The QWERTY keyboard, which appeared decades earlier than the computer. In 1714, various forms of typewriters were invented, at the time the printer needed keyboards in alphabetical order, if typing too fast, certain key combinations are easy to have card key problems, so his brother-in-law mathematician suggested, He placed the most commonly used letters in the opposite direction, slowing down the keystrokes to avoid card keys, and eventually formed the "QWERTY" layout. But what really made this layout famous was a typing competition held in Cincinnati, USA, on July 25, 1888. During the game, McGuire (Frank McGurrin), a court stenographer from Salt Lake City, used the “QWERTY” layout typewriter and blind play method to win the championship and $500 prize by absolute advantage. The Sydney Powerhouse Museum, a series that shows the development of printers and computers, also witnessed little change in keyboards.
