The file was changed but not staged

The file is untracked

The file is deleted

In 'git status', the term 'modified' indicates that changes have been made to a tracked file since the last commit, but these changes have not yet been added to the staging area. This means the file is still in its current state and needs to be staged before it can be committed.

11. In 'git log', what does the hash represent?

The branch name

A unique identifier for the commit

The author's username
