The letters are grouped in two ways:
- one to make the keys used most often (in English) close together in two groups
The most used keys are in two clusters at the "home" position for each hand.
- second to make keys used consecutively farther apart
The QWERTY computer keyboard is copied from the typewriter keyboard, which originally used metal arms that traveled up to strike the paper. If the frequently used keys were next to each other, they could cause the arms to jam together (while one was going up and the other was coming back). This can still happen with typewriters using the QWERTY layout, but much less frequently.
The QWERTY keyboard was designed by John Densmore for the first successful typing machines, created by inventor Christopher Latham Sholes in 1867. These were subsequently built and sold by the Remington company in 1873.
because they are...
The letters on an Arabic keyboard are arranged in exactly the same way as any other keyboard including English, and each Arabic letter corresponds to the correct letter in English.
because it is cool that way
because the inventor of the keyboards last name was qwerty
to keep the hammers from hitting each other and jamming.
yes they are
Before keyboards, they used type writers and the letters got jammed so they reorganized the keyboard so the letters wouldn't get jammed when they typed.
Tradition and familiarity.
Modern keyboard keys are arranged according to the QWERTY design by Christopher Sholes.
they arranged it from the top row to the bracket on the keyboard.
The average keyboard is arranged in Qwerty. Look at the upper left hand corner, and you'll see that on the top line, Qwerty is spelled. I think that Qwerty is the company's name, or the inventor's name.
The French type of keyboard is called "azerty" (vs the English "qwerty"). Link goes to image of the layout of the azerty keyboard.
