Difference between HEAD and master

Question

What is the difference between the HEAD and master in Git?

I did a clone of a project on GitHub and want to push my changes to the remote.

Answer 1

The simple answer is that HEAD is a pointer/label to the most recent commit of the branch you are currently on. master is the default branch created when you initialized a git repository (e.g. git init).

You can delete the master branch (e.g. git branch -D master). You cannot delete the HEAD pointer.
