The smallest independent unit of meaning of a program as defined either by a parser or a lexical analyzer. IBM. In C++, there are five kinds of tokens: identifiers, keywords, literals, operators, and other separators.
A symbol defined by a lexer. We try to use this term to mean the set of terminal symbols defined by the lexer. This is a subset of the complete set of terminal symbols. An identifier is a token, but a keyword is not, because the keyword is classified as an identifier by the lexer.
A sequence of bits (symbol of authority) that is passed successively along a transmission medium from one device to another to indicate the device that is temporarily in control of the transmission medium. Each device can acquire and use the token to control the medium.
The smallest lexical unit in a program. The Java compiler scans the characters in a program, grouping them into tokens. The 6 basic kinds of tokens are identifiers, keywords, separators, operators, literals (either type int, double, boolean, char, or String), and comments.
A basic, grammatically indivisible unit of a language. The symbol that describes a token in the grammar is a terminal symbol. The input of the Bison parser is a stream of tokens which comes from the lexical analyzer. See Symbols.
In computing, a token is a categorized block of text, usually consisting of indivisible characters known as lexemes. A lexical analyser initially reads in lexemes and categorizes them according to function, giving them meaning. This assignment of meaning is known as tokenization.
An atomic piece of data that the filter will be acting on. If text documents are being filtered a token would probably be a sequence of characters from the alphabet (in other words a word). If an image is being procesed a token may be a sequence of bytes describing a pixel or group of pixels. I call it atomic in that the filter will never need to dissect the token in any way, however the filter will require a Hash function and comparison operators. In addition the buckets will require a way to read and write tokens to a std::stream.
a bless'd reference to an array whose first element is an event-type string and whose last element is the literal text of the XML input that generated the event, with intermediate elements varying according to the event type
The values of this type represent tokenized strings. They may not contain newline (LF) or tab (HT) characters. They may not start or end with whitespace. The only occurrences of whitespace allowed inside the string are single spaces, never multiple spaces together. Derived from normalizedString.
n. 1. The smallest syntactic unit generally seen by a compiler or other translator: a keyword, identifier, binary operator (including multicharacter operators such as += and &&), etc. 2. A whitespace-separated word within a string (see question 13.6).
In code, everything that is not whitespace is a token. Each section of text between sections of whitespace is a seperate token. This is a more general term than 'word', because an equal sign is also a token, but might not be counted as a word by some.
Part of a two-factor authentication system to prove a user is who he us supposed to be. A token is a hardware or software device that is used in conjunction with a password login. For example, a key device that must be physically attached to a USB port before an individual is allowed to type in his password to access the network system.
A device that is used to authenticate a user, typically in addition to a username and password. It is usually a credit card-sized device that displays a pseudo random number that changes every few minutes.
A security device about the size of a credit card, a token is used to generate a network ID code. Typically, a user enters a password into the device and then is granted a randomly generated access code that can be used to log onto a network.
In the Sun Ray system, a token must be presented by the user. It is required by the Authentication Manager to consider allowing a user to access the system. It consists of a type and an ID. If the user inserted a smart card, the smart card's type and ID are used as the token. If the user is not using a smart card, the enterprise appliance's built-in type (pseudo) and ID (the unit's Ethernet address) are supplied as the token.
Whenever you log in to UNIX via an AFS account, AFS checks the password you supply to make sure that you are who you claim. If you are, AFS grants you a token and thereby authenticates you as a valid AFS user. Reference Link (http://www.slac.stanford.edu/BFROOT/www/doc/workbook/unix/unix.html#afs_and_nfs)
A physical token some gadget you must own to gain access to for example data. Typical physical tokens today are for example credit cards and smart cards. A smart card is small computer in tamper resistant packaging that may be used to enter really long keys into cryptographic algorithms if you have the equipment.
A credit card size or key FAB sized authentication device that a user carries. It usually displays numbers that change over time and synchronizes with an authentication server on the network, and it may also use a challenge/response scheme with the server. Tokens are based on something you know (a password or PIN) and something you have (an authenticator - the token).
a hardware or software device that performs cryptographic functions and optionally stores public-key certificates, cryptographic keys, and data defined by the application using the cryptographic services
A set of data that is granted after a user authenticates to AFS. A token is used by the Cache Manager when requesting services from AFS servers. A token has an associated lifetime and expires after a set period of time. If your token expires, you no longer have authenticated access to AFS. The standard token lifetime is 25 hours.
a set of data that indicates that a user has been authenticated and is authorized to request files and services on the system. Tokens are granted after a user authenticates to AFS. A token is used by the Cache Manager when requesting services from AFS servers. A token has an associated lifetime and expires after a set period of time.
In authentication, a device used to send and receive challenges and responses during the user authentication process. Tokens may be small, hand-held devices similar to pocket calculators or credit cards.
(1) (n.) A piece of data that is passed around within the software.(2) (n.) A data packet that is in the form of a GSS-API gss_buffer_t structure. Tokens are produced by GSS-API functions for transfer to peer application Tokens are of two types. Context-level tokens contain information that is used to establish or manage a security context. For example, gss_init_sec_context() bundles a context initiator's credential handle, the target machine's name, and flags for various requested services into a token to be sent to the context acceptor. Message tokens (also called per-message tokens or message-level tokens) contain information that is generated by a GSS-API function from message s to be sent to a peer application. For example, gss_get_mic() produces an identifying cryptographic tag for a particular message and stores the tag in a token to be sent to a peer with the message. Technically, a token is considered separate from a message, which is why gss_wrap() is said to produce an output_message and not an output_token.
A collection of data that the AFS server processes accept as evidence that the possessor has successfully proved his or her identity to the cell's AFS authentication service. AFS assigns the identity anonymous to users who do not have a token.
When you login to a machine in AFS you must be issued a "token" in order to become an authenticated AFS user. This token is issued to you automatically at login when you enter your password. Every token has an expiration date associated with it; on CTC machines, tokens are set to expire after 100 hours. To see what tokens you have, enter the command "tokens"
A password that can be used only once, typically generated as needed by a hardware device. Tokens are considered secure because even if one is revealed, it cannot be misused because it is no longer valid after its first use.
Also called a security token or an authentication token. Something a person has that evidences validity, or identity. It is usually a hardware device that resembles a hand-held calculator, since it often has some sort of display and perhaps a keypad for entering numbers. Tokens achieve the goal of "two-factor authentication," considered a strong standard of security when validating who a user is, because accessing a network that uses tokens requires two factors: something the person knows (a password) and something the person has (the token).
In the Windows NT architecture, a token is a system object (type name "Token") representing the subject in access control operations, i.e. the active part (the passive part being the object being accessed). Token objects are usually built by the logon service to represent the security information known about an authenticated user, but they are essentially free-form and can include any combination and number of the possible elements.
A networking format that uses a combination of bits to grant transmission privileges for a work station on a LAN. This series of bit also carries other important information like routing information, access control information, source and destination addresses. When a computer on a LAN has been given the token, it has been given permission to transmit. Think of a token like a baton in a relay race; you have to wait until you have it in your hand before you run.
A bit pattern that travels continuously in a predetermined direction along the transmission line of a ring or bus network. It can indicate that the line is currently transmitting information or that it is clear for transmission for the next station that wants to transmit on the network.
A unique packet that is passed around a token ring or FDDI LAN continuously. When a device wishes to transmit, it waits until it receives the token, attaches its message to the token, and transmits it. The device then removes its message from the ring when the token and message return to it.
A special packet that contains data and acts as a messenger or carrier between each computer and device on a ring topology. Each computer must wait for the messenger to stop at its node before it can send data over the network.
A fancy way TI-OS keeps its head straight when with working with text. When working with text input on TI-OS, all letters, numbers, commands, symbols, and any other form of text you can think of, are represented, not with ASCII or Unicode byte-codes, but tokens. (One the data is parsed, it is often converted into another format.) Tokens are one or two bytes in size, but may, on screen, show up as many letters; they, hence, keep size down (or up in some cases). Becuase they have special byte-codes, tokens make parsing expressions easier for TI-OS; instead of having to search through bytes and deciding weather this letter is a reference to a variable or part of a command, it knows, because the letter and the command each have their own byte-codes.
(1) The lowest level single unit of text. Often a word but it may, for example, be a hyphenated word or a date. (2) A unique combination of bits. When a LAN workstation receives a token, permission has been given to transmit.
In networking, a unique combination of bits used to confer transmit privileges to a computer on a local area network. It also carries important information for routing messages over the network, such as source and destination addresses, access control information, route control information, and date checking information. On a token ring network, the token is 24 bits long.
Any nonreducible textual element in data that is being parsed. For example, the use in a program of a variable name, a reserved word, or an operator. Storing tokens as short codes shortens program files and speeds execution. For networking, a unique structured data object or message that circulates continuously among the nodes of a token ring and describes the current state of the network. Before any node can send a message on the network, it must first wait to control the token. See also token ring.
n. 1. A unique structured data object or message that circulates continuously among the nodes of a token ring and describes the current state of the network. Before any node can send a message, it must first wait to control the token. See also token bus network, token passing, token ring network. 2. Any nonreducible textual element in data that is being parsed--for example, the use in a program of a variable name, a reserved word, or an operator. Storing tokens as short codes shortens program files and speeds execution. See also Basic, parse.
A piece of metal intended for currency, and issued by a private party, usually bearing the name of the issuer, and redeemable in lawful money. Also, a coin issued by government, esp. when its use as lawful money is limited and its intrinsic value is much below its nominal value.
Technically, a token is any numismatic issue which has an intrinsic value which is significantly less than its face value or denomination. As this is now the case with most legal coin issues, the term token, in numismatic circles, has come to mean a non-legal numismatic piece which at some point in time, became widely accepted as a medium of exchange with a generally accepted face value.
coin used for a special purpose in place of real money or anything that is a small or insufficient example of something else She said she could see that she was just the token woman on the committee. betoken
Any item, but often resembling a coin, with an exchange value, usually privately issued as opposed to an official government issue. At times issued by businesses to relieve the shortage of official coinage for small change.
A coin-like object redeemable for a particular product or service, such as transportation on a bus or subway - An unofficial coin issued by a business or local government to be used as small change, e.g., in 17th-19th century Britain, and in France during the 20th century
A substitute for a coin.Older ones generally were issued by stores and may not have been accepted at other establishments. oning The term for the color seen on many coins. There are many shades, hues, and pattern variations seen, the result of how, where, and how long a coin is stored.
1. adj. describing a single item, individual or deed, often used for show, such as a token individual of color in an otherwise homogeneously white organization. 2. a small gift or act to indicate acknowledgement, as in a "token gesture". 3. an ersatz coin used to pay for a subway or other toll. 4. an "entity" in programming, such as the next word being read from a file. 5. a programming "marker" used to indicate ownership or some sort of state. See cookie.
A device that involves the reader in some way, often consisting of a perforated label that the reader removes from a sheet and sticks to a designated place on the order card, signifying a desire to buy.
Involvement device, often consisting of a perforated portion of an order card designed to be removed from its original position and placed in another designated area (usually 'yes' or 'no'.) on the order card, to signify a desire to purchase the product or service offered. It is a means to get involvement on the part of the prospect.
An involvement device, usually consisting of an order card designed to be removed from its original position and placed in a designated area on another card, which will signify a desire to subscribe or purchase.
A marker with the railway logo on it that represents a railroad station of that company. On the stock market, it represents the share price of that railway. Square tokens are used to represent the par value of a company.
a little piece of information, hidden in the e-mail header, that can have attributes, such as monetary value (making it a stamp), identity, and representations about message content, among other things
A label or identifier in application source code that is used to determine migration issues. Tokens fall into one of three broad categories: function name, parameter name, or shell command name. For more information, see Migration.
tracer or tag which is attached by the receiving server to the address (URL) of a page requested by a user. A token lasts only through a continuous series of requests by a user, regardless of the length of the interval between requests. Tokens can be used to count unique users.
A data item in the header of an encrypted e-mail message that holds an encrypted copy of the secret key used to encrypt the message; usually encrypted with the recipient’s public key so that only the recipient can decrypt it.
On railways, a token is a physical object which a locomotive driver is required to have or see before entering onto a particular section of single track. The token is clearly endorsed with the name of the section it belongs to.
