Tor Network Functionality: The Tor network is designed to protect user anonymity by routing traffic through a series of relays (nodes). This obfuscates the source of the traffic and makes it difficult to trace.

SOCKS Proxy: Tor primarily functions as a SOCKS proxy to facilitate this anonymization. Applications configured to use Tor's SOCKS proxy will have their traffic routed through the Tor network.

Default Ports:

9050: The standard SOCKS port used by standalone Tor installations.

9150: The typical SOCKS port for the Tor Browser Bundle, a self-contained package with Tor and a pre-configured browser.
