That's what git calls the "working copy" and from git's perspective it is no more that a device for the user to make the handling of the "real" repository, which lives in the .git directory next to your code, more intuitive.

Besides the working copy users usually interact with the "porcellain"-commands with their repository; read "user interface outside of the wall". These are your git commit, git checkout, git rebase, etc. But they are merely a façade!
