why computer keyboard is shuffled!?

Answer 1

The idea that it was used to slow down typing speed is not quite true. The name "QWERTY" keyboard was the work of inventor C. L. Sholes, who put together the prototypes of the first commercial typewriter back in the 1860's.

For years, popular writers have accused Sholes of deliberately arranging his keyboard to slow down fast typists who would otherwise jam up his sluggish machine. In fact, his motives were just the opposite.

When Sholes built his first model in 1868, the keys were arranged alphabetically in two rows. At the time, Milwaukee was a backwoods town. The crude machine shop tools available there could hardly produce a finely-honed instrument that worked with precision. Yes, the first typewriter was sluggish. Yes, it did clash and jam when someone tried to type with it. But Sholes was able to figure out a way around the problem simply by rearranging the letters. Looking inside his early machine, we can see how he did it.

The first typewriter had its letters on the end of rods called "typebars." The typebars hung in a circle. The roller which held the paper sat over this circle, and when a key was pressed, a typebar would swing up to hit the paper from underneath. If two typebars were near each other in the circle, they would tend to clash into each other when typed in succession. So, Sholes figured he had to take the most common letter pairs such as "TH" and make sure their typebars hung at safe distances.

He did this using a study of letter-pair frequency prepared by educator Amos Densmore, brother of James Densmore, who was Sholes' chief financial backer. The QWERTY keyboard itself was determined by the existing mechanical linkages of the typebars inside the machine to the keys on the outside. Sholes' solution did not eliminate the problem completely, but it was greatly reduced.

QWERTY's effect, by reducing those annoying clashes, was to speed up typing rather than slow it down

Answer 2

You mean like, why isn't it in sensible alphabetical order? The first typewriters were gimmicky multiple-lever arrangements and tended to jam if several keys were hit quickly. To minimize this the most frequently used letters were placed at a little distance from one another so there'd be less chance of such a jam-up. Then touch typing was developed and at the same time typewriters got more reliable, so that 50-60 words per minute was quite a reasonable speed. (I can do 75 wpm if I try, and I'm not a professional.) However, touch typing requires memorizing the keyboard so that you see you need to type "hurray!" and your fingers just go _zip_, without your having to do conscious control of each letter. Unfortunately, the keyboard they memorized was the established one which was originally designed to keep typewriter keys from jamming. Changing it would require re-training all the typists in the world, even though modern word processors don't strike keys against paper and can't jam. There have been proposals to replace the existing qwerty keyboard with a more efficient one, like the Dvorak keyboard, but all of them have come a cropper on the problem of retraining the millions of typists who know the qwerty keyboard by heart already and would cost an incredible amount (both money and time) to learn a completely different one.

Answer 3

Actually this design was set out many years ago by the ASDF society. (just kidding)

The QWERTY layout is currently the most popular keyboard configuration. It is named after the first six keys of the upper left hand row. It was developed in 1872 and laid out to slow typists down somewhat and so prevent "jamming" of mechanical typewriters. The DVORAK layout was proposed in 1932 as a faster and more efficient layout (Dvorak, 1943). This layout places the most frequently used keys on the home row. While it can be shown to be an improvement over the QWERTY layout, the magnitude of the advantages have not been shown sufficient to justify retrofitting keyboards and retraining typists. Thus, it currently has limited acceptance.

Answer 4

There is no person named "Qwerty" although that is what the keyboard is called after the first six letters on it.

The "Qwery" keyboard was arranged based on the home keys being those most frequently used and the next most common being next to them.

There have been studies indicating more efficiient keyboard layouts, even some with alphabetical order,.and some are much more efficient and fast when typists become accustomed to them, but the Qwerty has become the universal standard for English typewriters.

Answer 5

Keyboards adopted the key lay outs on typewriters and typewriters seems have problems then if using the alphabetical layout which has constant jamming that is why a person named Qwerty developed/designed a key layout which doesn't jam and It is being presently used..

Check out the word qwerty in your keyboard...

Answer 6

There are actually two different configurations of keyborads, neither of which are alphabetical. The most common is the 'qwerty' keyboard, so named because the first 6 letters spell qwerty, NOT because someone named Qwerty invented it.
