A De Facto Standard – or ad hoc standard – is based on common practices that are well established. De facto standards for format, language, or protocol, have wide general acceptance although they are not formally recognized by a standards developer. Common de facto standards include the arrangement of keys on a typewriter or keyboard (QWERTY keyboard) and the MS-DOS computer operating system.
