Tor is a connection-based low-latency (meaning fast) anonymous communication system that
protects TCP (Transmission Control Protocol) streams for Usenet, web browsing, instant
messaging (IM), internet relay chat (IRC), Secure Shell (SSH), etc. In basic language Tor is a socks server that accepts and encrypts data from any program that
is "socksified", meaning set up to communicate with it.
