understanding Cookies/Cache/CORS
Terms such as DNS, VPN, Proxy, Gateway HTTPS, HTTP2+3, and WebSocket


With two-way communication
So that you can understand better.

The great thing about my lectures is the Q&A.

  • We aim for active learning through questions and answers .
  • If you have any questions, we will respond within 48 hours.
  • We are constantly updating and supplementing our lessons with updates and news to address frequently asked questions from our students.
  • Feel free to ask questions about the lecture content while studying. This will help you understand the material better!

Things to note before taking the course 📢

Practice environment

  • Operating System and Version (OS): Based on Windows 11, but other operating systems are also acceptable.
  • Tools used: WireShark latest version, node.js LTS version

Learning Materials

Player Knowledge and Precautions

  • You just need to know what a LAN cable is.

Expected Questions Q&A 💬

Q. I heard that you have experience with connecting a LAN cable. Is that true?

Yes, I will start the lecture from the LAN cable.

Q. Will I really gain the same knowledge as a specialist?

You will know less than a major, but you will save time by not having to learn useless knowledge that a major learns.

Q. Is it useful for backend aspirants as well?

Yes. You'll use the concepts presented here for the rest of your life. However, depending on the type of backend development you're doing, you may need to study additional related sections. For example, if you're doing socket programming, you might need to focus more on the L4 layer. Think of this course as a primer for learning keywords.

Reference material) Complete roadmap for Zero Seconds lectures

Q. Are there any programs I need to install in advance?

It is recommended to install wireshark and node.js.

    I highly recommend this lecture because even majors can review what they have already studied and learn a lot about overall networks and HTTP!

      I listened carefully! It was great to have concepts that I didn't know or had vague knowledge of organized all at once!

        I've only listened to session 1, but I'm satisfied. A few years ago, when I was studying for my final exam, I first learned about the OSI 7-layer system. I remember memorizing it without understanding what it meant and just memorizing it. Until recently, I knew about the 7-layer system, but I didn't have a clear understanding of each layer. But now I understand it for the first time. It took a long time to study while searching and organizing the terms that were mentioned here and there, but I'm quite satisfied. I'm a first-year non-major developer, and I'm always envious of majors because I thought it was difficult even after reading CS books or lectures. But after taking this lecture, I realized that I can understand it too and that I should study harder. Thank you. 😍

            I came across ZeroCho's roadmap video on YouTube by chance and decided to take the course, and it was really beneficial content. It wasn't the type of lecture where someone stiffly reads from a script, but rather explained in a comfortable conversational tone, which I liked. It was less boring. Anyway, if I had studied on my own, I think I would have had to struggle for quite a long time to figure out what's important and what's less important, but it was really great that you taught mainly the things that are essential to know in actual work. I could quickly acquire essential CS knowledge, so it was a complete win. I think I was able to save a lot of precious time. It was so interesting to learn how the internet network that I used daily without thinking was designed, and from a non-major's perspective, if you dream of becoming a developer, HTTP seemed like essential common knowledge you really need to know. If you listen to this lecture two or three times repeatedly, I don't think you'll be looked down upon for not knowing the basics of networking just because you're a non-major. Phew. Anyway, personally, I think it would be good for non-majors to definitely listen to it once, so I strongly recommend it. Oh, for those who are confused about what to study, I think it would be good to first look up ZeroCho's roadmap video on YouTube like I did. It was very helpful for me to set direction as well.
