About 150 years ago, all papers and letters were handwritten with a pen and ink, and about one or two words had to be put in the ink bottle, making writing very slow and easy to get dirty. .

Then a typewriter was born. The first typewriter was made of metal so it was heavy and had a mechanism that worked a bit like a piano, meaning that when you pressed a key, a lever bounced, causing the hammer at the top to type into the string. and make sounds.


Similarly, at the tip of the typewriter keys are hammers that print the letters. When you press the key with the letter A, the hammer’s hammer heads on the paper and prints the letter A, and the paper inches a little to the left so that the second hammer will type in the space immediately to the right of the A. so you can type a whole word, and if you type a lot, you will get the whole book.

The first typewriter had the same alphabetical order as in the alphabet. The problem is that if you type quickly, two keys side by side are very susceptible, especially if those keys are next to each other. Rearranging the keys reduces the chance that the keys will get stuck.

The American inventor named Christopher Sholes was the most successful when it came to reducing typewriter keys. He tried many arrangements and the best one was similar to the keyboard in the QWERTY order we use today.

Mr. Sholes sold the 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.

About 100 years later, so many people typed in the text that it became a professional profession around the world. They use the QWERTY keyboard so familiar that people can hardly change the habit of using the keyboard in a different arrangement.

Besides the QWERTY keyboard, a number of other keyboards were invented and considered easier to learn than the QWERTY keyboard. However, none of them is strong enough to defeat QWERTY.

QWERTY was invented to use the English alphabet. Other languages ​​use other keyboards, such as AZERTY for French, QWERTZ for German, or QZERTY for Italian. You can also see a keyboard used for Indian, Thai, Japanese, Korean or Chinese.
