Git is a distributed version control system that tracks changes in source code during software development. GitHub is a web-based platform that provides hosting for Git repositories, offering collaborative features like issue tracking and pull requests. Developers use Git to manage code history, revert to previous versions, and branch for new features, while GitHub facilitates teamwork and code review. This process is crucial for maintaining code integrity and enabling efficient collaboration on projects. For instance, a team can use Git and GitHub to manage updates to a web application's codebase, ensuring everyone works from the latest version and changes are properly integrated. Unlike centralized version control systems, Git's distributed nature allows for offline work and faster operations. Understanding Git and GitHub is foundational for many IT roles and appears in domains related to software development and DevOps on certifications like AWS SAA.
