...... To address this, Sholes had an ingenious idea.
He discovered that many English words contained combinations
of letters next to each other in the alphabet, for instance
ABBey, DEFEct, HIGh, etc.,which occurred frequently.
With the help of a teacher
called Amos Desmore, Sholes determined the combinations
that occurred most frequently, split them and placed the
component letters far away on the keyboard of his machine.
And this is how the QWERTY layout was born.
(The layout is referred to as “QWERTY” because of
the arrangement of the keys in the upper row).
As a result of this rearrangement, the keys that were
used most frequently were not as easily accessible
to the typist. Thus, the QWERTY layout effectively
reduced the speed at which human users could type,
thereby preventing their jamming the mechanism too often.....
