What is the default status of an untouched file in GIT?

Question

I was studying git. They mention three states of files:
modified, staged and commited.
Now I am not able to understand one thing. Suppose I am working with 5 files in my current working directory. I edit 3 files and mark them staged and commit them to store the next snapshot in the database. What was the status of the two untouched files. Do I have to mark all files as commited?
NOTE I DON'T HAVE ANY KNOWLEDGE ABOUT GIT. I HAVE JUST STUDIED AN INTRODUCTION.

No need. As the files stay in the same state even if you 'git add *' them git just ignores the unchanged ones.
Git just creates kind of pointers to states of objects, if one stays, the pointer doesn't need updating either.
