Cursor (user Interface)
In human–computer interaction, a cursor is an indicator used to show the current position on a computer monitor or other display device that will respond to input from a text input or pointing device. The mouse cursor is also called a pointer, owing to its resemblance in usage to a pointing stick. Etymology ''Cursor'' is Latin for 'runner'. A cursor is a name given to the transparent slide engraved with a hairline used to mark a point on a slide rule. The term was then transferred to computers through analogy. On 14 November 1963, while attending a conference on computer graphics in Reno, Nevada, Douglas Engelbart of Augmentation Research Center (ARC) first expressed his thoughts to pursue his objective of developing both hardware and software computer technology to "augment" human intelligence by pondering how to adapt the underlying principles of the planimeter to inputting X- and Y-coordinate data, and envisioned something like the cursor of a mouse he initially called ...

Cursor (databases)
In computer science, a database cursor is a mechanism that enables traversal over the records in a database. Cursors facilitate subsequent processing in conjunction with the traversal, such as retrieval, addition and removal of database records. The database cursor characteristic of traversal makes cursors akin to the programming language concept of iterator. Cursors are used by database programmers to process individual rows returned by database system queries. Cursors enable manipulation of whole result sets at once. In this scenario, a cursor enables the sequential processing of rows in a result set. In SQL procedures, a cursor makes it possible to define a result set (a set of data rows) and perform complex logic on a row by row basis. By using the same mechanics, a SQL procedure can also define a result set and return it directly to the caller of the SQL procedure or to a client application. A cursor can be viewed as a pointer to one row in a set of rows. The cursor can only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pointer (computer Programming)
In computer science, a pointer is an object in many programming languages that stores a memory address. This can be that of another value located in computer memory, or in some cases, that of memory-mapped computer hardware. A pointer ''references'' a location in memory, and obtaining the value stored at that location is known as ''dereferencing'' the pointer. As an analogy, a page number in a book's index could be considered a pointer to the corresponding page; dereferencing such a pointer would be done by flipping to the page with the given page number and reading the text found on that page. The actual format and content of a pointer variable is dependent on the underlying computer architecture. Using pointers significantly improves performance for repetitive operations, like traversing iterable data structures (e.g. strings, lookup tables, control tables and tree structures). In particular, it is often much cheaper in time and space to copy and dereference pointers th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cursor (slide Rule)
The slide rule is a mechanical analog computer which is used primarily for multiplication and division, and for functions such as exponents, roots, logarithms, and trigonometry. It is not typically designed for addition or subtraction, which is usually performed using other methods. Maximum accuracy for standard linear slide rules is about three decimal significant digits, while scientific notation is used to keep track of the order of magnitude of results. Slide rules exist in a diverse range of styles and generally appear in a linear, circular or cylindrical form, with slide rule scales inscribed with standardized graduated markings. Slide rules manufactured for specialized fields such as aviation or finance typically feature additional scales that aid in specialized calculations particular to those fields. The slide rule is closely related to nomograms used for application-specific computations. Though similar in name and appearance to a standard ruler, the slide ru ...

Cursor Models
Cursor Modell was a German company making models of antique and modern German vehicles. It is best known for its plastic replicas of vehicles mainly of the era 1880 to about 1920, produced for, and sold in, the Daimler-Benz museum in Stuttgart. Museum models Cursor started making ultra detailed 1:40 scale plastic replicas of 1880–1920 era Mercedes-Benzes and Daimlers about 1969. The first models were produced by model maker Wiking and then immediately taken over by Cursor. Models produced (sometimes marked with the initials C.R.) were mostly of vehicles on exhibit at the Mercedes-Benz museum, like the 1886 "Dreirad" three-wheeler and Daimler's gas powered horse-buggy style "Motorwagen" of the same year. These were the first gas powered vehicles ever produced. Also made were an 1895 Erster Benz omnibus and an 1896 firewagon, and a 1904 MAN Bussing omnibus. David Sinclair, an influential dealer to the diecast collecting hobby, imported some of the first Cursor Models to the Unit ...

Automan
''Automan'' is an American superhero television series produced by Glen A. Larson. It aired for 12 episodes (although 13 were made) on ABC between 1983 and 1984. It consciously emulates the stylistic trappings of the Walt Disney Pictures live-action film ''Tron'', in the context of a superhero TV series. The series was later shown in reruns on the Sci-Fi Channel. Synopsis ''Automan'' (the "Automatic Man") follows the adventures of a police officer and computer programmer named Walter Nebicher ( Desi Arnaz Jr.), who has created an artificially intelligent crime fighting program that generated a hologram (Chuck Wagner) able to leave the computer world at night and fight crime. While in the real world, Automan posed as a government agent by the name of "Otto J. Mann." This was a secret to all except Walter's close associate, Roxanne Caldwell (Heather McNair). Nebicher could merge with Automan to become one being, sharing consciousness and skills, while retaining Automan's invulne ...
