Why do the 26 English letters on the computer s keyboard have to be broken up?

1.The letters are sorted by how often they are used. You can take a look at the story of the origin of its sorting.

This is the order in which all the computer keyboard letters or English typewriter keyboard letters are arranged.

Interested readers may wonder: why such an irregular arrangement of 26 letters? It's hard to memorize and hard to master. The reason for this is said to be this:

In the 70s of the 19th century, Shores was the largest manufacturer of typewriters at that time. Because the mechanical process is not perfect enough at that time, the rebound speed of the word key after hitting is slower, once the typist hits the key too fast, it is easy to occur the phenomenon that the two word keys are twisted together, and they must be separated very carefully by hand, thus seriously affecting the typing speed. For this reason, the company often receives complaints from customers.

To solve this problem, designers and engineers struggled with their brains. Later, a clever engineer suggested that the reason for the typewriter's twisting was that the word keys bounced back slowly, and on the other hand, the typist was too fast.

Since we can't increase the bounce speed, why not find a way to slow down the typing speed?

This is undoubtedly a new way of thinking. There are many ways to slow down a typist, but the easiest way is to shuffle the order of the 26 letters, placing the more commonly used letters, such as letters, under awkward fingers"o"、"s"、"a"It is used very frequently, but it is struck with the most clumsy right ring finger, left ring finger and left little finger. Less frequent use"v"、"j"、"u"and other letters, but the most flexible index finger is responsible.

As a result, this kind"qwerty"The keyboard was born and gradually finalized.

Later, due to the development of material technology, the speed of the word key bounce back was much greater than the speed of the typist's keystroke, but the keyboard alphabetical order could not be changed. So far, there have been many more rational alphabetical design schemes, but none of them can be generalized, which shows how powerful the customary forces of society are. 2.

In 1860, at a newspaper office in Milwaukee, Christopher? It was here that Shores took up his job, and as a person who needed to report on the war on a daily basis, the typewriter was already taking shape by that era. Based on his impressions, Shoers built a machine that could help him complete the task more quickly.

Since the original production was arranged in alphabetical order, Shaws felt that it was not as easy to use as he thought. Later, I modified it, quoted the classics, and found out that the keyboard format we use now starts with: q,w,e,r,t......Arrange.

You'll have to ask the inventor of the keyboard, but one thing is for sure, it's so easy to use.
