About 150 years ago, all papers and letters were handwritten with ink pens, and every 1 to 2 words people had to tap on ink bottles making writing very slow and easy to dirty. .
Then the typewriter came into being. The first typewriters made of metal should be very heavy and have a mechanism that works a bit like a piano, that is, when you press a key, a bouncing lever causes the hammer at the top to tap on the string. and create sound.
Similarly, at the top of the typewriter keys are hammers that print letters. When you press the key with the letter A, the key of that key knocks on the paper and prints A, and the paper moves a little to the left so that the second hammer will type in the blank right to the letter A. So you will type enough one word, and typing a lot will get the whole book.
The first typewriter has the same alphabetical order as in the alphabet. The problem is that if you type fast, the two keys next to each other are easy to catch, especially if those two keys are standing side by side. Rearranging the keys will reduce the likelihood of the keys being stuck.
The American inventor named Christopher Sholes was the most successful when he came up with a way to reduce the typography. He tried many sort of arrangements and the best way is similar to the QWERTY keyboard that we use today.
Mr. Sholes sold this invention to Remington Company in the US. In the 1870s, the Remington company produced and sold the first typewriters for commercial purposes. These machines have a QWERTY keyboard.
After about 100 years, many people did the typing work so much that it became a professional profession all over the world. They use the familiar QWERTY keyboard to the extent that people can hardly change the habit of using the keyboard in a different way.
Besides the QWERTY keyboard, some other keyboards were also invented and considered to be easier to learn than QWERTY keyboards. However, none of them are powerful enough to defeat QWERTY.
QWERTY was invented to use for the English alphabet. Some other languages use other keyboards, such as AZERTY for French, QWERTZ for German, or QZERTY for Italian. You can also see a keyboard for Indian, Thai, Japanese, Korean or Chinese.
