What is "tor"

Tor \Tor\, n. [AS. torr; cf. Gael. torr. Cf. Tower.]

1. A tower; a turret. [R.]
   --Ray.

2. High-pointed hill; a rocky pinnacle. [Prov. Eng.]

   A rolling range of dreary moors, unbroken by tor or tree.
   --C. Kingsley.

"high, rocky hill," Old English torr "rock, crag;" said to be a different word than torr "tower." Obviously cognate with Gaelic torr "lofty hill, mound," Old Welsh twrr "heap, pile;" and perhaps ultimately with Latin turris "high structure" (see tower (n.)). But sources disagree on whether the Celts borrowed it from the Anglo-Saxons or the other way round.

Etymology 1 a. (alternative form of tore lang=en nodot=1) ("hard, difficult; strong; rich"). Etymology 2

n. 1 A craggy outcrop of rock on the summit of a hill. 2 (context South-West England English) A hill. 3 (context UK dialect English) A tower; a turret.

1. n. a prominent rock or pile of rocks on a hill

2. a high rocky hill

A tor, which is also known by geomorphologists as either a castle koppie or kopje, is a large, free-standing rock outcrop that rises abruptly from the surrounding smooth and gentle slopes of a rounded hill summit or ridge crest. In the South West of England, the term is commonly also used for the hills themselves – particularly the high points of Dartmoor in Devon and Bodmin Moor in Cornwall.

Tor is a genus of cyprinid fish commonly known as mahseers.

Tor, TOR or ToR may refer to:

Tor is an American comics series, created by Joe Kubert and Norman Maurer in the story 1,000,000 Years Ago! (Sept. 1953), published by St. John Publications. The series' protagonist, Tor, is a prehistoric cave man who has fantasy adventures set in a realistically drawn setting. The original series only ran for five issues and ended in 1954. However, "Tor" was revived by DC Comics in June 1975 for six issues. In June 1993 Marvel Comics released new adventures of Tor.

Tor research station is a Norwegian Antarctic research station in Queen Maud Land, in the easternmost part of Princess Martha Coast at Svarthamaren Mountain, established in 1993. It is located 1625 metres above sea level, about 200 km from the coast. It is smaller than the other Norwegian station, Troll, and a summer-only station.

Tor is free software for enabling anonymous communication. The name is derived from an acronym for the original software project name "The Onion Router". Tor directs Internet traffic through a free, worldwide, volunteer network consisting of more than seven thousand relays to conceal a user's location and usage from anyone conducting network surveillance or traffic analysis. Using Tor makes it more difficult for Internet activity to be traced back to the user: this includes "visits to Web sites, online posts, instant messages, and other communication forms". Tor's use is intended to protect the personal privacy of users, as well as their freedom and ability to conduct confidential communication by keeping their Internet activities from being monitored.

Onion routing is implemented by encryption in the application layer of a communication protocol stack, nested like the layers of an onion. Tor encrypts the data, including the destination IP address, multiple times and sends it through a virtual circuit comprising successive, randomly selected Tor relays. Each relay decrypts a layer of encryption to reveal only the next relay in the circuit in order to pass the remaining encrypted data on to it. The final relay decrypts the innermost layer of encryption and sends the original data to its destination without revealing, or even knowing, the source IP address. Because the routing of the communication is partly concealed at every hop in the Tor circuit, this method eliminates any single point at which the communicating peers can be determined through network surveillance that relies upon knowing its source and destination.

An adversary might try to de-anonymize the user by some means. One way this may be achieved is by exploiting vulnerable software on the user's computer. The NSA had a technique that targets a vulnerability - which they codenamed "EgotisticalGiraffe" - in an outdated Firefox browser version at one time bundled with the Tor package, and in general, targets Tor users for close monitoring under its XKeyscore program. Attacks against Tor are an active area of academic research, which is welcomed by the Tor Project itself.
