Apache Subversion (often abbreviated SVN; hereinafter, the Software) is open-source version control system (VCS). The Software tracks files and directories, and the changes made to them, over time. This allows you to recover older versions of your data or examine the history of how your data changed. The Software can operate across networks, which allows it to be used by people on different computers. At some level, the ability for various people to modify and manage the same set of data from their respective locations fosters collaboration. Progress can occur more quickly without a single conduit through which all modifications must occur. And because the work is versioned, you need not fear that quality is the trade-off for losing that conduit—if some incorrect change is made to the data, you are able to undo the changes made.
