Country Code
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 number ...

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 ...

Mobile Country Codes
The ITU-T Recommendation E.212 defines mobile country codes (MCC) as well as mobile network codes (MNC). The mobile country code consists of three decimal digits and the mobile network code consists of two or three decimal digits (for example: MNC of 001 is not the same as MNC of 01). The first digit of the mobile country code identifies the geographic region as follows (the digits 1 and 8 are not used): * 0: Test networks * 2: Europe * 3: North America and the Caribbean * 4: Asia and the Middle East * 5: Australia and Oceania * 6: Africa * 7: South and Central America * 9: Worldwide (Satellite, Air—aboard aircraft, Maritime—aboard ships, Antarctica) An MCC is used in combination with an MNC (a combination known as an "MCC/MNC tuple") to uniquely identify a mobile network operator (carrier) using the GSM (including GSM-R), UMTS, LTE, and 5G public land mobile networks. Some but not all CDMA, iDEN, and satellite mobile networks are identified with an MCC/MNC tuple ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyrillic
The Cyrillic script ( ) is a writing system used for various languages across Eurasia. It is the designated national script in various Slavic, Turkic, Mongolic, Uralic, Caucasian and Iranic-speaking countries in Southeastern Europe, Eastern Europe, the Caucasus, Central Asia, North Asia, and East Asia, and used by many other minority languages. , around 250 million people in Eurasia use Cyrillic as the official script for their national languages, with Russia accounting for about half of them. With the accession of Bulgaria to the European Union on 1 January 2007, Cyrillic became the third official script of the European Union, following the Latin and Greek alphabets. The Early Cyrillic alphabet was developed during the 9th century AD at the Preslav Literary School in the First Bulgarian Empire during the reign of Tsar Simeon I the Great, probably by the disciples of the two Byzantine brothers Cyril and Methodius, who had previously created the Gl ...

GOST 7
GOST () refers to a set of international technical standards maintained by the Euro-Asian Council for Standardization, Metrology and Certification (EASC), a regional standards organization operating under the auspices of the Commonwealth of Independent States (CIS). All sorts of regulated standards are included, with examples ranging from charting rules for design documentation to recipes and nutritional facts of Soviet-era brand names. The latter have become generic, but may only be sold under the label if the technical standard is followed, or renamed if they are reformulated. History GOST standards were originally developed by the government of the Soviet Union as part of its national standardization strategy. The word GOST (Russian: ) is an acronym for ''gosudarstvennyy standart'' (Russian: '), which means ''government standard''. The history of national standards in the USSR can be traced back to 1925, when a government agency, later named Gosstandart, was establish ...

NIST
The National Institute of Standards and Technology (NIST) is an agency of the United States Department of Commerce whose mission is to promote American innovation and industrial competitiveness. NIST's activities are organized into physical science laboratory programs that include nanoscale science and technology, engineering, information technology, neutron research, material measurement, and physical measurement. From 1901 to 1988, the agency was named the National Bureau of Standards. History Background The Articles of Confederation, ratified by the colonies in 1781, provided: The United States in Congress assembled shall also have the sole and exclusive right and power of regulating the alloy and value of coin struck by their own authority, or by that of the respective states—fixing the standards of weights and measures throughout the United States. Article 1, section 8, of the Constitution of the United States, ratified in 1789, granted these powers to the new Co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

FIPS 10-4
The Federal Information Processing Standard, FIPS 10-4 standard, ''Countries, Dependencies, Areas of Special Sovereignty, and Their Principal Administrative Divisions'', was a list of two-letter country codes that were used by the U.S. Government for geographical data processing in many publications, such as the ''The World Factbook, CIA World Factbook''. The standard was also known as DAFIF 0413 ed 7 Amdt. No. 3 (November 2003) and as DIA 65-18 (Defense Intelligence Agency, 1994, "Geopolitical Data Elements and Related Features"). The FIPS 10-4 codes are similar to (but sometimes incompatible with) the ISO 3166-1 alpha-2 country codes. The standard also includes codes for the top-level subdivision of the countries, similar to but usually incompatible with the ISO 3166-2 standard. History On September 2, 2008, FIPS 10-4 was one of ten standards withdrawn by National Institute of Standards and Technology, NIST as a Federal Information Processing Standard.

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.

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.
