Words starting with datare
Maybe these words will be useful:
- datary — the head of the dataria (deɪˈtɛərɪə ), the papal office that assesses candidates for benefices reserved to the Holy See
- dataria — the papal office that assesses candidates for benefices reserved to the Holy See
- dataries — plural of datary.
- data feed — (data, architecture) Some process for transferring data from one system to another in a predetermined form.
- data flow — (architecture) A data flow architecture or language performs a computation when all the operands are available. Data flow is one kind of data driven architecture, the other is demand driven. It is a technique for specifying fine-grain concurrency, usually in the form of two-dimensional graphs in which instructions that are available for concurrent execution are written alongside each other while those that must be executed in sequence are written one under the other. Data dependencies between instructions are indicated by directed arcs. Instructions do not reference memory since the data dependence arcs allow data to be transmitted directly from the producing instruction to the consuming one. Data flow schemes differ chiefly in the way that they handle re-entrant code. Static schemes disallow it, dynamic schemes use either "code copying" or "tagging" at every point of reentry. An example of a data flow architecture is MIT's VAL machine.
- data flow analysis — (programming) A process to discover the dependencies between different data items manipulated by a program. The order of execution in a data driven language is determined solely by the data dependencies. For example, given the equations 1. X = A + B 2. B = 2 + 2 3. A = 3 + 4 a data-flow analysis would find that 2 and 3 must be evaluated before 1. Since there are no data dependencies between 2 and 3, they may be evaluated in any order, including in parallel. This technique is implemented in hardware in some pipelined processors with multiple functional units. It allows instructions to be executed as soon as their inputs are available, independent of the original program order.
- data fork — Macintosh file system
- data frame — activation record
- data glove — (hardware, virtual reality) An input device for virtual reality in the form of a glove which measures the movements of the wearer's fingers and transmits them to the computer. Sophisticated data gloves also measure movement of the wrist and elbow. A data glove may also contain control buttons or act as an output device, e.g. vibrating under control of the computer. The user usually sees a virtual image of the data glove and can point or grip and push objects. Examples are Fifth Dimension Technologies (5DT)'s 5th Glove, and Virtual Technologies' CyberGlove. A cheaper alternative is InWorld VR's CyberWand.
- data hierarchy — The system of data objects which provide the methods for information storage and retrieval. Broadly, a data hierarchy may be considered to be either natural, which arises from the alphabet or syntax of the language in which the information is expressed, or machine, which reflects the facilities of the computer, both hardware and software. A natural data hierarchy might consist of bits, characters, words, phrases, sentences, paragraphs, and chapters. One might use components bound to an application, such as field, record, and file, and these would ordinarily be further specified by having data descriptors such as name field, address field, etc. On the other hand, a machine or software system might use bit, byte, word, block, partition, channel, and port. Programming languages often provide types or objects which can create data hierarchies of arbitrary complexity, thus allowing software system designers to model language structures described by the linguist to greater or lesser degree. The distinction between the natural form of data and the facilities provided by the machine may be obscure, because users force their needs into the molds provided, and programmers change machine designs. As an example, the natural data type "character" and the machine type "byte" are often used interchangeably, because the latter has evolved to meet the need of representing the former.
