Origin of collocationClassical Latin collocatio
Two words that often go together, such as light sleeper or early riser are an example of collocation.
- The act of collocating or the state of being collocated.
- An arrangement or juxtaposition of words or other elements, especially those that commonly co-occur, as rancid butter, bosom buddy, or dead serious.
- (uncountable) The grouping or juxtaposition of things, especially words or sounds.
- (countable) Such a specific grouping.
- (linguistics, translation studies) The statistically significant collocation of particular words in a language.
- (mathematics) A method of determining coefficients in an expansion so as to nullify the values of an ordinary differential equation at prescribed points.
- (computing) A service allowing multiple customers to locate network, server, and storage gear, connect them to a variety of telecommunications and network service providers, with a minimum of cost and complexity.
1605. From Latin collocātiōnem < collocāre. Compare French collocation.
The technical sense in linguistics was established 1951, although it may have been used this way earlier.
collocation - Computer Definition
- A physical arrangement in which things are placed close together.
- In telecommunications, referring to the placement of the equipment of a competitive local exchange carrier (CLEC) or Internet service provider (ISP) in the incumbent LEC's (ILEC's) central office (CO). A collocation arrangement generally requires that the ILEC provide a separately area, such as a cage, for the CLEC or ISP to secure its termination equipment, switches, routers, and other equipment. See also CLEC, CO, ILEC, and ISP.
One of the most important yet misunderstood services in the telecommunications industry. It combines elements of civil engineering, electrical engineering, facility management, real estate, and standard bits and bytes. By definition, collocation is the leasing of available space and power within a facility in order to operate telecommunications equipment. A network without collocation facilities—rack counts, square footage, amps, and conduits—is like a car without seats: Although the engine is in place, the car is not fully functional. Carriers back in the 1980s needed and present-day carriers continue to need somewhere to house their equipment so that they can use and manipulate the bandwidth being purchased.
Before American Telephone & Telegraph’s breakup in 1984, the Bell companies rarely considered carrier requests to collocate equipment. Seeing a competitive advantage in the marketplace, however, IXCs (long-haul carriers) and CAPs (local carriers) began leasing space for carrier equipment, giving rise to a new industry product: collocation or collocation facilities.
Today, collocation is not usually offered as a stand-alone product but is a value-added component often made available to carriers purchasing capacity on the network. In short, collocation helps to facilitate the buying and utilization of a carrier’s bandwidth by clients. The main service that collocations provide is up time by providing redundant power supplies with backup generators and redundant links to the Internet. In the end, the client gains by having reduced bandwidth service costs.
