black box1. The device in an airplane that records flight audio and data. Once the black box is recovered from the wreckage, it will give us more insight into what caused the crash.2. Any sort of system or device with inner workings that are difficult to understand. Does anyone outside of the IT department really understand how this black box works?See also: black, boxa black box You can call a process or system a black box when you know that it produces a particular result but you do not understand how it works. What steroids do is currently something of a black box. The firm's investment success lies in its black box of formulas which identify trends. Note: In an electronic or computer system, a black box is a self-contained part. You can understand its function without knowing anything about how it works. See also: black, boxblack box an automatic apparatus, the internal operations of which are mysterious to non-experts. Black does not refer to the colour of the device but to the arcane nature of its functions. Originally Royal Air Force slang for a navigational instrument in an aircraft, the phrase is now used in aviation specifically to refer to the flight recorder.See also: black, boxblack box
black box1. a self-contained unit in an electronic or computer system whose circuitry need not be known to understand its function 2. an informal name for flight recorderBlack Box (in Russian, chernyi iashchik), an object of study whose internal structure either is unknown or is too complex for any conclusions about the behavior of the object to be drawn on the basis of the properties of the object’s elements or on the basis of the structure of the connections between the elements. In Russian, the term chernyi iashchik is also used to refer to the method of studying such objects. The black-box method is used in cases where an outside observer knows only the input to an object and the object’s response; in such cases, the processes occurring within the object are unknown. The study of a multiterminal network whose internal circuitry is unknown provides a very simple example of the use of the black-box method. By observing the behavior of such an object for a sufficiently long time and, if necessary, by carrying out active experiments on the object (that is, by changing the input in some specific manner), a level of knowledge about the properties of the object may be achieved such that changes in the object’s behavior in response to any given input may be predicted. However, no matter how thoroughly the behavior of a black box is studied, an unambiguous conclusion about the internal structure of the object cannot be reached, since the same behavior may be characteristic of different objects. The black-box method is widely used to solve problems in the modeling of controlled systems—for example, in the study of integrated systems—especially in cases where the behavior rather than the structure of a system is of interest. black box[′blak ‚bäks] (engineering) Any component, usually electronic and having known input and output, that can be readily inserted into or removed from a specific place in a larger system without knowledge of the component's detailed internal structure. black box A typical recording of an earlier version of flight data recorder (FDR). Modern FDRs can record many more parameters. A typical flight data recorder/voice recorder. These are colored orange.i. The generic name given to crash data recorders and voice data recorders. Although called black boxes, they are orange. They can withstand very high temperatures and high impact.
ii. Any unit, usually an electronic or avionic device such as an amplifier, that can be mounted in, or removed from, the aircraft as a single package.black box (jargon)An abstraction of a device or system in which onlyits externally visible behaviour is considered and not itsimplementation or "inner workings".

(2) An electronic device that records airplane flight data. Officially a "flight data recorder," the unit is highly protected and can emit a signal for up to 30 days after a crash, even underwater. First used in the late 1950s, Australia was the first country to require them. Dating back to the late 19th century, a "train event recorder" or "on-train monitoring recorder" (OTMR) is the equivalent device in a locomotive.
(3) An electronic device that records driving data in motor vehicles, most notably their speed. Officially an "event data recorder," automotive black boxes were first used in the late 1990s.
(4) Any custom-made electronic device can be called a black box, typically made to solve some interfacing problem. Such devices were named black boxes because they were often housed in plain containers, and their purpose may even be a mystery to the experienced observer. However, yesterday's black boxes sometimes become today's off-the-shelf products. See COTS.

black box1. (Jargon) descriptive of a method of reasoning or studying a problem, in which the methods and procedures, as such, are not described, explained, or perhaps even understood: conclusions relate solely to the empiric relationships observed; 2. in some contexts, the term can mean a piece of apparatus or an experimental animal in which the pharmacologic or toxicologic pathway has not yet been worked out. black box Pathology

Black Box1. Any complex investment strategy or model. In general, a black box involves a computer using complicated formulas to achieve returns in the desired way. Because an investor may not understand the model (and may not be able to do so), a black box can lead to unforeseen problems. See also: Black box syndrome.
2. In Islamic finance, a strategy that allows one to invest funds in a Sharia-compliant way but still link the returns to non-compliant investments. Using a black box is very controversial and some Islamic finance scholars reject it as un-Islamic.AcronymsSeebaseballblack box
