Keyboard - Keyboard A keyboard is a data entry or control device using a number of keys which are to be pressed by the fingers. There are two main types of keyboard: Alphanumeric keyboards (including the typewriter keyboard, the generic computer keyboard and its descendant the IBM PC keyboard) Musical keyboards Other types of keyboards, known as "numeric keypads", are the Calculator keypad (with the 123 keys near the bottom) the CCITT telephone keypad (with the 123 keys at the top), arguably the most common keyboard layout in the world, with roughly 700,000,000 telephones in the world (estimated, as of 1994).

Keyboard technology - Keyboard technology There are several types of keyboard, usually differentiated by the switch technology employed in their operation. Since there are so many switches needed (usually about 80-110) and because they have to be highly reliable, this usually defines the keyboard. The choice of switch technology affects key response (the positive feedback that a key has been pressed) and travel (the distance needed to push the key to reliably enter a character). Newer models use hybrids of various technologies to achieve greater cost savings. Dome switch keyboard Dome switch keyboards are kind of a hybrid of membrane and mechanical keyboards. They bring two circuit board traces together under a plastic "dome" or bubble. The top of the bubble is coated in some conductive substance. When a.

Keyboard layout - Keyboard layout There are many keyboard layouts, for people to be able to type in different languages. The standard English keyboard layout is known as QWERTY. Various alternatives to the QWERTY layout have been suggested, many claiming advantages such as higher typing speeds. The most famous alternative is the Dvorak Simplified Keyboard.

Keyboard buffer - Keyboard buffer A keyboard buffer is a section of computer memory used to hold keystrokes before they are processed. Keyboard buffers have long been used in command-line processing. As a user enters a command, he sees it echoed on his terminal and can edit it before it is processed by the computer. In time-sharing systems, the location of the buffer depends on whether communications is full duplex or half duplex. In full-duplex systems, keystrokes are transmitted one by one. As the main computer receives each keystroke, it ordinarily appends the character which it represents to the end of the keyboard buffer. The exception is control characters, such as "rub out" or "backspace" which correct typing mistakes by deleting the character at the end of the buffer..
Keyboard shortcut - Keyboard shortcut A keyboard shortcut is a set of keyboard keys that when pressed simultaniously, perform a predefined task. Such a task could be done with the mouse (or other analog input such as a trackball), but would require much longer. Hence, they are a shortcut in that they save the user time. Useful Microsoft Windows keyboard shortcuts: Control+C: Copy currently selected text or object to clipboard Control+V: Paste current contents of clipboard at current location in document Shift+Insert: Paste current contents of clipboard at current location in document Control+X: Cut (remove) currently selected text or object from document and copy it to the clipboard Alt+Tab: Shift focus to next window Windows button+D: Minimize all open windows Windows button+F: Open a search window Alt+F4: Close current.

IBM PC keyboard - IBM PC keyboard Keyboards for the IBM PC are standardized. However during the 20 years of the PC architecture being constantly updated as well several types of keyboards have been developed. They all utilise the QWERTY layout. 83-Key PC/XT Keyboard Layout 84-Key AT Keyboard Layout 101-Key "Enhanced" Keyboard Layout - additional navigation and control keys 102-Key "Enhanced" Keyboard Layouts - additional key to the left to the key) 104-Key "Windows" Keyboard Layout - Windows and menu key added 107-Key "Enhanced" Keyboard Layout - Wake, Sleep, and Power keys added (for power management) There are three types of connectors used to connect the keyboards the main unit The first two are: 5-pin DIN (DIN 41524, "AT") connector 6-pin "mini-DIN" (DIN 45322, "PS/2") connector. They are physically different but electrically.
GKOS keyboard - GKOS keyboard One implementation of the GKOS keyboard The GKOS keyboard standard for small portable terminals is intended for replacing the QWERTY where there is not enough room for a large number of keys but still all QWERTY functions are required. Typical applications are cellular terminals/browsers and tablet PCs. The GKOS keyboard has 6 keys and they are located on the back of the terminal, 3 keys for each hand. The keypad is split between two hands so that the combination of keys to press would not be too difficult physically, and in order to have the keys where the fingers are when you hold a calendar shaped object vertically in front of you by two hands. For letters, numbers and punctuation, the most difficult combination is.
Electronic keyboard - Electronic keyboard This is a stub. You can help Wikipedia by fixing it. Electronic keyboards include synthesizers notably the Moog synthesizer), samplers and frequency divider organs. With the use of sampled sounds and MIDI, true synthesizers have become rare, and more and more the general term electronic keyboard is being used. Compare to electric instruments such as the Fender Rhodes piano, and true electric pianos such as the Yamaha electric grand. On the borderline between the two categories are the Mellotron and the traditional Hammond organ..
Enhanced keyboard - Enhanced keyboard The enhanced keyboard was first made by IBM; it has over 101 keys and is now the standard keyboard for PCss. The major difference between this and previous XT/AT keyboards is the twelve function keys arranged in a line across the top of the keyboard as opposed to ten grouped on the left hand side of the keyboard. See also: keyboard, IBM PC keyboard, Microsoft Natural keyboard.
Dvorak Simplified Keyboard - Dvorak Simplified Keyboard The Dvorak Simplified Keyboard is a keyboard layout which is one of the more common alternatives to the QWERTY layout. It has also been called the Simplified Keyboard or American Simplified Keyboard, but is commonly known as the Dvorak keyboard. It was designed by Drs. August Dvorak and William Dealey in the 1920s and 1930s. The two studied letter frequency and the physiology of the hand and created the layout to adhere to these principles: It is easier to type letters alternating between hands. For maximum speed and efficiency, the most common letters and digraphss should be the easiest to type. This means that they should be on the home row, which is where the fingers rest. Likewise, the least common letters should be on.
Alphanumeric keyboard - Alphanumeric keyboard Alphanumeric keyboards include typewriter and computer keyboards. An alphanumeric keyboard is a device with many keys (usually marked with the letters of the alphabet, the digits, and various extra keys.) After punchcards and paper tape, interaction via teletype-style keyboards became the main input device for computers. During the 1980s and 1990s almost all computers came equipped with them as the main form of interaction, and most users are familiar with using them. There are different types of keyboard technologies. The layout of keys on the modern-day English keyboard is called the QWERTY design, based on the most popular typewriter keyboard layout. This has been further extended to the standard 101-key PC keyboard layout, with the addition of cursor keys, a calculator-style numeric keypad, and two.
Kaypro - or somebody else developing the applications needed in-house. All this software when bought separately would cost more than the whole package including the Kaypro 2, which was a very usable and (at the time) powerful computer for the office and the laboratory. This made the Kaypro very popular, both at work and with well educated professionals also at home – even though the metal casing made it look more of a laboratory instrument than a home/office appliance. The case was constructed of aluminum. The keyboard covered the screen and disk drives, when clipped on. There was no battery, the computer ran off regular AC mains power. There was a legal dispute with regards to the Kaypro 2 main circuit board being an unlicensed copy or clone of the Bigboard design. The.
