This is related to the history of the typewriter which was found first by Christopher Latham Sholes (1868). When creating a prototype typewriter before, in fact very allows us to type faster. Too fast in typing the possibility, to the extent that is often a problem at that time. Often when the button is pressed, the letter stems (slug) the stamping mechanical tape was wound up, more often caused because rods were mutually relates (jamming). Because of the puzzling over the solution at the time, Christopher Latham Sholes thus ruffled that order so as to find a combination that is considered the most difficult to use in typing.
The objective is clear, to avoid mechanical mistakes that often occur before. Eventually the arrangement on this typewriter-derived on the keyboard as the computer input and in 1973 established a standard keyboard as ISO (International Standards Organization). There are actually several standard keyboard arrangement used today. Call it ASK (the American Simplified Keyboard), commonly called DVORAK found by Dr. August Dvorak circa 1940.
In research at the time, DVORAK layout allows us to type more efficiently. But perhaps because it is too late, finally DVORAK should be subject to due to the dominance of the QWERTY is already happening on the organisations of the world and they don’t want to risk the rush when replacing the DVORAK keyboard arrangement. The only recognition is coming from ANSI (American National Standard Institute) who agreed to the arrangement of Dvorak’s keyboard as a% u201Calternatif% u201D version around 1970.
Another keyboard arrangement of the order of development still is a QWERTY QWERTZ are used in countries such as Hungary, Switzerland, Germany, etc. AZERTY France and Belgium by the States, QZERTY, etc.
