Nominal Number
Nominal numbers are numerals used as labels to Unique identifier, identify items uniquely. Importantly, the actual values of the numbers which these numerals represent are less relevant, as they do not indicate quantity, rank, or any other measurement. Labelling referees Smith and Kumar as referees "1" and "2" is a use of nominal numbers. Any set of numbers (a subset of the natural numbers) will be consistent labels as long as a ''distinct'' number is uniquely used for each distinct term which needs to be labelled. Nonetheless, sequences of integers may naturally be used as the simplest way to begin labelling; for example, 1, 2, 3, and so on. Definition The term "nominal number" may be quite recent and of limited use. It appears to have originated in school textbooks derived from the statistical term "nominal data", defined as data indicating "...merely statements of qualitative category of membership." This usage comes from the sense of wikt:nominal, nominal as "name". Mathemat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Economics
Economics () is a behavioral science that studies the Production (economics), production, distribution (economics), distribution, and Consumption (economics), consumption of goods and services.

National Identification Number
A national identification number or national identity number is used by the governments of many countries as a means of uniquely identifying their citizens or residents for the purposes of work, taxation, government benefits, health care, banking and other governmentally-related functions. They allow authorities to use a unique identifier which can be linked to a database, reducing the risk of misidentification of a person. They are often stated on national identity documents of citizens. The ways in which such a system is implemented vary among countries, but in most cases citizens are issued an identification number upon reaching legal age, or when they are born. Non-citizens may be issued such numbers when they enter the country, or when granted a temporary or permanent residence permit. Such numbers may also locally referred to as a national insurance number, social security number, tax identification number, JMBG/EMBG or by their local name. Some countries issued such ...

Car Model
The model of a car is its design, in the context of the manufacturer's range or series of cars. Different models, variants are distinguishable by technology, components, underpinnings, and/or style and appearance. The methods used to categorise cars into models differ significantly between manufacturers. Frequently, several different body variants are offered, depending on market demand; and when completing their 'production lifespan', sufficiently successful models are usually followed by a new 'generation' of that model. The name of a model (range or series) is almost always trademarked, so that competing manufacturers cannot also use it (unless the owner permits it, for an agreed licence fee). A popular model can have a significantly valuable brand, brand name, and manufacturers often take great care in fostering and maintaining the brand image of the models bearing the name, both in terms of key model characteristics, as well as the targeted market, and the expected or desi ...

North American Numbering Plan
The North American Numbering Plan (NANP) is an integrated telephone numbering plan for twenty-five regions in twenty countries, primarily in North America and the Caribbean. This group is historically known as World Zone 1, World Numbering Zone 1 and has the telephone country code, country code ''1''. Some North American countries, most notably Telephone numbers in Mexico, Mexico, do not participate in the NANP. The concepts of the NANP were devised originally during the 1940s by the American Telephone and Telegraph Company (AT&T) for the Bell System and the independent telephone companies in North America in Operator Toll Dialing. The first task was to unify the diverse local telephone numbering plans that had been established during the preceding decades, with the goal to speed call completion times and decrease the costs for long-distance calling, by reducing manual labor by switchboard operators. Eventually, it prepared the continent for direct-dialing of long-distance calls ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ITU-T
The International Telecommunication Union Telecommunication Standardization Sector (ITU-T) is one of the three Sectors (branches) of the International Telecommunication Union (ITU). It is responsible for coordinating Standardization, standards for telecommunications and Information Communication Technology, such as X.509 for cybersecurity, Y.3172 and Y.3173 for machine learning, and H.264/MPEG-4 AVC for video compression, between its Member States, Private Sector Members, and Academia Members. The World Telecommunication Standardization Assembly (WTSA), the sector's governing conference, convenes every four years. ITU-T has a permanent Secretariat (administrative office), secretariat called the Telecommunication Standardization Bureau (TSB), which is based at the ITU headquarters in Geneva, Switzerland. The current director of the TSB is Seizo Onoe (of Japan), whose 4-year term commenced on 1 January 2023. Seizo Onoe succeeded Chaesub Lee of South Korea, who was director from 1 J ...

Telephone Numbering Plan
A telephone numbering plan is a type of numbering scheme used in telecommunication to assign telephone numbers to subscriber telephones or other telephony endpoints. Telephone numbers are the addresses of participants in a telephone network, reachable by a system of destination code routing. Telephone numbering plans are defined world-wide, as well as within each of the administrative regions of the public switched telephone network (PSTN), and in private telephone networks. In public numbering systems, geographic location typically plays a role in the sequence of numbers assigned to each telephone subscriber. Many numbering plan administrators subdivide their territory of service into geographic regions designated by a prefix, often called an area code or city code, which is a set of digits forming the most-significant part of the dialing sequence to reach a telephone subscriber. Within such regions designated by area codes, locally unique telephone number are assigned based on lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telephone Number
A telephone number is the address of a Telecommunications, telecommunication endpoint, such as a telephone, in a telephone network, such as the public switched telephone network (PSTN). A telephone number typically consists of a Number, sequence of digits, but historically letters were also used in connection with telephone exchange names. Telephone numbers facilitate the switching and routing of telephone call, calls using a system of destination code routing. Telephone numbers are entered or dialed by a calling party on the originating telephone set, which transmits the sequence of digits in the process of signaling to a telephone exchange. The exchange completes the call either to another locally connected subscriber or via the PSTN to the called party. Telephone numbers are assigned within the framework of a national or regional telephone numbering plan to subscribers by telephone service operators, which may be commercial entities, state-controlled administrations, or ot ...

Postal Code
A postal code (also known locally in various English-speaking countries throughout the world as a postcode, post code, PIN or ZIP Code) is a series of letters or numerical digit, digits or both, sometimes including spaces or punctuation, included in a postal address for the purpose of sorting mail. the Universal Postal Union lists 160 countries which require the use of a postal code. Although postal codes are usually assigned to geographical areas, special codes are sometimes assigned to individual addresses or to institutions that receive large volumes of mail, such as government agencies and large commercial companies. One example is the French Cedex (France), CEDEX system. Terms There are a number of synonyms for postal code; some are country-specific: * Codice di Avviamento Postale, CAP: The standard term in Italy; CAP is an acronym for ('postal expedition code'). * Código de Endereçamento Postal, CEP: The standard term in Brazil; CEP is an acronym for ('postal add ...

ABA Routing Transit Number
In the United States, an ABA routing transit number (ABA RTN) is a nine-digit code printed on the bottom of cheque, checks to identify the financial institution on which it was drawn. The American Bankers Association (ABA) developed the system in 1910 to facilitate the sorting, bundling, and delivering of paper checks to the drawer's (check writer's) bank for debit to the drawer's account. Newer electronic payment methods continue to rely on ABA RTNs to identify the paying bank or other financial institution. The Federal Reserve Bank uses ABA RTNs in processing Fedwire funds transfers. The ACH Network also uses ABA RTNs in processing direct deposits, bill payments, and other automated money transfers. Management Since 1911, the American Bankers Association has partnered with a series of registrars, currently Accuity, to manage the ABA routing number system. Accuity is the Official Routing Number Registrar and is responsible for assigning ABA RTNs and managing the ABA RTN system. ...

International Bank Account Number
The International Bank Account Number (IBAN) is an internationally agreed upon system of identifying bank accounts across national borders to facilitate the communication and processing of cross border transactions with a reduced risk of transcription errors. An IBAN uniquely identifies the account of a customer at a financial institution. It was originally adopted by the European Committee for Banking Standards (ECBS) and since 1997 as the international standard ISO 13616 under the International Organization for Standardization (ISO). The current version is ISO 13616:2020, which indicates the Society for Worldwide Interbank Financial Telecommunication (SWIFT) as the formal registrar. Initially developed to facilitate payments within the European Union, it has been implemented by most European countries and numerous countries in other parts of the world, mainly in the Middle East and the Caribbean. By July 2024, 88 countries were using the IBAN numbering system. The IBAN consi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sort Code
Sort codes are the domestic bank codes used to route money transfers between financial institutions in the United Kingdom, and formerly in Ireland. They are six-digit hierarchical numerical addresses that specify clearing banks, clearing systems, regions, large financial institutions, groups of financial institutions and ultimately resolve to individual branches. In the UK they continue to be used to route transactions domestically within clearance organizations and to identify accounts, while in Ireland (a founder member of the Euro) they have been deprecated and replaced by the Single European Payment Area (SEPA) systems and infrastructure. Sort codes for Northern Ireland branches of banks (codes beginning with a '9') were registered with the Irish Payment Services Organization (IPSO) for both Northern Ireland and the Republic of Ireland. These codes are used in the British clearing system and historically in the Irish system. The sort code is usually formatted as three pairs ...

Bank Code
A bank code is a code assigned by a central bank, a bank supervisory body or a Bankers Association in a country to all its licensed member banks or financial institutions. The rules vary to a great extent between the countries. Also the name of bank codes varies. In some countries the bank codes can be viewed over the internet, but mostly in the local language. The (national) bank codes differ from the international Bank Identifier Code (BIC/ISO 9362, a normalized code - also known as Business Identifier Code, Bank International Code and SWIFT code). Those countries which use International Bank Account Numbers (IBAN) have mostly integrated the bank code into the prefix of specifying IBAN account numbers. The bank codes also differ from the Bank card code (CSC). The term "bank code" is sometimes (inappropriately) used by merchants to refer to the Card Security Code printed on the back of a credit card.
