Incorrect Statement: John Douglas is the inventor of QWERTY keyboard layout.
Explanation:
The QWERTY keyboard layout is one of the most commonly used keyboard layouts for English language keyboards. It is named after the first six letters in the top row of the keyboard. However, John Douglas was not the inventor of the QWERTY keyboard layout.
Background Information:
To understand why option 'D' is incorrect, it is important to know the history of the QWERTY keyboard layout. The QWERTY layout was designed in the 1860s by Christopher Latham Sholes, a newspaper editor and printer. Sholes invented the typewriter and developed the QWERTY keyboard layout to prevent jamming of the mechanical keys on early typewriters.
Key Points:
Here are the key points to support the explanation:
1. Christopher Latham Sholes: Christopher Latham Sholes was an American inventor who is credited with inventing the typewriter. He developed the QWERTY keyboard layout to overcome the problem of key jamming on early typewriters.
2. QWERTY Keyboard Layout: The QWERTY keyboard layout was designed to place commonly used letters apart from each other to reduce the likelihood of jamming. The layout was patented by Sholes in 1868.
3. John Douglas: John Douglas is not associated with the invention or design of the QWERTY keyboard layout. There is no historical evidence or recognition attributing the QWERTY layout to him.
Conclusion:
Based on historical records and evidence, it can be concluded that John Douglas is not the inventor of the QWERTY keyboard layout. The correct inventor of the QWERTY layout is Christopher Latham Sholes, who developed it in the 1860s to prevent key jamming on early typewriters.
