Verziókezelésrl

Verziókezelésrl, or 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. This allows you to revert files back to a previous state, compare changes, see who made changes, and more. It is a fundamental tool in software development, but also applicable to any project where files are modified repeatedly.

The core idea behind version control is the repository, a central storage location for all project files and their history. When you make changes, you commit them to the repository. Each commit represents a snapshot of your project at a particular point in time. This history allows you to track the evolution of your work, identify when bugs were introduced, and understand the reasoning behind specific modifications.

Distributed version control systems (DVCS) are the most common type today. In a DVCS, every developer has a full copy of the repository, including its history. This means you can commit locally without being connected to a central server and collaborate with others by sharing changesets. Popular DVCS include Git, Mercurial, and Subversion.

Benefits of version control include improved collaboration, as it helps manage concurrent work and merge changes effectively. It also enhances accountability, providing a clear audit trail of who did what and when. Furthermore, it safeguards against data loss by maintaining a complete history, making it easy to recover previous versions if needed.
