Why we use the VCS(VERSION CONTROL SYSTEM)?

 Tracking Changes: It records changes to files over time, enabling developers to see who changed what and when.

 Collaboration: Multiple people can work on the same project simultaneously without overwriting each other’s work.

 Branching and Merging: Developers can create separate branches for different features or experiments and later merge them into the main project.

 Version History: It keeps a history of all changes, making it easy to revert to previous versions if needed.

 Conflict Resolution: Helps manage and resolve conflicts when multiple developers make changes to the same file.

 Backup and Recovery: Acts as a backup for the project.
