Reading from http://git-scm.com/book/en/v2/Getting-Started-Git-Basics
I get the following:
Question: Could you please take a look at the following to make sure I have it right:
a. When commit is issued for File A for the first time, a snapshot of File A is saved locally as Version 2.
(Q_a: Is this accurate?)
b. At Version 3 if no changes made to File A but commit is issued, a link is saved to the previous File A at Version 2.
c. All these file snapshots or links are on the local computer?
(Q_c: Are each of these snapshots a complete file to that point or they only contain the changes?)
d. These version could be accessed by other team members.
(Q_d: If they are on a user_1 computer, how the other users get access to it?)
I am continuing to read this link but want to make sure I have it down up to this point.
