This article is about why the keyboards in computers are not arranged in alphabetical order. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Reasons: 1, so that the speed of the keystroke is not too fast, so as to avoid the keyboard "stuck key"; 2, if installed according to the order of ABCD, when the typist typing speed is too fast, the long pole and hammer of the two adjacent letters may be stuck together, resulting in a sticking accident.

The operating environment of this tutorial: windows10 system, Dell G3 computer.

Scholes arranges the letters out of order in order not to hit the key too fast, so as to avoid the occurrence of "stuck key" failure.

Reason:

At the beginning, Scholes installed the keyboard alphabetical keys in alphabetical order, that is, the alphabetical order in the upper-left corner of the keyboard was "ABCDEF".

But he soon discovered that when the typist typed a little faster, the long poles and hammers of the two adjacent letters might get stuck together, resulting in a "stuck key" failure.

To solve this problem, Scholes asked his brother-in-law, a mathematician and school teacher for help. The mathematician suggested that he separate the most commonly used concatenated letters of the English letters on the keyboard to avoid failure.

Scholes gladly adopted his brother-in-law's solution, arranging the letters out of order, resulting in a "QWERTY" layout.

Common keyboard layout classification

1. "QWERTY" keyboard

In 1868, American typesetter Christopher Larsen Scholes (Christopher Latham Sholes) obtained the patent for typewriter model and obtained the right to operate it.

He designed the general keyboard layout scheme, the "QWERTY" keyboard, a few years later.

2. "DVORAK" keyboard

Due to the emergence of blind typing technology, the keystroke is fast enough to meet the needs of daily work. However, 60 years later (1934), a Washington man named Dvorak invented a new arrangement to enable the left and right hands to type more words alternately. This keyboard can shorten the training cycle 1 / 2 time and increase the average speed by 35%.

3. "MALT" keyboard

More reasonable and efficient than the DVORAK keyboard is the MALT keyboard invented by Lillian Malt.

The MALT keyboard has changed the staggered line of keys and made more use of the thumb, making the "Backspace" and other keys away from the center of the keyboard easier to reach.

But MALT keyboards require special hardware to install on computers, so they are not widely used.
