Version Control Systems (VCS) are crucial for managing changes to source code, documents, or any set of files. They track modifications, allow reverting to previous states, and facilitate collaboration among multiple developers.

Version control, also known as source control, is a system that records changes to a file or set of files over time so that you can recall specific versions later.

• Track Changes: Monitor modifications in your codebase.
• Collaboration: Multiple developers can work on the same project simultaneously.
• Backup: Provides a backup mechanism for your project files.
• Branching & Merging: Allows for experimental development without affecting the main codebase.

There are mainly two types:

• Centralized VCS: Like SVN where there's a single repository for all changes.
• Distributed VCS: Like Git, where each developer has a full copy of the repository.

• Version control is essential for managing code changes effectively.
• It offers benefits like tracking changes, team collaboration, and safe experimentation.
• There are centralized and distributed types of VCS, each serving different needs.
