A conflict occurs when two branches have made **different changes to the same line(s)** of the same file, and Git cannot automatically determine which version.

A branch in Git is a **lightweight movable pointer** to a commit. Creating a branch costs nothing — it is just a 41-byte file containing a SHA. When you commit.

`git merge` integrates the history of one branch into another. It finds the **common ancestor** of the two branches and combines their changes, creating a new.

git rebase moves or replays a sequence of commits onto a new base, rewriting history to produce a clean linear commit graph.
