Fetch_Head is a reference that keeps track of what was fetched from the remote repository.
When you run git fetchthe command, Git downloads the contents of the remote branch you specified. These contents are referred to as commits.
So, Fetch_HEAD will store the SHA_1 of the commit at the tip of the specified branch. As we mentioned before, git pullwill be fetched from the remote and called git merge, which will merge Fetch_HEAD into the tip of the current local branch.

Fetch_Headnot only contain information for a single branch. It will store references to all branches fetched from the remote repository.
For example, if you are checked out in the master branch, you can run git fetch, followed by git merge Fetch_Head. In hindsight, this is the same as git fetchfollowed by .git merge origin/master
Instead of naming things, you'll be referring to any single reference you fetch from the remote repository.
