[CS 기술면접 4] 말이 트이는 데이터베이스

I've carefully selected only the essential JavaScript core concepts you must know for practical work and interviews, covering everything from scope and execution context to closures, prototypes, asynchronous processing, and module systems in one comprehensive course. Going beyond superficial syntax explanations, this course is structured to help you understand how JavaScript actually works from its fundamental principles. Through examples and visual materials, I explain concepts that seemed difficult in an easy way, aiming for 'understanding that can be expressed in words' that you can directly use in interviews. If you want to systematically organize JavaScript's operating principles, start right now.

How does the Internet work, and how do browsers fetch web pages? A core CS (computer-science) lecture, organizing network concepts along the OSI 7-layer model, to enable self-explanation of this question. Structured for intuitive understanding through diagrams and flow-centric explanations, and it organizes concepts frequently appearing in technical interviews—such as Transport Layer (TCP/UDP), IP Address, NAT, HTTPS—by linking them to actual questions.

This is a core CS (computer-science) lecture that organizes essential data structure concepts, which are required for practical work and interviews, centered around intuitive flow and diagrams. It covers the entire range from arrays and lists to trees, graphs, and heaps, selecting only the key parts. It's designed to help even first-time learners quickly grasp the overall context by explaining concepts in a connected structure rather than a simple enumeration. The slides are structured in an organized note format suitable for review, and are especially recommended for those looking for a final review before an interview or who wish to solidify their basic concepts.

Curated to include only operating system concepts frequently encountered in practice and interviews, this is a core CS (computer-science) lecture, easily explained and organized with a focus on diagrams. It was designed so that even those new to it can grasp the flow and quickly continue their learning. The slides themselves are structured to serve as reviewable summary notes. It's a 'foundational building lecture' that you can return to whenever your fundamentals are shaky.

This course carefully selects only the essential Java core concepts you must know for practical work and interviews, covering everything from object-oriented programming to collections, multithreading, and modern Java all in one comprehensive guide. Beyond basic syntax, we explain advanced concepts that make the difference in interviews through diagrams and examples in an easy-to-understand way, organized with slides for quick review at a glance. If you want to systematically organize Java core concepts, start right now.

This is a core CS (computer-science) lecture that selects only the computer architecture concepts frequently encountered in practice and interviews, explaining and organizing them easily with a focus on diagrams. It was designed so that even those encountering it for the first time can grasp the flow and quickly continue with subsequent learning. The slides themselves are structured to serve as reviewable summary notes. If you want to get a grasp of the computer architecture flow, start right now.
