What is Version Control?

Version Control is a system that tracks changes in files over time, allowing multiple people to collaborate, revert to previous versions, and manage updates efficiently.

What is Git?

Git is a distributed version control system used to track changes in files and collaborate with others on software projects. It helps developers keep track of code history, revert to previous versions, and collaborate seamlessly.
