5. Differentiate between the QWERTY and DVORAK keyboard layouts.
Ans. QWERTY: It is the most efficiently designed, standard keyboard layout used in countries that use Latin-based alphabets.
This layout is followed in most of the PCs, laptops, virtual keyboards, smart TV, smartphones etc. The name ‘QWERTY’
comes from the first six alphabets on the left side of the keyboard. The earliest typewriter keyboards, with QWERTY layout
was designed by an American inventor—Christopher Latham Sholes, to reduce the jamming of the type bars and also
speeding up the typing process.
DVORAK: This layout was also designed for Latin-based alphabets and as an alternative to the QWERTY layout. It was
created by August Dvorak in the 1930’s. The main advantage of this layout is that, it requires less movement of fingers, thus
reducing the typing errors which in turn will help in increasing the typing speed.

1. An English teacher conducted an online essay competition with a time limit of half an hour. Priya participated in the
competition by typing 100 words in 10 minutes, with mistakes in 5 words. What will be her:
a. Gross and Net typing speed
b. Accuracy percentage
Ans. a. Gross and Net Typing Speed
Gross Typing Speed = (Words without errors + Words with errors) / Time spent in minutes
= 100/10
= 10 WPM
Net Typing Speed = WPM - (Words with errors / Time spent in minutes)
= 10 – (5/10)
= 9.5 WPM
b. Accuracy % = 100% – ((Words with errors × 100%) / Total number of words)
= 100 – ((5 *100)/100)
= 100 – 5
= 95%
