Git is a distributed version control system that tracks changes to files over time. It allows multiple developers to collaborate on a project simultaneously, managing different versions and merging them efficiently. Git works by recording snapshots of your project at various stages, enabling you to revert to previous states if needed. This capability is crucial for maintaining code integrity, facilitating rollbacks, and understanding project history, significantly reducing development risks. For instance, a web developer can use Git to track changes to website code, easily reverting to an older version if a new update introduces bugs. Unlike centralized systems where a single server holds the entire history, Git stores the full repository history on each developer's machine. You will encounter Git concepts in domains related to software development and IT operations, often appearing in certifications like CompTIA IT Fundamentals.
