This course covers the fundamental concepts of operating systems, one of the core subjects in computer science. Operating systems are essential software for efficient resource management and providing user environments in computer systems, and through this course, learners can systematically understand how operating systems work and what components they consist of. Additionally, by learning the structures and functions of various operating systems, students will master the detailed operating principles of operating systems such as processes, memory management, file systems, and disk management, and can solidly build the foundational knowledge necessary for actual development and system utilization. Through this course, learners will gain a comprehensive understanding of operating systems and will be able to have confidence in advanced computer science learning and practical applications.

I have been working in the IT field for 20 years in development and construction. I would like to be a good guide for those who are entering or starting out in the development field.

Bestseller 『Study Computer Architecture + Operating Systems on Your Own』 author's free lecture. A collection of computer architecture and operating systems books that developers must know.

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!

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

This course explains IT terminology and system structures frequently used in the workplace in a way that even non-majors can understand at once. It is designed to help you understand the flow of corporate IT structures—from servers and databases to APIs, security, and the cloud—rather than just learning individual terms. We will help you build foundational IT skills that are immediately applicable to your work, so you will no longer be stuck due to technical jargon in IT meetings and tasks.

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

Welcome to AWS? First Time? Let's learn together, from the basics of modern web systems to cloud deployment. It's not just simple AWS usage or following along with code; you can learn deeply how even difficult CS concepts are applied in the Cloud!

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.

This is a C programming course for those who wish to pursue a path as a professional developer rather than just a hobbyist. I recommend this to those who are willing to learn through bitter and rigorous study to reach a sweet destination!

This lecture is expected to help students build a foundation in computer architecture.

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

You need to have a solid understanding of the basic principles of operating systems to understand advanced programming techniques. This lecture is a specialist-level lecture on the dinosaur book, which can be called the bible of operating systems.

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.
