Why computer keyboards use the QWERTY layout instead of ABCD
- •Early typewriter mechanical arms used to collide and jam when typists typed too fast.
- •Inventor Christopher Latham Sholes designed the QWERTY layout to solve this technical problem.
- •Frequently used letter combinations were separated to prevent mechanical jamming.
- •The layout became a universal standard and continues to be used today due to habit and convenience.

The QWERTY layout was invented in the 19th century to solve mechanical jamming issues in early typewriters. When typists worked too quickly on alphabetical keyboards, the metal arms of adjacent letters collided with each other.
The QWERTY layout was designed by an American inventor named Christopher Latham Sholes. Typewriter manufacturers began officially adopting this system in the 1870s.
Christopher Latham Sholes separated frequently occurring letter combinations in English, such as TH, HE, IN, and ER, placing them in different locations on the keyboard. This spatial separation prevented the mechanical arms from striking each other and jamming during rapid typing.
