As a software engineer, learning a version control tool is one of the best things you can have in your bag.

Right off the bat, I want to clear this doubt many people have!

Is Git and GitHub the same?

The answer is NO! In order to explain it in simpler terms,

Git is a version control system that lets you manage and keep track of your source code history.
GitHub is a cloud based hosting service that lets you manage Git Repositories.
