Alphabetical order on keyboard It's not ABCDE. But QWERT Copyright image, no permission to reprint So, do you know why the keyboard on the computer Why not arrange them in the order of the 26 letters we have learned? What is the purpose of this disruption? Let’s take a look at the secret below! It turns out that the layout of a computer keyboard is designed to slow down your typing speed. Let me put it this way. As early as the 1870s, typing machines were all mechanical structures, and the letters were 26 letters arranged in order. However, the mechanical technology level at that time was not enough, and the typists typed too fast, which caused the keys to rebound slowly and get stuck easily, which in turn affected the progress of the work. Copyright image, no permission to reprint To this end, the letters on the keyboard can only be shuffled to give some keys time to bounce back, and the typist's speed should be increased as much as possible. Later, with the arrival of new technology, although the letter keys will not get stuck, the QWERT key typing habit has been formed and has continued.
