What you will gain after the course

Understanding Core Operating System Concepts
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 foundational concepts are not solidly grasped.

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 safe... like...
You only know the superficial definition and are not prepared to explain the underlying principles.
If the 3-way handshake, sequence numbers, ACK, retransmission, flow control, and congestion control
are not connected as a single 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 concept you're very familiar with, 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 becomes true skill only when you can articulate it.

1⃣ Interview-focused lectures covering only the essentials

I've compiled and organized all the essential concepts and principles you must review before an interview
I've structured it so that while building fundamentals, it can ultimately be used for interview preparation
Rather than simple summaries, I've structured it with diagrams and easy explanations so that even non-majors can fully understand.
You can quickly review key content while understanding why it's important as you learn

2⃣ Appendix [Interview Practice] Included

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 your thoughts

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.
You can practice speaking as if in a real interview even 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.

4⃣ A course that keeps growing with a single 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
This is a CS fundamentals guide 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, connecting the knowledge. Knowledge connects and the big picture emerges.
4. The depth of knowledge is not shallow. I'm taking OS right after Computer Architecture, and the synergy is great.
5. Scratches the itch of "why" & "why is it used" questions.
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.

What is an Operating System
- Definition and functions of operating systems,
  Hardware managed by the operating system
Hardware Execution Process
- Kernel mode and user mode, interrupts,
  system calls,
  Program execution process
Process
- Process context and state,
  Process Control Block,
  Threads and Multithreading
CPU Scheduling
- CPU scheduling performance metrics and various
  CPU scheduling algorithms,
  Context switching
Process Synchronization and Deadlock
- Race Condition, Critical Section,
  Semaphore, Mutex,
  Deadlock
Memory Management & Virtual Memory
- RAM, MMU,
  Paging,
  Segmentation, Virtual Memory, Page Replacement Algorithms
File System & Disk Management
- File protection, file allocation methods,
  Hard disk data components,
  Disk Scheduling Techniques
[Appendix] Interview Practice
- Review key concepts once more in Q&A format

3⃣ Complete Dissection of 'Deadlock' with Code and Diagrams! In-Depth Analysis of Core OS Mechanisms

It covers in depth process synchronization techniques such as semaphores and mutexes, as well as the conditions for deadlock occurrence and resolution strategies, through actual code examples and resource allocation graph diagrams.
Additionally, from virtual memory operating principles such as paging and segmentation to disk I/O scheduling and file allocation methods, we provide in-depth analysis of complex algorithms and mechanisms with visual materials to deliver essential knowledge needed for interviews and practical work.

Who is this course right for?

A non-CS major who feels lost because they're studying CS for the first time
A computer science major who needs to organize CS concepts before a technical interview
A job seeker preparing for a career change who has limited time before a technical interview

Need to know before starting?

It's even better if you take the [Computer Architecture](free) course from this series first!
