Overview
A computer keyboard is a peripheral input device modeled after a typewriter keyboard, which uses an arrangement of buttons or switches to act as mechanical levers or electronic switches. Replacing early punched cards and paper tape technology, interaction via teleprinter-style keyboards has been the main input method for computers since the 1970s, supplemented by the mouse since the 1980s. Keyboard keys usually have a set of characters etched or printed on them, usually Each keystroke corresponds to a single written symbol. However, producing some symbols may require pressing and holding several keys simultaneously or in sequence, so 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 keystrokes is generally left to software: the information sent to the computer, the scan code, tells it only which physical key (or keys) was pressed or released. Used as a text input interface for typing text, numbers, and symbols in application software such as a word processor, web browser, or social media application. While typewriters are the eventual ancestor of all key-based text input devices, the computer keyboard is an electromechanical data entry and communication device that is largely derived from the usefulness of two devices: teleprinters (or teleprinters) and keypunches. Through these devices, modern computer keyboards inherited their layouts. As early as the 1870s, teleprinter-like devices were used to type text data for the stock market and simultaneously transmit it from the keyboard over telegraph lines to stock ticker devices to be transcribed. The teleprinter, in its most modern form, was developed from 1907 to 1910 by American mechanical engineer Charles Crum and his son Howard, with early contributions by electrical engineer Frank Byrne. Previous models were developed separately by individuals such as the Royal Earl House and Frederick G. Creed. Earlier, Herman Hollerith developed the first keyhole devices, which soon evolved to include text and number entry keys similar to ordinary typewriters by the 1930s. The teleprinter played a strong role in point-to-point and point-to-multipoint communication for most of the 20th century, while the keyboard on a keyhole device played a strong role in data entry and storage for a long time. Development of the earliest computers included electric typewriter keyboards: the development of the ENIAC computer included a keyhole device as the paper input and output device, while the BINAC computer also used an electromechanically controlled typewriter for both data entry on magnetic tape (instead of paper) and data output. The keyboard remained the primary and most integral computer peripheral in the personal computing era until the introduction of the mouse as a consumer device in 1984. By this time, text-only user interfaces with sparse graphics had given way to graphically rich icons on the screen. However, keyboards remain central to human-computer interaction to the present, even as portable personal computing devices such as smartphones and tablets have adapted the keyboard as an optional touchscreen-based virtual means for data entry.
