Definition: Version control is the management of changes to code or files over time. It allows developers to track modifications and collaborate effectively.

Tools: Some popular version control systems are:

• Git: A distributed version control system commonly used with platforms like GitHub.
• SVN: A centralized version control system.

Definition: Agile is a project management and software development methodology that emphasizes iterative development, collaboration, and flexibility.

Key Principles:

• Iterative Development: Projects are completed in small, manageable chunks, with each iteration delivering a working product.
• Collaboration: Stakeholders, including customers and team members, work closely together throughout the project.

Definition: Refactoring is the process of restructuring existing code without changing its external behavior, often to improve code readability, efficiency, or maintainability.

Benefits:

• Improves code quality and maintainability.
• Reduces technical debt.
