Any change in a computing system, such as a new feature or new component, is transparent if the system after change adheres to previous external interface as much as possible while changing its internal behaviour. The purpose is to shield from change all systems (or human users) on the other end of the interface. Confusingly, the term refers to overall "invisibility" of the component, it does not refer to "visibility of component's internals" (as in white box or open system). The term "transparent" is widely used in computing marketing in substitution of the term "invisible", since the term "invisible" has a bad connotation (usually seen as something that the user can't see and has no control over) while the term "transparent" has a good connotation (usually associated with not hiding anything). The vast majority of the times, the term "transparent" is used in a misleading way to refer to the actual invisibility of a computing process. Because of this misleading and counter-intuitive definition, modern computer literature tends to prefer use of "" over "transparent".
