What is Version Control? Version control is a system that keeps track of changes to files over time. It allows multiple people to collaborate on a project, tracks who changed what and when, and lets you go back to an earlier version of the project if something goes wrong.

What is Version Control Used For? 1: Collaboration 2: Backup and Restore 3: Track changes 4: Experiment safely 5: Deployment

What is Git? Git is a popular version control system. It helps you manage code changes locally (on your own computer).

What is GitHub? GitHub is a cloud-based platform that hosts Git repositories. It’s like Dropbox for code, but with tools for collaboration.
