✅ Among the series of (1) to (7), (1) Changes in the role of computers, hierarchical structure, abstraction, PC structure ✅ CS101 series lectures - From basic computer theory to the latest practical examples - Provides a wide range of basic knowledge

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!

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.

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.

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.

This is a general computer theory course centered around the same content included in all certification books.

✅ This is an introductory lecture (0) that introduces the entire series of lectures (1) to (7). ✅ CS101 series lectures - From basic computer theory to the latest practical examples - Provides a wide range of basic knowledge

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

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.

This is a C language programming course for those who want to become professional developers rather than hobbyists. I recommend it to those who want to learn by writing and reading and go down a sweet path!

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

Based on learning fundamental concepts of programming and Python, we solve mathematical problems using Python. (Solutions and roots of equations, drawing graphs)

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

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]!

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

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.

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