Tor is a free software that enables anonymous communication over the internet. It works by routing your internet traffic through a network of volunteer-operated servers, known as nodes, which helps to conceal your location and usage from surveillance and traffic analysis. This makes it difficult for anyone to track your online activities. Users typically access Tor through the Tor Browser, which is designed to protect privacy while browsing the web. While Tor can be used for legitimate purposes, such as protecting privacy in oppressive regimes, it is also associated with illegal activities due to the anonymity it provides.
