• Local Repository Structure: The local Git repository has three components: 1.Working Directory: The actual files reside here. 2.Index: The area used for staging. 3.Head: Points to the most recent commit

• Saving Changes All files in a checked out (or working) copy of a project file are either in a tracked or untracked state.

Tracked

Tracked files can be modified, unmodified, or staged; they were part of the most recent file snapshot.

Untracked

Untracked files were not in the last snapshot and do not currently reside in the staging area.

After cloning a repository, files have tracked status and are unmodified because they have been checked out but not edited.
