Virtuality (software Design)
Virtuality is a term used by Ted Nelson for what he considers one of the central issues of software design. "Virtuality" refers to the seeming of anything, as opposed to its reality. (This has been the dictionary meaning of "virtuality" since at least the 18th century). Everything has a reality and a virtuality. Nelson divides virtuality into two parts: conceptual structure and feel so in every field these have different roles. The conceptual structure of all cars are the same, but the conceptual structure of every movie is different. The reality of a car is important, but the reality of a movie is unimportant—how a shot was made is of interest only to movie buffs. The feel of software Software is a set of computer programs and associated documentation and data. This is in contrast to hardware, from which the system is built and which actually performs the work. At the lowest programming level, executable code consists ..., like the feel of a car, is a matter of lat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ted Nelson
Theodor Holm Nelson (born June 17, 1937) is an American pioneer of information technology, philosopher, and sociologist. He coined the terms ''hypertext'' and ''hypermedia'' in 1963 and published them in 1965. Nelson coined the terms ''transclusion'', ''virtuality'', and ''intertwingularity'' (in ''Literary Machines''). According to a 1997 ''Forbes'' profile, Nelson "sees himself as a literary romantic, like a Cyrano de Bergerac, or 'the Orson Welles of software'." Early life and education Nelson is the son of Emmy Award-winning director Ralph Nelson and Academy Award-winning actress Celeste Holm. His parents' marriage was brief and he was mostly raised by his grandparents, first in Chicago and later in Greenwich Village. Nelson earned a B.A. in philosophy from Swarthmore College in 1959. While there, he made an experimental humorous student film, ''The Epiphany of Slocum Furlow'', in which the titular hero discovers the meaning of life. His contemporary at the college, music ...

Software Design
Software design is the process by which an agent creates a specification of a software artifact intended to accomplish goals, using a set of primitive components and subject to constraints. Software design may refer to either "all the activity involved in conceptualizing, framing, implementing, commissioning, and ultimately modifying complex systems" or "the activity following requirements specification and before programming, as ... na stylized software engineering process." Software design usually involves problem-solving and planning a software solution. This includes both a low-level component and algorithm design and a high-level, architecture design. Overview Software design is the process of envisioning and defining software solutions to one or more sets of problems. One of the main components of software design is the software requirements analysis (SRA). SRA is a part of the software development process that lists specifications used in software engineering.

Software
Software is a set of computer programs and associated documentation and data. This is in contrast to hardware, from which the system is built and which actually performs the work. At the lowest programming level, executable code consists of machine language instructions supported by an individual processor—typically a central processing unit (CPU) or a graphics processing unit (GPU). Machine language consists of groups of binary values signifying processor instructions that change the state of the computer from its preceding state. For example, an instruction may change the value stored in a particular storage location in the computer—an effect that is not directly observable to the user. An instruction may also invoke one of many input or output operations, for example displaying some text on a computer screen; causing state changes which should be visible to the user. The processor executes the instructions in the order they are provided, unless it is instructed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graphical User Interface
The GUI ( "UI" by itself is still usually pronounced . or ), graphical user interface, is a form of user interface that allows users to interact with electronic devices through graphical icons and audio indicator such as primary notation, instead of text-based UIs, typed command labels or text navigation. GUIs were introduced in reaction to the perceived steep learning curve of CLIs ( command-line interfaces), which require commands to be typed on a computer keyboard. The actions in a GUI are usually performed through direct manipulation of the graphical elements. Beyond computers, GUIs are used in many handheld mobile devices such as MP3 players, portable media players, gaming devices, smartphones and smaller household, office and industrial controls. The term ''GUI'' tends not to be applied to other lower-display resolution types of interfaces, such as video games (where HUD (''head-up display'') is preferred), or not including flat screens like volumetric displays because ...
