You don't need to know this, by the way. You can totally just think of git as simply storing a copy of your entire repo every time you make a commit. This is one part of git that actually is a good abstraction.
Of course it is fun to know this but it won't help you understand git really, and please don't tell people who are just learning git. Just say git makes a copy of the whole project every time you commit.
