IBM PC Keyboard
The keyboard for IBM PC-compatible computers is standardized. However, during the more than 30 years of PC architecture being frequently updated, many keyboard layout variations have been developed. A well-known class of IBM PC keyboards is the Model M. Introduced in 1984 and manufactured by IBM, Lexmark, Maxi-Switch and Unicomp, the vast majority of Model M keyboards feature a buckling spring key design and many have fully swappable keycaps. Keyboard layouts The PC keyboard changed over the years, often at the launch of new IBM PC versions. Common additions to the standard layouts include additional power management keys, volume controls, media player controls (e.g. "Play/Pause", "Previous track", "Next track) and miscellaneous user-configurable shortcuts for email client, World Wide Web browser, etc. The IBM PC layout, particularly the Model M, has been extremely influential, and today most keyboards use some variant of it. This has caused problems for applications devel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keyboard (computing)
A computer keyboard is a peripheral input device modeled after the typewriter keyboard which uses an arrangement of buttons or keys to act as mechanical levers or electronic switches. Replacing early punched cards and paper tape technology, interaction via teleprinter-style keyboards have been the main input method for computers since the 1970s, supplemented by the computer mouse since the 1980s. Keyboard keys (buttons) typically have a set of characters engraved or printed on them, and each press of a key typically corresponds to a single written symbol. However, producing some symbols may require pressing and holding several keys simultaneously or in sequence. While most keys produce characters (letters, numbers or symbols), other keys (such as the escape key) can prompt the computer to execute system commands. In a modern computer, the interpretation of key presses is generally left to the software: the information sent to the computer, the scan code, tells it only ...

Model M Keyboard
Model M designates a group of computer keyboards designed and manufactured by IBM starting in 1985, and later by Lexmark International, Maxi Switch, and Unicomp. The keyboard's many variations have their own distinct characteristics, with the vast majority having a buckling-spring key design and 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 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. Although the computers and computer peripherals produced concurrently with them are considered obsolete, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Windows 95
Windows 95 is a consumer-oriented operating system developed by Microsoft as part of its Windows 9x family of operating systems. The first operating system in the 9x family, it is the successor to Windows 3.1x, and was released to manufacturing on July 14, 1995, and generally to retail on August 24, 1995, almost three months after the release of Windows NT 3.51. Windows 95 merged Microsoft's formerly separate MS-DOS and Microsoft Windows products, 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 to a 32-bit preemptive multitasking architecture, at least when running only 32-bit protected mode applications. Accompanied by an extensive marketing campaign, Windows 95 introduced numerous functions and features that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microsoft Natural Keyboard
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). 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 from the front edge closer to the user towards the top of the keyboard, relative to a horizontal plane) is -7.5°, and the tent or gable angle of each half (the angle of the keytops from the center of the keyboard towards its left and right edges, relative to the horizontal desk surface) is 20 to 30°. ;Notes Natura ...

Windows Key
The Windows logo key (also known as Windows-, win-, start-, logo-, flag-, or super-key) is a keyboard key which was originally introduced on the Microsoft Natural keyboard in 1994. This key became a standard key on PC keyboards. In Windows tapping the key brings up the start menu. performs the same function, in case the keyboard lacks this key. History and usage Historically, the addition of two Windows keys and a menu key marked the change from the 101/102-key to 104/105-key layout for PC keyboards. Compared to the former layout, a Windows key was placed between the left and the left and another Windows key and the menu key were placed between the right (or ) and the right key. The key is predated by the key on Apple computers in the 1980s, and before that by the (or ) key on Lisp/Unix workstation computers in the 1970s. In laptop and other compact keyboards it is common to have just one Windows key (usually on the left). On Microsoft's Entertainment Desktop set ...
