why the alphabets have been shuffled in the keyboard?

Answer 1

because thy wanted to

Answer 2

In 1874 Remington & Sons manufactured the first commercial typewriter, called the Remington Number 1. This typewriter was designed by Christopher Sholes and used the "QWERTY" keyboard we are all familiar with.
This early typewriter used a mechanism with characters on the end of a bar. When a key was struck, a linkage would swing the bar into a tape coated with ink. When the character struck the tape, the impression of the character was transferred onto the paper, which was positioned behind the tape.

Sholes' original prototypes had a problem with the bars colliding with each other and jamming. So the story goes that he arranged the keys with the most common letters in hard to reach spots, to slow typists down and try to avoid this problem.

Whatever the reason for the QWERTY layout, it seems pretty unlikely that one of the first keyboard layouts invented would be perfect. The QWERTY keyboard is very different from the Dvorak keyboard layout. The Dvorak keyboard layout tries to minimize the distance traveled by the fingers. It also tries to make the typist alternate hands on consecutive letters as often as possible.

The Dvorak layout places all of the most commonly used letters in the home row so your fingers don't have to move at all to hit these keys. The left hand has all of the vowels and some consonants and the right hand has only consonants. So there are very few words in the English language that can be typed with only one hand on the Dvorak keyboard (two are "papaya" and "opaque"). Both "pumpkin" and "minimum" can be typed with one hand on a QWERTY keyboard -- give it a try.

This site shows the layout of the Dvorak keyboard. If I had typed this article on a Dvorak keyboard my fingers would have traveled 30 meters vs. the 54 meters they traveled on the QWERTY keyboard I use.

Some argue, however, the Dvorak keyboard is no more efficient than QWERTY. An independent study in 1956 showed that QWERTY typists and Dvorak typists had about the same rate of speed, and continued studies don't show a clear winner between the two [ref]. This may explain why QWERTY is still the standard.

If you want to see for yourself, you can switch your keyboard to a Dvorak configuration just by changing a setting on your computer's operating system. Depending on your keyboard you may even be able to pry off the keys and rearrange them in the Dvorak layout.

Answer 3

So many answers, but nobody got it right...

The QWERTY layout dates from the mechanical typewriter.  The conventional typewriter (not ball-type Selectric) has letters on hammers which strike the ribbon into the paper.  They swing from different pivots, but they all have to strike the platen in the same place.  And when two keys are struck in very close succession....

You see where this is going.

When one hammer hasn't cleared the zone before the next comes up, one hammer strikes the other on the back or gets jammed together on its side.  The further apart the hammer pivots are, the less far the hammer has to be back from the platen to leave a clear path for the next one.  Thus, frequently-used letters were placed apart from each other.  This works okay sometimes and not so well other times; if you type "laugh" the L, A and U are on opposite hands and far apart, but the UGH are close together and have the potential to jam much more easily.

Electronic keyboards don't have hammers to jam, so the only factor is how much motion is wasted.  The Dvorak keyboard is supposed to be better than QWERTY, but in reality the difference isn't all that large.  You can go just about anywhere and find a QWERTY keyboard and just do your thing, and that can save more time and grief than the efficiency gains from Dvorak.

Answer 4

The QWERTY keyboard layout was devised in the 1860s by Christopher Sholes, a newspaper editor who lived in Milwaukee, who was also the creator of the first modern typewriter. Originally, the characters on the typewriters he invented were arranged alphabetically, set on the end of a metal bar which struck the paper when its key was pressed. However, once an operator had learned to type at speed, the bars attached to letters that lay close together on the keyboard became entangled with one another, forcing the typist to manually unstick the typebars, and also frequently blotting the document.[1] Sholes decided that the best way out of the difficulty was to find out which letters were most used in the English language, and then to reposition them on the keyboard as far from each other as possible. This reduced typing speed, and so lessened the occurrence of clashing type bars. In this way the QWERTY keyboard was born, named after the first six letters on the top line.

The home row (ASDFGHJKL) of the QWERTY layout is thought to be a remnant of the old alphabetical layout that QWERTY replaced. QWERTY also attempted to alternate keys between hands, allowing one hand to move into position while the other hand strikes home a key. This sped up both the original double-handed hunt-and-peck technique and the later touch typing technique; however, single-handed words such as stewardesses, lollipop and monopoly show flaws in the alternation.

Answer 5

Keyboards are based on typewriter keyboards, and the letters were arranged so that the most used letters are in positions easily reached by fingers when typists are typing using both hadns and all fingers. The very first typewritghter ahd keys in alphabetical order, but typists found it difficilt to use them so the current layout was chosen. The positions of the letter does vary if you are using a different language, where perhaps the j and x are more used, or other letters are used.

Answer 6

In the 50's (or something) people were typing way too fast on the keyboards and giving themselves RSI, and prevent damaging the typewriters.

The keyboard has now a QWERTY layout in order to slow down typing speeds and reduce injuries.

Answer 7

This was done with the early mechanical typewriters to slow typing down, and reduce the possibility of the keyboard jamming. Since then it has just stayed that way.

Answer 8

The letters that are used the most, like E, D, S and so on, are positioned so that you don't have to extend your fingers. Letters like Q and Z are a bit farther away, since they are not used quite as frequently as others. It makes for a faster typing.

Answer 9

It was designed to slow typists down when using manual keyboards. The were typing so fast that the hammers would get jammed together.

Answer 10

apparently our keyboar was really bad and easily gave us arthiritus or something. They managed to devise a keyboard that mreans the works/letterswe type the most, will be easier and better for our hands with long term use.

Answer 11

To make it easier to touch type. The most commonly keys used are where the most easy to use fingers are. That sounds really convoluted but I hope you understand me!
