Identify the Tor relay that receives the client's data from the middle relay and sends the data to the destination website's server.

The exit relay is the component of the Tor network responsible for receiving the encrypted data from the middle relay and then forwarding this data to the destination website's server. Essentially, it acts as the final node in the Tor circuit, where the encrypted traffic is decrypted and sent to the intended internet resource.

This means that when a user accesses a website through Tor, their data passes through various relays to conceal the user's identity and location. The entry relay is the first point of contact with the Tor network, and the middle relay assists in continuing the secure, anonymous journey, but it is the exit relay that directly interacts with the external internet, making it critical for establishing the connection with the desired destination server.

The role of the exit relay is significant because it can see the data that is being sent to the destination server (though it still cannot know the original sender's IP address), and this introduces potential privacy concerns for the user if they are sending unencrypted data. Understanding this structure is essential for recognizing how Tor protects anonymity while navigating through the internet.
