"Atomic" in this context means "All or nothing", i.e. when you commit a change set, either all changes are committed, or none. This ensures that the svn repository is always in a consistent state. In certain other version control systems (e.g. Visual Source Safe), commits (or checkins) are not atomic. If there is a network or system failure in the middle of a check-in action (while checking in multiple changed files), your version control database ends up being inconsistent.
