Super Key (keyboard Button)
The Super key () is an alternative name for what is commonly labelled as the Windows key or Command key on modern computer keyboards, typically bound and handled as such by Linux and BSD operating systems and software today. The Super key was originally a modifier key on a keyboard designed for Lisp machines at MIT. History The " space-cadet" keyboard, designed in 1978 at MIT for the Lisp machine, introduced two new modifier keys, "Super" and "Hyper", compared to the earlier Knight keyboard also used with Lisp machines. Both keys became supported in the powerful Emacs text editor, which had, or would receive, influential ports on Multics, Unix, and many other operating systems, and saw wide adoption at institutions beyond MIT. Beginning in 1984, the X Window System (a graphical user interface standard for Unix-like operating systems) supported the , , and modifiers, as well as the common Shift, Control, and Alt keys. Unix workstations of that era sometimes featur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Unix-like
A Unix-like (sometimes referred to as UN*X, *nix or *NIX) operating system is one that behaves in a manner similar to a Unix system, although not necessarily conforming to or being certified to any version of the Single UNIX Specification. A Unix-like Application software, application is one that behaves like the corresponding List of POSIX commands, Unix command or Unix shell, shell. Although there are general Unix philosophy, philosophies for Unix design, there is no technical standard defining the term, and opinions can differ about the degree to which a particular operating system or application is Unix-like. Some well-known examples of Unix-like operating systems include Linux, FreeBSD and OpenBSD. These systems are often used on servers as well as on personal computers and other devices. Many popular applications, such as the Apache HTTP Server, Apache web server and the Bash (Unix shell), Bash shell, are also designed to be used on Unix-like systems. Definition The Open ...

Virtual Machine
In computing, a virtual machine (VM) is the virtualization or emulator, emulation of a computer system. Virtual machines are based on computer architectures and provide the functionality of a physical computer. Their implementations may involve specialized hardware, software, or a combination of the two. Virtual machines differ and are organized by their function, shown here: * ''System virtual machines'' (also called full virtualization VMs, or SysVMs) provide a substitute for a real machine. They provide the functionality needed to execute entire operating systems. A hypervisor uses native code, native execution to share and manage hardware, allowing for multiple environments that are isolated from one another yet exist on the same physical machine. Modern hypervisors use hardware-assisted virtualization, with virtualization-specific hardware features on the host CPUs providing assistance to hypervisors. * ''Process virtual machines'' are designed to execute computer programs ...

Desktop Environment
In computing, a desktop environment (DE) is an implementation of the desktop metaphor made of a bundle of programs running on top of a computer operating system that share a common graphical user interface (GUI), sometimes described as a graphical shell. The desktop environment was seen mostly on personal computers until the rise of mobile computing. Desktop GUIs help the user to easily access and edit files, while they usually do not provide access to all of the features found in the underlying operating system. Instead, the traditional command-line interface (CLI) is still used when full control over the operating system is required. A desktop environment typically consists of icons, windows, toolbars, directory (file systems), folders, computer wallpaper, wallpapers and Widget engine, desktop widgets (see Elements of graphical user interfaces and WIMP_(computing), WIMP). A GUI might also provide drag and drop functionality and other features that make the desktop metaphor mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

ISO/IEC 9995
ISO/IEC 9995 ''Information technology — Keyboard layouts for text and office systems'' is an International Organization for Standardization, ISO/International Electrotechnical Commission, IEC standard series defining keyboard layout, layout principles for computer keyboards. It does not define specific layouts but provides the base for national and industry standards which define such layouts. The project of this standard was adopted at ISO in Berlin in 1985 under the proposition of Dr Yves Neuville. The ISO/IEC 9995 standard series dates to 1994 and has undergone several updates over the years. Parts The ISO/IEC 9995 standard series currently (as of December 2023) consists of the following parts: * ISO/IEC 9995-1:2009 ''General principles governing keyboard layouts'' * ISO/IEC 9995-2:2009 ''Alphanumeric section'' ** ISO/IEC 9995-2:2009/Amd 1:2012 * ISO/IEC 9995-3:2010 ''Complementary layouts of the alphanumeric zone of the alphanumeric section'' * ISO/IEC 9995-4:2009 ''Numer ...

Computer Mouse
A computer mouse (plural mice; also mouses) is a hand-held pointing device that detects Plane (mathematics), two-dimensional motion relative to a surface. This motion is typically translated into the motion of the Cursor (user interface)#Pointer, pointer (called a cursor) on a computer monitor, display, which allows a smooth control of the graphical user interface of a computer. The first public demonstration of a mouse controlling a computer system was done by Doug Engelbart in 1968 as part of the Mother of All Demos. Mice originally used two separate wheels to directly track movement across a surface: one in the x-dimension and one in the Y. Later, the standard design shifted to use a ball rolling on a surface to detect motion, in turn connected to internal rollers. Most modern mice use optical mouse, optical movement detection with no moving parts. Though originally all mice were connected to a computer by a cable, many modern mice are cordless, relying on short-range rad ...

Windows 95
Windows 95 is a consumer-oriented operating system developed by Microsoft and the first of its Windows 9x family of operating systems, released to manufacturing on July 14, 1995, and generally to retail on August 24, 1995. Windows 95 merged Microsoft's formerly separate MS-DOS and Microsoft Windows products into a single product and featured significant improvements over its predecessor, most notably in the graphical user interface (GUI) and in its simplified " plug-and-play" features. There were also major changes made to the core components of the operating system, such as moving from a mainly cooperatively multitasked 16-bit architecture of its predecessor Windows 3.1 to a 32-bit preemptive multitasking architecture. Windows 95 introduced numerous functions and features that were featured in later Windows versions, and continue in modern variations to this day, such as the taskbar, the notification area, file shortcuts on the desktop, plug and play driver integration, ...

Microsoft Ergonomic Keyboards
Microsoft has designed and sold a variety of ergonomic keyboards for computers. The oldest is the Microsoft Natural Keyboard, released in 1994, the company's first computer keyboard. The newest models are the Sculpt Ergonomic Keyboard (2013), the Surface Ergonomic Keyboard (2016), and the Microsoft Ergonomic Keyboard (2019). In January 2024, Microsoft announced that it would license the design and manufacturing of the Microsoft Ergonomic Keyboard and Sculpt Ergonomic Keyboard to Incase, as part of an effort to focus more on its Surface-branded accessories. These products will be branded under the Incase name, but as designed by Microsoft. Models In general, ergonomic keyboards are designed to keep the user's arms and wrists in a near-neutral position, which means the slant angle (the lateral rotation angle for the keys in each half relative to the axis of the home row in a conventional keyboard) is approximately 10 to 12.5°, the slope (the angle of the keytop surfaces starting f ...

User Interface
In the industrial design field of human–computer interaction, a user interface (UI) is the space where interactions between humans and machines occur. The goal of this interaction is to allow effective operation and control of the machine from the human end, while the machine simultaneously feeds back information that aids the operators' decision-making process. Examples of this broad concept of user interfaces include the interactive aspects of computer operating systems, hand tools, heavy machinery operator controls and Unit operation, process controls. The design considerations applicable when creating user interfaces are related to, or involve such disciplines as, ergonomics and psychology. Generally, the goal of user interface design is to produce a user interface that makes it easy, efficient, and enjoyable (user-friendly) to operate a machine in the way which produces the desired result (i.e. maximum usability). This generally means that the operator needs to provide mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IBM Model M
Model M keyboards are a group of computer keyboards designed and manufactured by IBM starting in 1985, and later by Lexmark, Lexmark International, Maxi Switch, and Unicomp. The keyboard's different variations have their own distinct characteristics, with the vast majority having a buckling-spring key design and uniform profile, swappable keycaps. Model M keyboards are notable among computer enthusiasts and frequent typists due to their durability, typing-feel consistency, and their tactile and auditory feedback. The popularity of the IBM Personal Computer, IBM PC and its successors made the Model M's design influential: Almost all later general-purpose computer keyboards mimicked its key layout and other aspects of its ergonomics. The layout was standardized by ISO in 1994 and ANSI in 1998, with minor additions—most notably the Windows key and Menu key. The Model M is regarded as a classic and durable piece of hardware.
