A panel of keys that operates a computer or typewriter is called a keyboard. It plays a huge role in a computer because it plays the role of the input device. Christopher Sholes invented the first practical typewriter and introduced the keyboard layout that is familiar today in the year July 1, 1874.
The hydraulis was the world’s first keyboard instrument. The CTRL key is the most important key in a keyboard. The first keyboard had the letter keys in alphabetical order. However, this caused slow typing, and therefore, it had been rearranged in such a way that the person typing could type faster.
