Token Ring
Token Ring network IBM hermaphroditic connector with locking clip. Screen contacts are prominently visible, gold-plated signal contacts less so. Token Ring is a computer networking technology used to build local area networks. It was introduced by IBM in 1984, and standardized in 1989 as IEEE 802.5. It uses a special three-byte frame called a ''token'' that is passed around a logical ''ring'' of workstations or servers. This token passing is a channel access method providing fair access for all stations, and eliminating the collisions of contention-based access methods. Token Ring was a successful technology, particularly in corporate environments, but was gradually eclipsed by the later versions of Ethernet. History A wide range of different local area network technologies were developed in the early 1970s, of which one, the Cambridge Ring, had demonstrated the potential of a token passing ring topology, and many teams worldwide began working on their own implementations. ...

Tokenization (data Security)
Tokenization, when applied to data security, is the process of substituting a sensitive data element with a non-sensitive equivalent, referred to as a token, that has no intrinsic or exploitable meaning or value. The token is a reference (i.e. identifier) that maps back to the sensitive data through a tokenization system. The mapping from original data to a token uses methods that render tokens infeasible to reverse in the absence of the tokenization system, for example using tokens created from random numbers. A one-way cryptographic function is used to convert the original data into tokens, making it difficult to recreate the original data without obtaining entry to the tokenization system's resources. To deliver such services, the system maintains a vault database of tokens that are connected to the corresponding sensitive data. Protecting the system vault is vital to the system, and improved processes must be put in place to offer database integrity and physical security. ...

The Tokens
The Tokens were an American doo-wop band and record production company group from Brooklyn, New York City. The group has had four top 40 hits on the ''Billboard'' Hot 100, all in the 1960s, their biggest being the chart-topping 1961 hit single, "The Lion Sleeps Tonight". "The Lion Sleeps Tonight" borrowed heavily from the 1939 song "Mbube" by South African singer Solomon Linda. They are also known for having included at first Neil Sedaka, who later pursued a solo career. History The band was formed in 1955 at Abraham Lincoln High School in Brooklyn, New York, and was known first as the Linc-Tones, a name inspired by the President of the United States' surname. Original members were Neil Sedaka, Hank Medress, Eddie Rabkin, and Cynthia Zolotin, however Rabkin was replaced in 1956 by Jay Siegel. In the same year the band recorded its first single, "While I Dream", with Sedaka on lead vocals: the song was a local hit in New York; Sedaka and Howard Greenfield wrote much of the gr ...

Token (rapper)
Benjamin David Goldberg (born September 24, 1998), known professionally as Token, is an American rapper from Salem, Massachusetts. He has appeared on Sway’s Friday's Fire Cipher and has a catalog of videos on YouTube. His most recent video, "Ain't It Funny", uses a sample of his son playing the recorder. Early life Ben Goldberg was born and raised in Marblehead, Massachusetts. He was introduced to hip-hop music at age six by Justin Brown. His mother, Leslie Goldberg, described him as having incidents of "explosive anger". In his younger years, Goldberg was often suspended from school for yelling at his teachers and fighting with other students. Goldberg was eventually diagnosed with depression and anxiety. Additionally, he had difficulty in understanding expressive language, being diagnosed with a language disability as a result. As a child, Goldberg suffered from obesity, weighing nearly 140 pounds in the fourth grade. He began running on the treadmill after school and l ...

Tokenism
Tokenism is the practice of making only a perfunctory or symbolic effort to be inclusive to members of minority groups, especially by recruiting people from underrepresented groups in order to give the appearance of racial or gender equality within a workplace or educational context. The effort of including a token individual in work or school is usually intended to create the impression of social inclusiveness and diversity (racial, religious, sexual, etc.). History The social concept and the employment practice of ''tokenism'' became understood in the popular culture of the United States in the late 1950s. In the face of racial segregation, tokenism emerged as a solution that though earnest in effort, only acknowledged an issue without actually solving it. In the book ''Why We Can't Wait'' (1964), civil rights activist Martin Luther King Jr. discussed the subject of tokenism, and how it constitutes a minimal acceptance of black people to the mainstream of U.S. society.

Token Money
Token money, or token, is a form of money that has a lesser intrinsic value compared to its face value. Token money is anything that is accepted as money, not due to its intrinsic value but instead because of custom or legal enactment. Token money costs less to produce than its face value. A banknote, e.g. a five-pound note, is token money because despite its value being 5 pounds it only costs significantly less to produce. A gold coin is not considered token money. The Token money system has been adopted in many businesses around the world as an effective way to exchange value between companies and customers. Token money as a system is predominantly used in mobile games, but is also used in the realm of e-commerce. Token money is similar to fiat money which also has little intrinsic value, however they differ in that token money is a limited legal tender. The adoption of token money has improved transaction efficiency, as the practicalty of transacting with sums of gold poses a ...

Exonumia
Exonumia are numismatic items (such as tokens, medals, or scrip) other than coins and paper money. This includes "Good For" tokens, badges, counterstamped coins, elongated coins, encased coins, souvenir medallions, tags, wooden nickels and other similar items. It is related to numismatics (concerned with coins which have been legal tender), and many coin collectors are also exonumists. Besides the above strict definition, others extend it to include non-coins which may or may not be legal tenders such as cheques, credit cards and similar paper. These can also be considered notaphily or scripophily. Etymology The noun ''exonumia'' is derived from two classical roots: ''exo'', meaning "out-of" in Greek, and ''nummus'', meaning "coin" in Latin (from Greek νοῦμμος – ''noummos'', "coin"); thus, "out ideof- he categoryoins". Usually, the term "exonumia" is applied to these objects in the United States, while the equivalent British term is paranumismatica. The words ''ex ...

Token Coin
In numismatics, token coins or trade tokens are coin-like objects used instead of coins. The field of token coins is part of exonumia and token coins are token money. Their denomination is shown or implied by size, color or shape. They are often made of cheaper metals like copper, pewter, aluminium, brass and tin, or non-metals like bakelite, leather and porcelain. A legal tender coin is issued by a governmental authority and is freely exchangeable for goods. A token coin is less useful and issued by a private entity. Trade or barter Coin-like objects from the Roman Empire called have been interpreted as an early form of token. Their functions are not documented, but they appear to have been brothel tokens or possibly gaming tokens. Medieval English monasteries issued tokens to pay for services from outsiders. These tokens circulated in nearby villages, where they were called "Abbot's money". Also, counters called jetons were used as small change without official blessing. ...

Security Token
A security token is a peripheral device used to gain access to an electronically restricted resource. The token is used in addition to or in place of a password. It acts like an electronic key to access something. Examples of security tokens include wireless keycards used to open locked doors, or in the case of a customer trying to access their bank account online, bank-provided tokens can prove that the customer is who they claim to be. Some security tokens may store cryptographic keys that may be used to generate a digital signature, or biometric data, such as fingerprint details. Some may also store passwords. Some designs incorporate tamper resistant packaging, while others may include small keypads to allow entry of a PIN or a simple button to start a generating routine with some display capability to show a generated key number. Connected tokens utilize a variety of interfaces including USB, near-field communication (NFC), radio-frequency identification (RFID), or Bluetoo ...

Lexical Token
In computer science, lexical analysis, lexing or tokenization is the process of converting a sequence of characters (such as in a computer program or web page) into a sequence of ''lexical tokens'' (strings with an assigned and thus identified meaning). A program that performs lexical analysis may be termed a ''lexer'', ''tokenizer'', or ''scanner'', although ''scanner'' is also a term for the first stage of a lexer. A lexer is generally combined with a parser, which together analyze the syntax of programming languages, web pages, and so forth. Applications A lexer forms the first phase of a compiler frontend in modern processing. Analysis generally occurs in one pass. In older languages such as ALGOL, the initial stage was instead line reconstruction, which performed unstropping and removed whitespace and comments (and had scannerless parsers, with no separate lexer). These steps are now done as part of the lexer. Lexers and parsers are most often used for compilers, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Token (railway Signalling)
In railway signalling, a token is a physical object which a train driver is required to have or see before entering onto a particular section of single track. The token is clearly endorsed with the names of the section it belongs to. A token system is more commonly used for single lines because of the greater risk of collision in the event of a mistake being made by a signaller or traincrew, than on double lines. Principle The operation of a bidirectional single track line has the hazard of two trains colliding. The simplest way to prevent such collisions is to have only one train in the section at any given time. Such a system is known as "one-engine-in-steam” (OES) or “one-train working" (OTW). This system is used on some branches of rail networks, and on heritage railways. The main disadvantage is that it restricts the number of train movements that can be made. For a larger railway system, it becomes exceptionally limiting in the level of operations that it allows, wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tolkien Black
Tolkien Black (originally known as Token Williams and Token Black) is a fictional character in the adult animated television series ''South Park''. He was originally voiced by Trey Parker, later changed to series art director, storyboard artist and producer Adrien Beard. The original name "Token" was a play on the politically-correct ideas of tokenism, but in " The Big Fix" it was retconned that his name was "Tolkien", not "Token", despite his Facebook profile using the name "Token" in "You Have 0 Friends" and him writing his name the same way in “ Raising the Bar”. Biography Tolkien attends South Park Elementary, who is a third-then fourth-grade student of Mr. Garrison's class, who was replaced by Mrs. Nelson in season 19. He was originally the only African American student attending the school until Nichole Daniels was introduced in " Cartman Finds Love". Residing in South Park, he is the only child of Linda and Steve Black, who were originally the only African American ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
