The Tor network was engineered to protect personal privacy and to give users freedom from Internet monitoring.
"TOR" is short for the original name,“The Onion Router”, and it refers to the many layers of routing - over seven thousand! These layers are called onion routing, and it relies on volunteers around the world who use their computer as nodes.
When you visit a website on Tor, your information doesn't go directly to that server. Instead, it’s passed through a number of randomly assigned nodes before reaching its destination server. The other thing to note is that the packets of information sent over the Internet are obscured in Tor, wrapped in layers of packets. This ensures that no node knows the destination server, but only the next node it is to be passed to.
