Core Topics Covered in CS50 Harvard
CS50 provides a broad yet deep introduction to computer science fundamentals.
1. Computational Thinking
Students learn how to break problems into smaller components, identify patterns, and design step-by-step solutions.
This mindset is foundational for all programming and technical disciplines.
2. Programming in C
CS50 begins with the C programming language, which helps students understand:
- Memory management
- Data types
- Pointers
- Low-level computing concepts
Starting with C gives learners a strong technical foundation that makes learning other languages easier.
3. Algorithms and Data Structures
Students explore:
- Searching algorithms
- Sorting techniques
- Time and space complexity
- Efficiency trade-offs
These concepts help learners understand why some solutions perform better than others.
4. Python Programming
After mastering foundational concepts, students transition to Python, a high-level language known for readability and versatility.
Python is used to demonstrate how abstracted languages simplify development while relying on the same underlying principles.
5. Web Development
CS50 introduces basic web technologies, including:
- HTML
- CSS
- JavaScript
Students learn how websites work and how front-end and back-end components interact.
6. Databases and SQL
The course covers database fundamentals, including:
- Data storage
- Queries
- Relational databases
