Tor is a free and open-source software application that is designed to help users maintain their anonymity and privacy while browsing the internet. It works by routing users’ web traffic through a network of relays, which are run by volunteers all around the world. This helps to conceal a user’s location and usage from anyone who might be observing their network traffic. It is used by many users on the dark web, which is a part of the internet that is not indexed by search engines and is typically only accessible through specialized software such as Tor. The dark web is often used to facilitate criminal activities, but it is also home to many legitimate services, such as social networks and forums.
