Country Codes
A country code is a short alphanumeric identification code for countries and dependent areas. Its primary use is in data processing and communications. Several identification systems have been developed. The term ''country code'' frequently refers to ISO 3166-1 alpha-2, as well as the telephone country code, which is embodied in the E.164 recommendation by the International Telecommunication Union (ITU). ISO 3166-1 The standard ISO 3166-1 defines short identification codes for most countries and dependent areas: *ISO 3166-1 alpha-2: two-letter code *ISO 3166-1 alpha-3: three-letter code * ISO 3166-1 numeric: three-digit code The two-letter codes are used as the basis for other codes and applications, for example, *for ISO 4217 currency codes *with deviations, for country code top-level domain names (ccTLDs) on the Internet: list of Internet TLDs. Other applications are defined in ISO 3166-1 alpha-2. ITU Telephone country codes Telephone country codes are telephone numb ...

ISO 3166-1 Alpha-2
ISO 3166-1 alpha-2 codes are two-letter country codes defined in ISO 3166-1, part of the ISO 3166 standard published by the International Organization for Standardization (ISO), to represent countries, dependent territories, and special areas of geographical interest. They are the most widely used of the country codes published by ISO (the others being alpha-3 and numeric), and are used most prominently for the Internet's country code top-level domains (with a few exceptions). They were first included as part of the ISO 3166 standard in its first edition in 1974. Uses and applications The ISO 3166-1 alpha-2 codes are used in different environments and are also part of other standards. In some cases they are not perfectly implemented. Perfect implementations The ISO 3166-1 alpha-2 codes are used in the following standards: Imperfect implementations Starting in 1985, ISO 3166-1 alpha-2 codes have been used in the Domain Name System as country code top-level domains ...

ISO 3166-1
ISO 3166-1 (''Codes for the representation of names of countries and their subdivisions – Part 1: Country code'') is a standard defining codes for the names of countries, dependent territories, and special areas of geographical interest. It is the first part of the ISO 3166 standard published by the International Organization for Standardization. It defines three sets of country codes: * ISO 3166-1 alpha-2 – two-letter country codes which are used most prominently for the Internet's country code top-level domains (with a few exceptions). * ISO 3166-1 alpha-3 – three-letter country codes which allow a better visual association between the codes and the country names than the alpha-2 codes. * ISO 3166-1 numeric – three-digit country codes which are identical to those developed and maintained by the United Nations Statistics Division, with the advantage of script (writing system) independence, and hence useful for people or systems using non-Latin scripts. The alphabetic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ISO 3166-1 Alpha-3
ISO 3166-1 alpha-3 codes are three-letter country codes defined in ISO 3166-1, part of the ISO 3166 standard published by the International Organization for Standardization (ISO), to represent countries, dependent territories, and special areas of geographical interest. They allow a better visual association between the codes and the country names than the two-letter alpha-2 codes (the third set of codes is numeric and hence offers no visual association). They were first included as part of the ISO 3166 standard in its first edition in 1974. Uses and applications The ISO 3166-1 alpha-3 codes are used most prominently in ISO/ IEC 7501-1 for machine-readable passports, as standardized by the International Civil Aviation Organization, with a number of additional codes for special passports; some of these codes are currently reserved and not used at the present stage in ISO 3166-1.

ISO 3166-1 Numeric
ISO 3166-1 numeric (or numeric-3) codes are three-digit country codes defined in ISO 3166-1, part of the ISO 3166 standard published by the International Organization for Standardization (ISO), to represent countries, dependent territories, and special areas of geographical interest. They are similar to the three-digit country codes developed and maintained by the United Nations Statistics Division, from which they originate in its UN M.49 standard. They were first included as part of the ISO 3166 standard in its second edition in 1981, but they were released by the United Nations Statistics Division since as early as 1970. An advantage of numeric codes over alphabetic codes is script (writing system) independence. The ISO 3166-1 alphabetic codes ( alpha-2 and alpha-3) use letters from the 26-letter English alphabet and are suitable for languages based on the Latin alphabet. For people and systems using non-Latin scripts (such as Arabic or Japanese), the English alphabet may be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Data Processing
Data processing is the collection and manipulation of digital data to produce meaningful information. Data processing is a form of ''information processing'', which is the modification (processing) of information in any manner detectable by an observer.Data processing is distinct from '' word processing'', which is manipulation of text specifically rather than data generally. Functions Data processing may involve various processes, including: * Validation – Ensuring that supplied data is correct and relevant. * Sorting – "arranging items in some sequence and/or in different sets." * Summarization (statistical) or (automatic) – reducing detailed data to its main points. * Aggregation – combining multiple pieces of data. * Analysis – the "collection, organization An organization or organisation (English in the Commonwealth of Nations, Commonwealth English; American and British English spelling differences#-ise, -ize (-isation, -izat ...

Federal Information Processing Standard
The Federal Information Processing Standards (FIPS) of the United States are a set of publicly announced standards that the National Institute of Standards and Technology (NIST) has developed for use in computer systems of non-military United States government agencies and contractors. FIPS standards establish requirements for ensuring computer security and interoperability, and are intended for cases in which suitable industry standards do not already exist. Many FIPS specifications are modified versions of standards the technical communities use, such as the American National Standards Institute (ANSI), the Institute of Electrical and Electronics Engineers (IEEE), and the International Organization for Standardization (ISO). Specific areas of FIPS standardization The U.S. government has developed various FIPS specifications to standardize a number of topics including: * Codes, e.g., FIPS county codes or codes to indicate weather conditions or emergency indications. In 1994, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amateur Radio
Amateur radio, also known as ham radio, is the use of the radio frequency radio spectrum, spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, and emergency, emergency communications. The term ''"radio amateur"'' is used to specify ''"a duly authorized person interested in radioelectric practice with a purely personal aim and without wikt:pecuniary, pecuniary interest"'' (either direct monetary or other similar reward); and to differentiate it from commercial broadcasting, public safety (police and fire), or two-way radio professional services (maritime, aviation, taxis, etc.). The amateur radio service (''amateur service'' and ''amateur-satellite service'') is established by the International Telecommunication Union (ITU) through their recommended radio regulations. National governments regulate technical and operational characteristics of transmissions and issue individual station li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of FIPS Country Codes
This is a list of FIPS 10-4 country codes for ''Countries, Dependencies, Areas of Special Sovereignty, and Their Principal Administrative Divisions''. The two-letter country codes were used by the US government for geographical data processing in many publications, such as the CIA World Factbook. The standard is also known as DAFIF 0413 ed 7 Amdt. No. 3 (Nov 2003) and as DIA 65-18 (Defense Intelligence Agency, 1994, "Geopolitical Data Elements and Related Features"). The FIPS standard includes both the codes for independent countries (similar but often incompatible with the ISO 3166-1 alpha-2 standard) and the codes for top-level subdivision of the countries (similar to but usually incompatible with the ISO 3166-2 standard). The ISO 3166 codes are used by the United Nations and for Internet top-level country code domains. Non-sovereign entities are in italics. On September 2, 2008, FIPS 10-4 was one of ten standards withdrawn by NIST as a Federal Information Processing Standard ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
