While typewriters are the absolute antecedent of all key-based argument access devices, the computer keyboard as a accessory for electromechanical abstracts access and advice derives abundantly from the account of two devices: teleprinters (or teletypes) and keypunches. It was through such accessories that avant-garde computer keyboards affiliated their layouts.
As aboriginal as the 1870s, teleprinter-like accessories were acclimated to accompanying blazon and address banal bazaar argument abstracts from the keyboard beyond telegraph curve to banal ticker machines to be anon afflicted and displayed assimilate ticker tape. The teleprinter, in its added abreast form, was developed from 1903 to 1910 by American automated architect Charles Krum and his son Howard, with aboriginal contributions by electrical architect Frank Pearne. Earlier models were developed alone by individuals such as Royal Earl House and Frederick G. Creed.
Earlier, Herman Hollerith developed the aboriginal keypunch devices, which anon acquired to cover keys for argument and amount access affiliated to accustomed typewriters by the 1930s.
The keyboard on the teleprinter played a able role in point-to-point and point-to-multipoint advice for a lot of of the 20th century, while the keyboard on the keypunch accessory played a able role in abstracts access and accumulator for just as long. The development of the ancient computers congenital electric typewriter keyboards: the development of the ENIAC computer congenital a keypunch accessory as both the ascribe and paper-based achievement device, while the BINAC computer aswell fabricated use of an electromechanically controlled typewriter for both abstracts access assimilate alluring band (instead of paper) and abstracts output.
From the 1940s until the backward 1960s, typewriters were the capital agency of abstracts access and achievement for computing, acceptable chip into what were accepted as computer terminals. Because of the limitations of terminals based aloft printed argument in allegory to the advance in abstracts storage, processing and transmission, a accepted move against video-based computer terminals was afflicted by the 1970s, starting with the Datapoint 3300 in 1967.
The keyboard remained the primary, a lot of chip computer borderline able-bodied into the era of claimed accretion until the addition of the abrasion as a customer accessory in 1984. By this time, text-only user interfaces with dispersed cartoon gave way to analogously graphics-rich icons on screen. However, keyboards abide axial to human-computer alternation to the present, even as adaptable claimed accretion accessories such as smartphones and tablets acclimate the keyboard as an alternative virtual, touchscreen-based agency of abstracts entry.
