Each time you commit a change, the repository stores a new revision of that overall repository tree, and labels the new tree with a new revision number. Of course, most of the tree is the same as the revision before, except for the parts you changed.

The new revision number is a sequential label that applies to the entire new tree, not just to the files and directories you touched in that revision. However, colloquially, a revision number is used to refer to the change committed in that revision; for example, "the change in r588" ("r588" is shorthand for "revision 588") really means "the difference between repository trees 587 and 588", or put another way, "the change made to tree 587 to produce tree 588".
