Every commit, and indeed every version of every file, is assigned an ID number
The ID number is a 160-bit number derived from the object's contents
Later on we'll see how, and why this is important
Git jargon: the ID number is called the object's hash or sometimes SHA
(The name of the hash-calculating algorithm is "SHA1")
You can always refer to an object by its ID number
