Version control is a system that records changes to a file or set of files over time so that you can recall specific versions later. It allows multiple individuals to collaborate on a project simultaneously, tracking who made what changes and when. This process is fundamental for managing software development, document creation, and any project involving iterative modifications. In practice, developers commit their changes to a central repository, enabling rollbacks to previous states if errors are introduced or new features are required. Understanding version control is crucial for maintaining project integrity, facilitating teamwork, and ensuring a reliable audit trail. For instance, Git is a widely used distributed version control system that powers platforms like GitHub and GitLab. It differs from simple file backups by providing a detailed history of modifications and enabling branching for parallel development. Version control concepts are frequently tested in project management certifications like PMP and CAPM, as well as in IT infrastructure and cloud exams.
