Why are some keyboards in alphabetical order?

The first machine had the letter keys in alphabetical order. The trouble was that if you hit two keys quickly the levers would jam. Jams were most likely when the two keys were close together on the keyboard. Rearranging the letters could reduce jams.

Are alphabetical keyboards faster?

Even though they could only type about one letter per second, the speed achieved on the qwerty keyboard was 67% greater than the speed reached with the alphabetic keyboards and 83% greater than that reached with the random keyboard.

Why keyboard layout is not arranged alphabetically?

The reason dates back to the time of manual typewriters. When first invented , they had keys arranged in an alphabetical order, but people typed so fast that the mechanical character arms got tangled up. So the keys were randomly positioned to actually slow down typing and prevent key jams.

Is ABC or QWERTY better?

Cognitively, an ABC layout is easier for students to learn than QWERTY if they already know the alphabet. Physically, there is no advantage for using a QWERTY onscreen keyboard layout compared to an ABC onscreen layout.
