System File (Mac OS)
The System suitcase (so-called because its icon depicts a suitcase; officially called the System file) is one of two essential files that make up the classic Mac OS, the other being the Macintosh Finder. If either file is missing or corrupted, a Mac may display a blinking question mark when booting. The suitcase is located in the System Folder, like the Finder file, and contains keyboard layouts, FKEY resources, cursors, icons, sounds, and, in System 6, bitmap fonts, and desk accessories. Mac OS only supports one System file; the presence of more than one System file on a hard disk is likely to cause system instability. History System 1 through 6 In versions released up to and including System 6, the System file could not be opened by the Finder. Files could only be moved into or out of the System file using Apple's built-in Font/DA Mover tool. A large System file could cause system instability and could easily become corrupt, requiring users to wipe and rebuild it. System 7 an ...

Classic Mac OS
Mac OS (originally System Software; retronym: Classic Mac OS) is the series of operating systems developed for the Macintosh family of personal computers by Apple Computer from 1984 to 2001, starting with System 1 and ending with Mac OS 9. The Macintosh operating system is credited with having popularized the graphical user interface concept. It was included with every Macintosh that was sold during the era in which it was developed, and many updates to the system software were done in conjunction with the introduction of new Macintosh systems. Apple released the Macintosh 128K, original Macintosh on January 24, 1984. The System 1, first version of the system software, which had no official name, was partially based on the Lisa OS, which Apple previously released for the Apple Lisa, Lisa computer in 1983. As part of an agreement allowing Xerox to buy Share (finance), shares in Apple at a favorable price, it also used concepts from the Xerox PARC Xerox Alto, Alto computer, which ...

Data Fork
In the pursuit of knowledge, data (; ) is a collection of discrete values that convey information, describing quantity, quality, fact, statistics, other basic units of meaning, or simply sequences of symbols that may be further interpreted. A datum is an individual value in a collection of data. Data is usually organized into structures such as tables that provide additional context and meaning, and which may themselves be used as data in larger structures. Data may be used as variables in a computational process. Data may represent abstract ideas or concrete measurements. Data is commonly used in scientific research, economics, and in virtually every other form of human organizational activity. Examples of data sets include price indices (such as consumer price index), unemployment rates, literacy rates, and census data. In this context, data represents the raw facts and figures which can be used in such a manner in order to capture the useful information out of it. Dat ...

Heinlein and Frank Herbert’s '' Dune'' novels, for example). The company was bought in 1965 by G. P. Putnam's Sons and in years to follow undertook a hardcover line under the Berkley imprint, chiefly but not only for science fiction.

International Thomson Organization
International Thomson Organization (ITO) was a holding company for interests in publishing, travel, and natural resources, that existed from 1978 to 1989. It was formed as a reorganisation of the Thomson Organization, which had been founded by Roy Thomson, 1st Baron Thomson of Fleet (Lord Thomson of Fleet; 1894–1976) in 1959. It merged with Thomson Newspapers to become the Thomson Corporation in 1989.

Dragging And Dropping
In computer graphical user interfaces, drag and drop is a pointing device gesture in which the user selects a virtual object by "grabbing" it and dragging it to a different location or onto another virtual object. In general, it can be used to invoke many kinds of actions, or create various types of associations between two abstract objects. As a feature, drag-and-drop support is not found in all software, though it is sometimes a fast and easy-to-learn technique. However, it is not always clear to users that an item can be dragged and dropped, or what is the command performed by the drag and drop, which can decrease usability. Actions The basic sequence involved in drag and drop is: * Move the pointer to the object * Press, and hold down, the button on the mouse or other pointing device, to "grab" the object * "Drag" the object to the desired location by moving the pointer to this one * "Drop" the object by releasing the button Dragging requires more physical effort th ...

Macintosh Finder
The Finder is the default file manager and graphical user interface shell used on all Macintosh operating systems. Described in its "About" window as "The Macintosh Desktop Experience", it is responsible for the launching of other applications, and for the overall user management of files, disks, and network volumes. It was introduced with the first Macintosh computer, and also exists as part of GS/OS on the Apple IIGS. It was rewritten completely with the release of Mac OS X in 2001. In a tradition dating back to the Classic Mac OS of the 1980s and 1990s, the Finder icon is the smiling screen of a computer, known as the Happy Mac logo. Features The Finder uses a view of the file system that is rendered using a desktop metaphor; that is, the files and folders are represented as appropriate icons. It uses a similar interface to Apple's Safari browser, where the user can click on a folder to move to it and move between locations using "back" and "forward" arrow buttons. Like ...

Font/DA Mover
A desk accessory (DA) in computing is a small transient or auxiliary application that can be run concurrently in a desktop environment with any other application on the system. Early examples, such as Sidekick and Macintosh desk accessories, used special programming models to provide a small degree of multitasking on systems that initially did not have any other multitasking ability. Personal information managers Early personal information managers, such as Norton Desktop and Borland's Sidekick, provided pop-up calculator, alarm, calendar and other functions for single-tasking operating systems like MS-DOS using terminate-and-stay-resident techniques. Apple Macintosh Introduced in 1984 as part of the operating system for the Apple Macintosh computer, a Desk Accessory (DA) was a piece of software written as a device driver, conforming to a particular programming model. The purpose of this model was to permit very small helper-type applications to be run concurrently with a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
System 6
System 6 (or System Software 6) is a graphical user interface-based operating system for Macintosh computers, made by Apple Computer It was released in 1988, and is part of the classic Mac OS series. It is a monolithic operating system, with cooperative multitasking based on an improved MultiFinder. The boxed version cost , and it was included with all new Macintosh computers until 1991, when it was succeeded by System 7. Overview MacroMaker The MacroMaker utility was introduced in System 6. It records mouse and keyboard input as macros, and has a unique user interface intended to look and act like a tape recorder. MacroMaker was criticized for its lack of features when compared to Microsoft's AutoMac III, which was already available commercially. As MacroMaker records only the locations of mouse-clicks inside windows and not what is being clicked on or exactly when, it can not be used to automate actions in more sophisticated programs. The pre-recorded clicks miss buttons if th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
