Why is TOP necessary and what does it mean?

Through the use of TOR technology, you may hide who you are when using the internet. The Onion Router, or onion router, is referred to by the abbreviation TOR. Thor, currently known as the Tor Project, was initially a US military project but was soon made accessible to sponsors. This technology's basic idea is to offer security and anonymity over the Internet, where most users lack mutual trust. With this particular network, data is encrypted as it passes through many computers, and each computer's IP address is dynamically altered, giving you an encrypted data path in the end.
