Arrangement of keys on keyboard is called                      ?

The correct answer is Qwerty because QWERTY is the universal, globally standard typographic layout used for Latin-script computer keyboards.

• Step 1 (Design History): Patented by Christopher Sholes in 1878 for mechanical typewriters, the layout strategically separated common sequential letter pairs to prevent mechanical type bars from clashing and jamming during rapid typing.


• Step 2 (Modern Application): The name is a literal reference to the first six letters reading from left to right on the top row of alphabetic keys: Q-W-E-R-T-Y.


• Incorrect Options:
  
  
  
  • Asdfg is incorrect because it simply copies the first five characters of the central home row sequence, rather than representing an officially classified layout standard.
  
  
  • Azerty is incorrect as a general answer because while AZERTY is a real layout variation customized for French-speaking regions, QWERTY remains the definitive, baseline global key arrangement design.
  
  
  • None is incorrect because Qwerty is the accurate technical descriptor.
