Version control system
A version control system (VCS) is a tool that keeps track of what has changed in a file and can roll back to a previous state. A simple example of a version control system is the history of changes in Google Docs or Microsoft Word: you can see how the content of the documents changed step by step, and roll back to a previous version if something went wrong. It is also useful when working in teams: you can see exactly who made each change.

A version control system is an important part of the software development process:
- Change tracking: Every change in the code is logged and stored in the history. Developers can easily track who made changes to the project, when, and what changes were made.
- Restore Previous Versions: If something goes wrong or new code causes problems, developers can easily revert to a previous stable version of the project and fix the problems.
- Conflict Management: When multiple developers are working on the same project, conflicts arise when merging changes. The version control system allows you to resolve them and integrate changes into a common code base.
- Collaboration and teamwork: Version control makes it easier for a team to work on the same project and share code. Any developer can make changes to the code and easily synchronize them with the changes made by other project participants.
Git version control system
Git is one of the most popular version control systems, it's hard to find a developer who doesn't use this tool.
Git main features:
Distributed architecture: Each project member has a full copy of the repository. This allows you to work offline and share changes.
Branch and merge functionality: You can create independent branches to work on individual tasks or bug fixes, and then merge them into a common project branch.
Resilience to data corruption: Git was designed for reliability and data protection.
