When you are trying to checkout a git branch, HEAD points to the top of that branch. The HEAD in Git is the current branch on which you're working on. It may also be used from there to travel to distinct points of history and function.Changes from the last point visited will be used to create changes.It is used to refer to the branch recently committed.head in a phrase: HEAD in all caps is a reference or commit that you are accessing in your repository, while a 'head' without caps is “head” that you are not viewing. There could be a variety of heads in a repository, but just one HEAD. For example, 'main' is a 'head' since a branch is a reference to it. It may refer to all of the 'heads' in a repository while 'head' is written in lowercase. In lowercase, you can see 'head' printed. Note: to signify this status, we have used all capital letters.

In the repository, HEAD points to the starting point of the current branch at all times. HEAD is a reference to the last commit in the current check-out branch. Whenever you check out a branch or create a new branch, Git HEAD transfers it. In simple terms, you can say Git HEAD is the current branch. When you use the git checkout branch, HEAD points out the last commit. There are many git commands that you can use to manage your branches in git.
