Purpose and Entry Point

This is a static, curated CS-fundamentals repository for placement preparation, not an executable application. The primary navigation and catalog entry point is README.md, which links users to subject folders and individual learning assets.

Content Architecture

The repository is organized by interview-relevant CS domains. Each domain is a self-contained content boundary holding notes, cheatsheets, tutorials, and interview-question material:

• Computer-Network/

• DBMS-and-SQL/

• DSA/

• OOPs/

• Operating-System/

• Software-Engineering/

• System-Design/

Core-Fundamentals Study Track

The main technical study flow is subject-first: users enter a domain folder, consume concept/reference material, then use associated interview or practice assets.

• Networking: Computer-Network/CN-Roadmap.md, Computer-Network/Computer-Network-Notes-for-Placements-and-GATE.pdf, Computer-Network/Networking-Interview-Questions.pdf

• Databases: DBMS-and-SQL/DBMS-Notes.pdf, DBMS-and-SQL/Complete-SQL-Cheatsheet.pdf, DBMS-and-SQL/LeetCode-SQL.pdf

• Algorithms: DSA/DSA-Resource.pdf, DSA/Striver-SDE-Sheet-Solution.pdf, DSA/Top-50-DSA-Interview-Questions.docx

• Operating systems: Operating-System/Operating-System-Part-1.pdf, Operating-System/Operating-System-Part-2.pdf, Operating-System/Operating-System-Interview-Questions.pdf

Language and Design Specialization

OOP material is separated by implementation language while retaining a shared interview-preparation layer. This lets readers select language-specific conceptual references without changing repository structure:

OOPs/OOPS-Concepts-in-Java.pdf, OOPs/Python-OOP.pdf, OOPs/OOP-in-CPP.pdf.

System-level design material is similarly grouped as reference, condensed review, and interview practice in System-Design/System-Design-Notes.pdf, System-Design/System-Design-Cheatsheet.md, and System-Design/System-Design-Interview-Questions.pdf.

Interview-Preparation Layer

Cross-domain preparation assets sit at the repository root and complement the technical folders. They support coding practice, behavioral interviews, job discovery, and application drafting:

LeetCode-Problems.pdf, HR-Interview-Questions.pdf, List-of-Companies-Hiring-Freshers-Offcampus.md, Cover-Letter-Template.docx, and 25-Job-Interview-Preparation-Prompts.md.

Documentation and Content Boundaries

Markdown files provide the accessible index and selected roadmaps/cheatsheets; PDFs and DOCX files are the primary immutable content payloads. Some subject folders contain local README.md files—such as DBMS-and-SQL/README.md, DSA/README.md, and Operating-System/README.md—which can serve as domain-local entry points. There is no source runtime, build system, database, API, deployment infrastructure, or external service integration represented in the tree; users consume documents directly through a repository browser or local file viewer.
