AI Tech DNA Series: Core Computer Fundamentals from an AI Perspective is an introductory course designed to help you understand the basic concepts of computers needed in the AI era in the easiest way possible. It explains fundamental principles such as CPU, memory, storage, networks, and data structures by connecting them to real-life analogies and AI perspectives, building a solid foundation to advance into Python, AI, security, and cloud.

Experience 90% of Digital Circuit Design hires had! Gain semiconductor product understanding + practical experience & specs + employment leverage tips through [Computer Architecture (CPU / SRAM / CACHE / DRAM / NAND) + SoC Protocol Design (FIFO / AMBA / Serial communication) projects most frequently used by current Samsung Electronics employees in practice]!

We will explain the core computer architecture and operating principles that SW developers need to know in an easy-to-understand manner through illustrations.

Have you ever had a hard time because you didn't understand IT infrastructure (server, network, storage, etc.) technology? Do you want to understand how IT infrastructure is structured and what technologies are applied? This is the only lecture in Korea that explains the various technologies that make up IT infrastructure!

A course that helps you understand core computer architecture concepts and practice explaining them verbally in interviews

You can learn about the basic structure and operating principles of computer hardware, design methods, and OS, and acquire the knowledge necessary to create good programs.

A course that helps you understand core operating system concepts and practice explaining them verbally in interviews

This course does not teach fashion. It structurally interprets how retail works. Sales are not merely the result of selling; they are the outcome of a system where KPI design, goal management, inventory turnover, workforce operations, and the strategic gap between headquarters and the field are all interconnected. Stagnant sales and organizational conflicts are not issues of emotion, but issues of design. Through the interpretation of sales structures, the principles of KPI operation, the design of operational frameworks, and the analysis of strategic conflicts, this course redefines retail from the perspective of data and structure. It is a process of moving beyond simply understanding retail to gaining the vision to design it.

This lecture explains the principles of computer architecture, which is the knowledge underlying programming, for non-majors. The goal of the lecture is to become familiar with the principles of program operation.

CS knowledge lectures on design patterns, networks, operating systems, databases, etc. from the author of the #1 book in Korea, "CS Major Knowledge Notes for Interviews"! Covers all the concepts needed for CS interviews and the latest past questions!

I will transform the Engineer Information Processing written exam (Subjects 1–5) from a "test you solve by memorizing" into a "test where you connect clarified points directly to your score." This is an ultra-compressed lecture designed to help you grasp the entire flow within 3 days. It extracts only the core concepts repeated in past exams, structured to be understood even if viewed right before the test. The course is designed for short-term success by clearly distinguishing between frequently confusing concepts, trap points in multiple-choice options, and what needs to be memorized versus what only needs to be understood. "I'm short on time, but the scope is too broad." "I feel like I know the material when reading the book, but I keep getting the questions wrong." This lecture is for students facing these exact challenges.

The author of "Learning Linux Kernel Structure and Principles Through Debugging" clearly explains the basic debugging features and methods of the latest Linux kernel (v6.1), most widely used in system software.

Now I can analyze the Linux kernel too! The easiest kernel lecture among Linux kernel lectures.

You can learn the basics of AWS and Terraform usage simultaneously. You can become familiar with them through hands-on practice.

Have you learned C++ and Java separately but felt confused about why they were designed differently? This course compares both languages simultaneously, helping you fully understand object-oriented structure, memory, and operational principles. Beyond simple syntax, you will gain a deep understanding through hands-on practice of: ✔ Compilation structures ✔ Memory model differences ✔ Internal workings of inheritance and polymorphism ✔ Virtual tables and JVM architecture Additionally, we provide a 'Python-based code comparison auto-generator tool' to help you visually understand the conversion structure between C++ and Java. We will elevate your skills from simply "using" object-oriented programming to a level where you can "design and explain" it.

Through this course, students will learn the overall concepts and flow of databases and operating systems.

The author of "Learning Linux Kernel Structure and Principles through Debugging" properly explains the core concepts of 'workqueue' in the latest Linux kernel (v6.1), which is most widely used in system software.
