The International Organization for Standardization (ISO) is an independent, non-governmental membership organisation dedicated to the development of voluntary international standards. ISO members represent national standards organisations from 162 countries.
Many of the standards developed by ISO covers issues related to information and communications technologies (ICT), including with regard to the Internet. One of the most well-known example is standard ISO 27001 on information security. Other standards cover issues such as: open systems interconnection, information processing, information systems interoperability, identification cards, communication devices, etc. The ISO 3166 standard for country codes is used by the Internet Corporation for Assigned Names and Numbers (ICANN) as the basis for the allocation of top level domains (ccTLDs) to countries and territories.
Even though maybe less noticed, the work of ISO provides invaluable contributions to the efficiency and functionality of the Internet.
