Solutions: ISO: International Standards Organization. The International Standards Organization develops standards for international and national data communications. The U.S. representative to the ISO is the American National Standards Institute, or ANSI. In the early 1970's, the ISO developed a standard model of a datacommunications system and called it the Open System Interconnection model. Consisting of seven layers, it describes what happens when a terminal talks to a computer or one computer talks to another. This model was designed to facilitate creating a system in which equipment from different vendors can communicate. The other data communication models are IBM's System Network Architecture (SNA) and Digital Equipment's DEC Network Architecture (DNA), which both predated the OSI model.
