KNOW WHY "ABCD" KEYBOARD IS NOT USED !!

QWERTY refers to the arrangement of keys on a standard English computer keyboard or typewriter. The name derives from the first six characters on the top alphabetic line of the keyboard.You might be wondering why ABCD arrangements of keys is not used on keyboard.We will discuss the reason behind this in this article.

The arrangement of characters on a QWERTY keyboard was designed in 1868 by Christopher Sholes, the inventor of the typewriter.When it was first invented, they had keys arranged in an alphabetical order, until configuration was desired over convention.But people typed so fast that mechanical character arm of typewriter got tangled up and it needed to be rectified everytime. So, keys were randomly positioned to actually slow down the speed of typing and preventing the key jams. 

The researchers then struggled for the next five years to perfect this invention, making many trial-and-error rearrangements of the original machine’s alphabetical key arrangement.They came up with QWERTY keyboard arrangements.

Contrary to popular belief, the QWERTY layout was not designed to slow the typist down, but rather to speed up typing by preventing jams. Indeed, there is evidence that, aside from the issue of jamming, placing often-used keys farther apart increases typing speed, because it encourages alternation between the hands.
