manishkumar8312/CS-Fundamentals ? reverse-engineered prompt

Build me a clean, well organized study repository for computer science fundamentals that helps B.Tech CSE students and anyone preparing for interviews or exams. I want separate sections for DSA, Operating Systems, DBMS, Computer Networks, OOP, Theory of Computation, and Computer Organization, with easy to follow chapter style notes in markdown. Make the main README feel like a proper landing page with short descriptions, clear links to each topic, and a simple structure that makes it easy to jump into any subject.

Please keep the content focused on concepts, revision, and interview prep, not too verbose, but still useful enough to study from. If helpful, add a polished banner or basic visuals so the repo looks good on GitHub. Organize everything so it is simple to browse and maintain, and make sure the topic names and links are consistent throughout. If you need to look up current docs online for any formatting details, go ahead.
