After reading the post (and many others), I think I'm starting to get it:

-You have a directory/folder (data store) where all of the files are stored

-Some files (blobs) are data files

-Some files (trees) are hierarchy - they specify the structure of the data (blob) files, and how they connect to each other (like a database)

-Some files (commits) are snapshots (think VM snapshot) of the arrangement of the blobs on the trees (data file structure)

-Some files (tags) hold metadata about the data files (blobs)

And it's all tied together by SHAs (GUIDs) which are just a random number that's so huge it's probably unique.

You can use URLs to point to any of these files, so you can tie together files from different locations at once.
