Computer Science Essentials: Algorithms and Core Concepts

Whether you are a self-taught programmer, a bootcamp graduate, or looking to transition into tech, lacking a formal computer science background can feel like a major hurdle. Understanding the core principles of computation, data structures, and algorithms is key to writing efficient code and passing technical interviews. This text-only course bridges the gap between writing basic code and thinking like a computer scientist. You will build a strong theoretical foundation and learn how to apply these concepts to real-world software development challenges. In this course, you will learn to: 1. Understand foundational computer science terminology, binary logic, and memory management. 2. Analyze algorithm efficiency using Big O notation to write highly performant code. 3. Implement and use essential data structures such as arrays, linked lists, stacks, queues, and hash tables. 4. Explore advanced data structures including trees, graphs, and modern vector databases. 5. Apply fundamental sorting and searching algorithms to solve complex computational problems. 6. Learn modern software engineering patterns, including type safety, basic testing principles, and clean system design. The course begins with essential terminology and binary representation before moving on to data structures, algorithmic complexity, and modern architectural principles. Each concept is explained through clear text and practical code snippets that illustrate the theory in action. This course is designed for beginner developers, self-taught programmers, and anyone looking to build a structured understanding of computer science fundamentals from scratch.
