In science, computing, and engineering, a black box is a device, system or object which can be viewed in terms of its inputs and outputs or transfer characteristics , without any knowledge of its internal workings. Its implementation is "opaque" black. Almost anything might be referred to as a black box: a transistor , an engine , an algorithm , the human brain , an institution or government. The usual representation of this black box system is a data flow diagram centered in the box. The opposite of a black box is a system where the inner components or logic are available for inspection, which is most commonly referred to as a white box sometimes also known as a "clear box" or a "glass box" . The modern meaning of the term "black box" seems to have entered the English language around In electronic circuit theory the process of network synthesis from transfer functions , which led to electronic circuits being regarded as "black boxes" characterized by their response to signals applied to their ports , can be traced to Wilhelm Cauer who published his ideas in their most developed form in In cybernetics , a full treatment was given by Ross Ashby in

A black box model, or more specifically a black box financial model, is a catch-all term used to describe a computer program designed to transform various data into useful investment strategies. In science, computing, and engineering, a black box is a device, system, or object which can be viewed in terms of its inputs and outputs, without any knowledge of its internal workings. The opposite of a black box is a system where the inner components or logic are available for inspection, which is most commonly referred to as a white box which can also come be called a "clear box" or a "glass box".
Black Box is an Italian house music group popular in the late s and early s. The members of the group included a trio made up of a club DJ Daniele Davoli , a classically trained clarinet teacher Valerio Semplici , and a keyboard and electronic music "wiz" Mirko Limoni. The group created an image for Black Box using French fashion model Katrin Quinol on their album and single cover art as the supposed lead singer in all their music videos. The song was often credited by their other alias, Groove Groove Melody. In mid, the group released the maxi-single "Airport 89" under the name Wood Allen. The single peaked at number 99 on the UK Singles chart.
