Visual Studio Git - HEAD & Master branch under remote/origin

Question

I have not created local branch while making changes. I used master branch that gets created locally and made commit & sync changes after modifying few things.

Now, I see there are two branches that got created in remotes/origin, HEAD and master. Initially before doing this commit, I used to see only one ie master branch under remotes/origin. So, want to know ---

1. what is HEAD branch for
2. and whether I can delete it.
3. And, was that created on the server as well.

Answer 1

HEAD is not a branch it is a reference or pointer to the most recent commit in the current branch.
