why the keyboard's alphabets are not in line wise?

Question

on keyboard english alphabets are like this
(qwertyuiop,asdfghjkl,zxcvbnm) but isaid why are not likethis(abcdefghijklmnopqrstuvwxyz)

Answer 1

The layout of the computer keyboard was borrowed from the typewriter because there had been millions of people using typewriter when the computer keyboard was designed. To minimize the re-training efforts, most of the keys on the keyboard were at the same position as they did on the typewriter.

When the Remington typewriter was designed in 1877, everything was mechanic. Each character was attached to a type bar. The major problem confronting the designers was that different type bars got stuck with each other when people typing fast. The keys were then arranged in such a way that most frequently used keys were far apart.

And this -
As already stated in other answers, the Qwerty layout, named after the six letters on the left of the top row, was designed around 1878 to slow down typing and stop the mechanical keys from jamming on typewriters.

Electronic keyboards have no mechanical speed limitations, so why do we not have alphabetical layouts on keyboards today? There are probably two main reasons for this: First, resistance to change (example: lack of acceptance of good homerow-oriented keyboards, like Dvorak, from 1936), and second, alphabetical layouts are probably no faster than Qwerty.

Typing speed depends on the frequency of letters and key sequences. A complete set of letter and sequence statistics may be found at: http://www.xpertkeyboard.com... Typing is fastest when sequences are struck by opposite hands, even when reaching across rows. The mind and hand can "preset" key sequences for maximum speed. Touch typing can help overcome speed limitations from awkward key sequences, but few keyboard users have those skills.

Most words in English and other languages interleave vowels (v) and consonants (c). That is, letter patterns are typically: vcvccvc, etc. An alphabetic keyboard forces vowels and frequent consonants to appear in particular locations on both left and right sides of the keyboard. Vowels and consonants cannot be separated on different sides of the keyboard, as needed for maximum speed.

Although alphabetic keyboards have been patented as early as 1984 and as late as 2000, and are available on the marketplace, they have not made a serious challenge to the standard Qwerty layout from 1878.

Answer 2

The letters strategically placed so that the letters you use most often are placed in the center of the keyboard and letters which are often followed by the same letters are placed near each other. It is too speed up typing. Once you get the hang of it, it is a lot quicker than it would be to type with letters in alphabetical order.

Answer 3

Old typewriters can get jammed up if you type too fast. Christopher Sholes created the QWERTY keyboard layout which separated common key sequences so their hammers weren't adjacent to each other and wouldn't jam when typed in quick succession.

Answer 4

i heard that back in the day when the typewriter was invented, the keys in the top row were placed so that when the sales person was pitching this new piece of equipment he could type out the word typewriter using the top row of letters quickly....more impressive than hunting and pecking when you are trying to sell a product....
