Tor
Tor is the name of several related and interconnected projects, all centered around providing you with anonymity and privacy online. In the simplest sense, Tor is the name of a free software project that protects your privacy online by bouncing your communications around a distributed network of computers (called "relays") run by volunteers all around the world. This network of relays is called the Tor Network.
The Tor Browser Bundle is a web browser (forked from Firefox) that is pre-configured to protect your anonymity online. It includes related projects like Vidalia, TorButton and others that make browsing anonymously simple. The Tor Browser Bundle is the only recommended way to use Tor.
Finally, The Tor Project is a 501(c)(3) non-profit (charity) organization that maintains and develops the Tor software and related projects.
