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.

Database concepts most frequently encountered in interviews and practical work, This introductory course is organized flow- and diagram-centrically. From SQL basic syntax to normalization, transactions, indexes, sharding/partitioning, and security, It explains seemingly complex DB concepts, structurally linking them with real-world examples. Finally, an interview practice chapter is included, So you can confidently answer questions like "What is a transaction?" and "When are indexes used?".

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 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.

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.
