Core Operating System Principles for Aspiring Developers: From Processes to File Systems

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.

This course puts an end to operational vulnerabilities in Linux servers caused by incorrect permissions. Completely master file and directory permission control based on real-world practical standards.

Many people use Docker, but few understand its underlying principles. Without understanding these principles, you can only rely on searching for answers when problems arise, rather than solving them yourself. The essence of Docker lies in the operating system. This course is not a superficial overview of memorizing a few commands; it delves deep into the inner workings of the operating system that makes up Docker. Once the internal structure becomes visible, Docker is no longer difficult.

We'll teach you essential Windows System programming skills for developing games and applications for Windows.

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 is Part 1 of a roadmap course that neatly organizes, in a short amount of time, the essential computer science (CS) knowledge you need to excel at development and data. This course has also been used for years as an in-house course at top companies in Korea. Based on 20 years of experience in the field, ranging from systems software to web and app development and data science, this course systematically and thoroughly covers the core concepts you need to excel at development and data—while keeping them easy to understand.

A course where you understand core operating system concepts and train to explain them verbally for interviews.

This course is a “Core Practical Linux” course designed not only for those encountering Linux for the first time, but also for those looking to enhance their Linux skills in practice. It covers the essential fundamentals of Linux, along with only the most frequently used and indispensable features from the perspective of a backend developer in the field.
