The piano was revolutionary, because a pianist could vary the volume or dynamics of the sound by varying the vigor with which each key was struck. The pianos full name is gravicmbalo con piano e forte meaning harpsichord with soft and loud but can be shortened to piano forte, which means soft loud in Italian. In its current form, the piano is a product of the late 1. Mozart, Haydn, and Beethoven. In fact, the modern piano is significantly different from even the 1. Liszt, Chopin, and Brahms. See Piano history and musical performance. Keyboard instruments were further developed in the early twentieth century. Early electromechanical instruments, such as the Ondes Martenot, appeared early in the century. This was a very important contribution to the keyboards history. Modern keyboardseditMuch effort has gone into creating an instrument that sounds like the piano but lacks its size and weight. The electric piano and electronic piano were early efforts that, while useful instruments in their own right, did not convincingly reproduce the timbre of the piano. Electric and electronic organs were developed during the same period. More recent electronic keyboard designs strive to emulate the sound of specific make and model pianos using digital samples and computer models.

Typing on a computer keyboard. In computing, a computer keyboard is a typewriter style device which uses an arrangement of buttons or keys to act as a mechanical lever or electronic switch. Following the decline of punch cards and paper tape, interaction via teleprinter style keyboards became the main input device for computers. A keyboard typically has characters engraved or printed on the keys buttons and each press of a key typically corresponds to a single written symbol. However, to produce some symbols requires pressing and holding several keys simultaneously or in sequence. While most keyboard keys produce letters, numbers or signs characters, other keys or simultaneous key presses can produce actions or execute computer commands. Despite the development of alternative input devices, such as the mouse, touchscreen, pen devices, character recognition and voice recognition, the keyboard remains the most commonly used device for direct human input of alphanumeric data into computers. In normal usage, the keyboard is used as a text entry interface to type text and numbers into a word processor, text editor or other programs. In a modern computer, the interpretation of key presses is generally left to the software. A computer keyboard distinguishes each physical key from every other and reports all key presses to the controlling software. Keyboards are also used for computer gaming, either with regular keyboards or by using keyboards with special gaming features, which can expedite frequently used keystroke combinations. A keyboard is also used to give commands to the operating system of a computer, such as Windows Control Alt Delete combination, which brings up the system security options screen. A command line interface is a type of user interface operated entirely through a keyboard, or another device doing the job of one. HistoryeditWhile typewriters are the definitive ancestor of all key based text entry devices, the computer keyboard as a device for electromechanical data entry and communication derives largely from the utility of two devices teleprinters or teletypes and keypunches. It was through such devices that modern computer keyboards inherited their layouts. As early as the 1. The teleprinter, in its more contemporary form, was developed from 1. American mechanical engineer Charles Krum and his son Howard, with early contributions by electrical engineer Frank Pearne. Earlier models were developed separately by individuals such as Royal Earl House and Frederick G. Creed. Earlier, Herman Hollerith developed the first keypunch devices, which soon evolved to include keys for text and number entry akin to normal typewriters by the 1. The keyboard on the teleprinter played a strong role in point to point and point to multipoint communication for most of the 2. The development of the earliest computers incorporated electric typewriter keyboards the development of the ENIAC computer incorporated a keypunch device as both the input and paper based output device, while the BINAC computer also made use of an electromechanically controlled typewriter for both data entry onto magnetic tape instead of paper and data output. From the 1. 94. 0s until the late 1. Because of the limitations of terminals based upon printed text in comparison to the growth in data storage, processing and transmission, a general move toward video based computer terminals was effected by the 1. Datapoint 3. 30. 0 in 1. The keyboard remained the primary, most integrated computer peripheral well into the era of personal computing until the introduction of the mouse as a consumer device in 1. Phast Crack. By this time, text only user interfaces with sparse graphics gave way to comparatively graphics rich icons on screen. However, keyboards remain central to human computer interaction to the present, even as mobile personal computing devices such as smartphones and tablets adapt the keyboard as an optional virtual, touchscreen based means of data entry. Keyboard typeseditOne factor determining the size of a keyboard is the presence of duplicate keys, such as a separate numeric keyboard, for convenience. Further the keyboard size depends on the extent to which a system is used where a single action is produced by a combination of subsequent or simultaneous keystrokes with modifier keys, see below, or multiple pressing of a single key. A keyboard with few keys is called a keypad. See also text entry interface. Another factor determining the size of a keyboard is the size and spacing of the keys.

The switch mechanism for a laptop keyboard is more likely to be a scissor switch than a rubber dome this is opposite the trend for full size keyboards. Flexible keyboardseditFlexible keyboards are a junction between normal type and laptop type keyboards normal from the full arrangement of keys, and laptop from the short key distance. Additionally, the flexibility allows the user to foldroll the keyboard for better storage and transfer. However, for typing the keyboard must be resting on a hard surface.
