Overview of Computer Science

Definition: The study of algorithms, data structures, software design, programming languages, and computer systems.
Interdisciplinary Fields: Includes mathematics, engineering, and sometimes psychology and biology.

Key Areas of Computer Science

Algorithms and Data Structures
- Algorithms: Step-by-step procedures for calculations and data processing.
- Data Structures: Ways to organize and store data (e.g., arrays, trees, graphs).
Software Engineering
- Principles of software design, implementation, and maintenance.
- Involves methodologies like Agile and Waterfall.
Computer Systems
- Study of computer architecture, operating systems, and networking.
- Focuses on hardware-software interactions.
Artificial Intelligence (AI)
- Machine learning, natural language processing, computer vision, robotics.
- Focus on creating systems that can perform tasks requiring human intelligence.
Human-Computer Interaction (HCI)
- Design and evaluation of user interfaces.
- Emphasis on user experience and usability.
Database Systems
- Management of data storage, retrieval, and manipulation.
- Concepts include SQL, NoSQL, and data warehouses.
Web Development
- Front-end (user interface) and back-end (server-side) development.
- Technologies include HTML, CSS, JavaScript, and server-side languages like Python and Ruby.

Fundamental Concepts

Programming Languages: Tools for writing code (e.g., Python, Java, C++).
Operating Systems: Software that manages computer hardware and provides services for application software (e.g., Windows, Linux).
Networking: Study of how computers communicate over networks; includes concepts like TCP/IP, LAN, WAN, and the internet.

Emerging Trends
