Physically, computer keyboards are an arrangement of rectangular buttons, or "keys". Keyboards typically have characters engraved or printed on the keys; in most cases, each press of a key corresponds to a single written symbol. However, to produce some symbols requires pressing and holding several keys simultaneously or in sequence; other keys do not produce any symbol, but instead affect the operation of the computer or the keyboard itself.

A foldable keyboard

There exist a large number of different arrangements of symbols on keys. These different keyboard layouts arise mainly because different people need easy access to different symbols; typically, this is because they are writing in different languages, but specialized keyboard layouts for mathematics, accounting, and computer programming also exist.

Most of the more common keyboard layouts (QWERTY-based and similar) were designed in the era of the mechanical typewriters, so their ergonomics had to be slightly compromised in order to tackle some of the technical limitations of the typewriters. The letters were attached to levers that needed to move freely; jamming would result if commonly-used letters were placed too close to one another. With the advent of modern electronics, this is no longer an issue. QWERTY layouts and their brethren had been a de facto standard for decades prior to the introduction of the very first computer keyboard, and were primarily adopted for electronic keyboards for this reason. Alternative layouts do exist, the best known of which is the Dvorak Simplified Keyboard; however, these layouts are not in widespread use. For the song by Linkin Park, see QWERTY (song). ... The Dvorak Simplified Keyboard layout // The Dvorak Simplified Keyboard (pronounced ) is a keyboard layout patented in 1936 by Dr. August Dvorak, an educational psychologist and professor of education[1] at the University of Washington in Seattle,[2] and William Dealey as an alternative to the more common QWERTY layout. ...


The number of keys on a keyboard varies from the original standard of 1101 keys to the 104-key windows keyboards and all the way up to 130 keys or more, with many of the additional keys being symbol-less programmable keys that can simulate multiple such as starting a web browser or e-mail client. There also were "Internet keyboards," sold in the late 1990s, that replaced the function keys with pre-programmed internet shortcuts. Pressing the shortcut keys would launch a browser to go to that website. An example of a Web browser (Internet Explorer 7) A Web browser is a software application that enables a user to display and interact with text, images, and other information typically located on a Web page at a website on the World Wide Web or a local area network. ...

Connection types

There are several different ways of connecting a keyboard which have evolved over the years. These include the standard AT (DIN-5) connector commonly found on pre-80486 motherboards, which was eventually replaced by the PS/2 and now USB connection. Prior to the iMac line of systems, Apple Computer used ADB, a proprietary system, for its keyboard connector. 5 pin 180° DIN connector 4 pin Mini-DIN S-Video connector Speaker DIN line socket (left) and plug DIN connectors are multi-pin electrical connectors based on a DIN standard. ...

A standard keyboard is physically quite large, as each key must remain large enough to be easily pressed by fingers. Other types of keyboards have been proposed for small portable equipment where a standard keyboard is too large. One way to reduce the size of the keyboard is to reduce the number of keys and use chording keyer, i.e. pressing several keys simultaneously. For example, the GKOS keyboard has been designed for small wireless devices. Other two-handed alternatives more akin to a game controller, such as the AlphaGrip, are also used as a way to input data and text.

Another way to reduce the size of a keyboard is to use smaller buttons and pack them closer together. Such keyboards, often called a "thumbboard" (thumbing) are used in some personal digital assistants such as the Treo and BlackBerry and some Ultra-Mobile PCs such as the OQO.

Historical

While the IBM PC was hardly the first electronic keyboard, it does merit particular mention. The original IBM PC/XT had 83 keys, the AT keyboard had 84 (adding a SysRq key and separating keys into sections), next the "Enhanced" 101 keys (duplicating the cursor movement keys from the numeric pad, adding the function key row along the top, other minor changes, and of course the often maligned control-key/caps-lock switch. The above-mentioned 104 keys were obtained by adding three "windows" keys. [2] The IBM PC keyboard and its derivative computer keyboards are standardized. ...

In modern computers the interpretation of keypresses is generally left to the software. Modern keyboards distinguish each physical key from every other and report all keypresses to the controlling software. This flexibility is not often taken advantage of and it usually does not matter, for example, whether the left or right shift key is held down in conjunction with another character, even though they are coded as completely separate keys.


Commands

A keyboard is also used to type commands in a computer. One famous example on the PC is the Ctrl+Shift+Esc combination. With current versions of Windows, this brings up the Task manager, which allows users to manage currently-running processes, shut down the machine, etc. Under Linux, MS-DOS and some older versions of Windows, Ctrl+Alt+Del performs either a 'cold' or 'warm' reboot. On mac operating systems, pressing cmd+option+esc brings up a force quit dialog. IBM PC (IBM 5150) with keyboard and green screen monochrome monitor (IBM 5151), running MS-DOS 5. ...

Games

A keyboard is one of the primary methods of control in computer games. For instance, the arrow keys or a group of letters resembling the pattern of the arrow keys, like WASD, can be used for movement of a game character. In many games, keys can be configured to the user's preferences. Alphabet keys are also sometimes used to perform actions starting with that letter. (e.g. pressing j to jump). “Computer Games” redirects here. ... Arrow keys Arrow keys are buttons on a computer keyboard that move the cursor in a specified direction. ... WASD positioning Made popular by Quake, WASD (or WSAD) is a set of four keys on the left-hand side of a QWERTY computer keyboard often used to control the players movement in first-person/third-person (FPS/TPS) computer games. ...


Buying considerations

Some low-quality keyboards suffer problems when multiple keys are pressed in quick succession; some types of keyboard circuitry will register a maximum number of keys at one time. This is undesirable for games (designed for multiple keypresses, e.g. casting a spell while holding down keys to run) and undesirable for extremely fast typing (hitting new keys before the fingers can release previous keys). A common side effect of this shortcoming is called "phantom key blocking": on some keyboards, pressing three keys simultaneously sometimes resulted in a 4th keypress being registered. Modern keyboards prevent this from happening by blocking the 3rd key in certain key combinations, but while this prevents phantom input, it also means that when two keys are depressed simultaneously, many of the other keys on the keyboard will not respond until one of the two depressed keys is lifted. Better keyboards are designed so that this happens infrequently in office programs, but it remains a problem in games even on expensive keyboards, due to wildly different and/or configurable key/command layouts in different games. Tug of war is an easily organized, impromptu game that requires little equipment. ...


How it works

The following briefly describes a "dome-switch" keyboard (sometimes incorrectly referred to as a membrane keyboard), the most common type in use today: Keyboard construction, in four layers, of a typical notebook computer keyboard There are many types of keyboard, usually differentiated by the switch technology employed in their operation. ... A membrane keyboard is a computer keyboard whose keys are not separate, moving parts, as with the majority of other keyboards, but rather have only outlines and symbols printed on a flat, flexible surface. ...

  1. When a key is pressed, it pushes down on a rubber dome sitting beneath the key. A conductive contact on the underside of the dome touches (and hence connects) a pair of conductive lines on the circuit below.
  2. This bridges the gap between them and allows current to flow (i.e. the circuit goes from open to closed), changing the signal strength.
  3. A scanning signal is emitted by the chip along the pairs of lines to all the keys. When the signal in one pair becomes different, the chip generates a "make code" corresponding to the key connected to that pair of lines.
  4. The code generated is sent to the computer either via a keyboard cable (using on-off electrical pulses to represent bits) or over a wireless connection. It may be repeated.
  5. A chip inside the computer receives the signal bits and decodes them into the appropriate keypress. The computer then decides what to do on the basis of the key pressed (e.g. display a character on the screen, or perform some action).
  6. When the key is released, a break code (different than the make code) is sent to indicate the key is no longer pressed. If the break code is missed (e.g. due to a keyboard switch) it is possible for the keyboard controller to believe the key is pressed down when it is not, which is why pressing then releasing the key again will release the key. (since another break code is sent.)

Other types of keyboards function in a similar manner, the main differences being how the individual key-switches work. For more on this subject refer to the article on keyboard technology.

Certain key presses are special, namely Ctrl-Alt-Delete and SysRq, but what makes them special is partly the software itself but also partly that the keyboard controller sends the computer a hardware interrupt which is guaranteed to get the right attention. Basically, both take a different, more trusted route much harder to intercept. This article is about Control-Alt-Delete, the keyboard shortcut. ...
