Why is the arrangement of computer keyboard letters QWERT'' instead of ABCD''?

Many people are confused about the alphabetical order of computer keyboards. B is not next to A, but P and Q, which should be connected, are on their own side, far away from each other. What is the reason? In fact, the original design concept of this keyboard is to let you play fast!

At present, the keyboard commonly used by the public is called "fast hoof keyboard", and the original text is "QWERTY". Has anyone found that this word looks a little familiar and unfamiliar, but it is actually a combination of the first row of letters on the keyboard? Please look at the following three lines of letters:

Q

W

E

rare

T

Y

U

I

O

P

A

S

D

F

G

H

J

K

L

Z

X

C

V

B

ordinary

M

The first typewriter appeared in 1868.

This is the arrangement order of all computer keyboard letters or English typewriter keyboard letters. Interested readers may wonder: Why do you want to arrange 26 letters in this random way? It is difficult to remember and master. The original keyboards were basically arranged in alphabetical order, but in order to prevent the typewriter from hitting too fast, the mechanical rods supporting the keyboards collided with each other and caused failures, so the positions of some letters were adjusted, forming today's appearance. It is said that the reason is this:

19 in the 1970s, Shoals company (Sholes

Company) was the largest typewriter manufacturer at that time. Because the mechanical technology was not perfect at that time, the keys rebounded slowly after being hit. Once the typist hits the keys too fast, the two keys are easily twisted together and have to be carefully separated by hand, which seriously affects the typing speed. To this end, the company often receives complaints from customers.

In order to solve this problem, designers and engineers have been racking their brains, because there is really no way to improve the rebound speed of keys. Later, a clever engineer suggested that on the one hand, typewriters twist keys slowly, on the other hand, typists type keys too fast. Since we can't increase the speed at which the keys pop up, why not try to slow down the typist's keystrokes? This is undoubtedly a new idea. There are many ways to slow down the typist's keystrokes. The easiest way is to disrupt the arrangement of 26 letters and put the more commonly used letters under clumsy fingers. For example, the letter "O" is the third most commonly used letter in English, but it is placed under the ring finger of the right hand. The letters "S" and "A", also commonly used letters, are used for the clumsy left hand ring finger and little finger. In the same way, unusual letters such as "V", "J" and "U" are handled with the most flexible index finger.

Thus, this "QWERTY" combination keyboard was born and gradually took shape. Later, due to the development of materials and technology, the speed of keys bouncing back is much faster than that of typists, but the alphabetical order of keyboards cannot be changed.

This arrangement really brings a lot of trouble to beginners in input. In fact, as early as 1936, some people noticed this problem and introduced a more ergonomic keyboard. Unfortunately, this keyboard died in World War II before it went on the market. Recently, a group actively promoted this keyboard named "Devzak", and perhaps in the near future, the new letter arrangement will be widely adopted.
