• origin refers to the source repository from where it was cloned.
• HEAD is a reference to the last commit in the currently checked-out branch.
• Staged and index both are same
• Unstaged changes exist in our Working Directory, but Git hasn’t recorded them into its version history yet.
• Staged changes are a lot like unstaged changes, except that they’ve been marked to be committed the next time you run git commit
