What you will gain after the course

Understanding Core Concepts of Computer Architecture
The ability to explain things verbally in technical interviews
Practical workbook PDF that prepares you for follow-up questions

🥲 Have you ever had this experience in an interview?

1. Confusing concepts when answering

❓InterviewerWhat are the characteristics of object-oriented programming?
💬 Candidate The SOLID principles. First, S is..(omitted)...
This is a situation where the characteristics of object-oriented programming (abstraction, encapsulation, inheritance, polymorphism) and
object-oriented design principles (SOLID) are confused.
This can give the impression that the fundamental framework of basic concepts is not established.

2. Knowing only What, but unable to explain How / Why

❓Interviewer What are the characteristics of TCP?
💬 Candidate It's a protocol that guarantees reliability.
❓ Interviewer What mechanisms guarantee reliability?
💬 Candidate Uh... well... it makes transmission secure... like...
You only know the superficial definition and are not prepared to explain the principles.
If 3-way handshake, sequence numbers, ACK, retransmission, flow control, and congestion control
are not connected as one flow, you will inevitably get stuck on follow-up questions.

3. Getting stuck on basic questions

❓Interviewer What is HTTP?
💬 Candidate Um... it's for sending and receiving data on the web... something like that...?
It's a very familiar concept, but when you actually try to explain it in one sentence, the words don't come out.
This isn't a lack of knowledge, but rather a lack of experience organizing and articulating it.

Just knowing is not enough. It only becomes true skill when you can articulate it.

1⃣ CS Notes organized specifically for interview preparation

All essential concepts and principles you must review before interviews are compiled and provided as lecture materials.
It's structured to build your fundamentals while allowing you to review it right up until your interview.
It's not just a simple summary, but includes diagrams and easy explanations so that even non-majors can fully understand.

Computer Architecture Lecture Material Example

2⃣ Appendix | Interview Practice Materials Provided

In interviews, the ability to explain clearly is far more important than simply knowing something.
However, organizing and practicing on your own is not easy and can be a tedious task.
At the end of the lecture materials, we've included "answering in one or two sentences" training to reduce the effort of organizing.

Database Course Appendix Example

3⃣ Prepare for follow-up questions with our Technical Interview Practice Workbook PDFincluded

"Will this course alone really be enough for speaking practice?"
After much consideration,
I created a Technical Interview Practice Workbook.
Designed so you can practice speaking as if in a real interview on your own.
You can find detailed information about the workbook structure and how to use it in the workbook introduction video at the beginning of the course.

Operating System Workbook Example

4⃣ A course that keeps growing with a one-time purchase

This course is provided with an unlimited enrollment period.
The content will continue to expand with new explanations, additional examples, and more.
Even if the price increases as content is added, students who have already purchased
can access all content at no additional cost.
It's a CS fundamentals book you can keep coming back to whenever you need it.

1⃣ Download the materials and learn key concepts while watching the lectures.
2⃣ Take notes on important parts to create your own CS interview notebook.
3⃣ Save it on your phone and review briefly whenever you have time.

If you have an interview coming up,
and don't have much time → Use the appendix [Interview Practice] in the course materials to quickly sharpen your interview skills.
If you have time → Complete your speaking practice like a real interview with the Technical Interview Practice Workbook.

⭐️⭐️⭐️⭐️⭐️

1. A lecture that shows how much the author has thought and considered from the student's perspective (seems to consider the learner's flow of understanding)
2. Easy to understand with diverse visual materials and examples
3. When learning knowledge, it mentions and reminds you of previously learned content and connects the knowledge. Knowledge connects and the big picture emerges.
4. The depth of knowledge is not shallow. I'm taking the OS course right after computer architecture, and the synergy is great.
5. Scratches all the itches about "why" & "why it's used".
ps. Sorry to the author, but.. this is a lecture I want to keep to myself.

-'Operating Systems' Course Review

⭐️⭐️⭐️⭐️⭐️

Despite the short lecture duration, I really appreciate how you clearly explain only the important parts. Since it was somewhat theory-focused, I didn't expect SQL queries to be covered, but it was great that you showed examples one by one while teaching basic syntax and how to write queries. After that, the coverage of joins, normalization, transactions, indexes and data optimization, and security was excellent. I haven't tried other paid courses yet, but the last lecture appendix titled "Interview Practice" was great for self-study and practice as it directly showed questions and answers. The lecture duration isn't too long if you focus, so I think I'll go through it multiple times. Thank you

-'Database' Course Review

🖐 Hello! Let me introduce myself! 🙇

As someone from a non-CS background, when I first prepared for a developer job, I only focused on algorithms and coding tests.
I gained some confidence and passed most coding tests, but I kept failing at the next hurdle—technical interviews. What was the problem? It was the lack of CS (Computer Science) knowledge.

I understand the thirst for fundamentals (CS knowledge, programming languages, etc.) better than anyone. I dove into countless resources through self-study and built my own know-how, and now I'm working as a 🧑🏻‍💻 Kakao developer.

Since I was young, I've been more confident than anyone in combining and reorganizing various materials to create 'my own consolidated notes'. This course is that secret notebook containing all that know-how and passion.

This was my first time studying CS, but it was easy to understand and I could feel the concepts I had seen while studying for computer literacy and other computer-related certifications connecting together. I especially like how the interview practice appendix at the end is neatly organized for use during interviews. I think it would be great if you could do one for Python too haha..

Learning Analog Circuits Through Flow, Not Formulas: 6 Steps to Understanding Filters and OP-AMPs [Theory Edition]

tjrgud007264321

The 0s and 1s we talk about, HIGH and LOW, logic gates and flip-flops— they all emerge from the physical event of analog signals crossing a threshold. If so, wouldn't understanding the world before logic— the movements created by current and voltage— be the true beginning of circuit design? This course takes that first step together.
