Tor works by sending your traffic through three random servers (also known as relays) in the Tor network. The last relay in the circuit (the “exit relay”) then sends the traffic out onto the public Internet. The image above illustrates a user browsing to different websites over Tor.

How does the Tor router work?
The Tor browser works by using a technology known as onion routing. The onion router is a peer-to-peer (P2P) overlay network that enables users to browse the internet anonymously. Onion routing uses multiple layers of encryption to conceal both the source and destination of information sent over the network.
How does Tor actually work?
The Tor Browser hides your IP address and browsing activity by redirecting web traffic through a series of different routers known as nodes. Because Tor hides browsing activity and blocks tracking, it's used by whistleblowers, journalists, and others who want to protect their privacy online.
How does Tor build a circuit?
Forming a circuit
A Tor circuit is made up of a guard node, a middle node, and an exit node. The client starts the circuit formation process by contacting the node it has chosen as its guard node. The client and guard node negotiate a TLS session, and the client asks the guard node to help it initialize a Tor circuit.
What is the difference between Tor and onion routing?
Specifically, Tor is a communication protocol that uses a network of relays to stop others from tracking you. The “onion” metaphor is used to indicate the layers upon layers of encryption applied, rendering it difficult to determine who you are and track your online activities.
