Verzióellenrzési

Verzióellenrzési, which translates to "version control" in English, is a system that records changes to a file or set of files over time so that you can recall specific versions later. This allows you to revert to a previous state of the files if, for instance, a new version contains bugs or you lose data. It is a fundamental tool in software development but also applicable to any project where multiple iterations and tracking changes are important.

The primary purpose of version control is to manage modifications to documents, code, or other data. It helps prevent data loss and facilitates collaboration by enabling multiple individuals to work on the same project concurrently without overwriting each other's work. When conflicts arise, version control systems provide mechanisms to resolve them.

Common version control systems include Git, Subversion (SVN), and Mercurial. Git is currently the most widely used distributed version control system. These systems typically operate by creating a repository, a central or distributed storage location for project files and their history. Users can then "commit" their changes to the repository, creating new versions or "revisions." Features like branching allow developers to work on new features or bug fixes in isolation without affecting the main project, and later merge their changes back. Rollbacks are also a standard function, allowing users to revert to a specific past version of the project.
