The term de jure means "according to law" or "in compliance with the law". De jure standards are developed and adopted by national and international standards bodies such as the IEEE, the Internet Engineering Task Force (IETF), ANSI
and others. Unlike de jure standards, de facto standards are those that have been created by industry and are widely used. Such a de facto standard may later be declared a de jure standard by a standards body. An example of this is the TCP protocol, which was later standardized by the IETF.
