Q11.
Which keyboard layout is the most widely used?

a.

DVORAK

b.

Alphabetic

c.

Chord

d.

QWERTY

Discuss
Answer: (d).QWERTY Explanation:The vast majority of keyboards have a QWERTY layout, which is named after the first six letters of the top row of alphabetical keys.
Q12.
Why have alternative keyboard designs not replaced the QWERTY layout?

a.

They are more expensive

b.

They are more complex

c.

They have not overcome the technological inertia of the QWERTY keyboard

d.

They are less ergonomic

Discuss
Answer: (c).They have not overcome the technological inertia of the QWERTY keyboard Explanation:Even though alternative designs may have some advantages over the QWERTY layout, they have not been widely adopted due to the vast technological inertia of the QWERTY keyboard.
Q13.
How does the French keyboard layout differ from the standard layout?

a.

It has a larger number of keys

b.

It uses a chord layout

c.

It starts with the letters AZERTY

d.

It has the letters arranged alphabetically

Discuss
Answer: (c).It starts with the letters AZERTY Explanation:The French layout differs from the QWERTY keyboard as the top line starts with the letters AZERTY, not QWERTY.
Q14.
What is one variation among QWERTY keyboards?

a.

The size of the keys

b.

The arrangement of the alphabetical keys

c.

The placement of non-alphanumeric keys

d.

The color of the keys

Discuss
Answer: (c).The placement of non-alphanumeric keys Explanation:Non-alphanumeric keys vary between keyboards. For example, there is a difference between key assignments on British and American keyboards, such as the placement of the pound and dollar signs. Additionally, brackets, backslashes and suchlike can also be differently placed.
Q15.
Why was the QWERTY keyboard layout originally designed in its current format?

a.

To make it easier to type common words

b.

To prevent arms of mechanical typewriters from jamming

c.

To make it easier to learn to type

d.

To fit more keys on the keyboard

Discuss
Answer: (b).To prevent arms of mechanical typewriters from jamming Explanation:The QWERTY keyboard layout was originally designed to prevent the arms of mechanical typewriters from jamming. Common combinations of consecutive letters were placed at different ends of the keyboard so the arms would usually move from alternate sides.
Q16.
Why has the QWERTY keyboard layout remained dominant despite no longer being subject to its original mechanical constraints?

a.

It's more efficient for typing

b.

The cost and effort to retrain typists and replace keyboards is too high

c.

It's easier to manufacture

d.

It's more ergonomic

Discuss
Answer: (b).The cost and effort to retrain typists and replace keyboards is too high Explanation:The QWERTY keyboard remains dominant mainly due to social reasons. The cost and effort of retraining typists and replacing keyboards would be immense. Management is often not prepared to accept the initial decrease in productivity that would result from retraining.
Q17.
What is the advantage of an alphabetic keyboard layout?

a.

It increases typing speed for trained typists

b.

It looks simpler to use than the QWERTY layout

c.

It's more ergonomic than other layouts

d.

It's more efficient for typing

Discuss
Answer: (b).It looks simpler to use than the QWERTY layout Explanation:An alphabetic keyboard layout might appear simpler to use than the QWERTY one. However, studies have shown that it doesn't necessarily make typing faster for properly trained typists or even for novice or occasional users.
Q18.
Why might alphabetic keyboards be used in pocket electronic personal organizers?

a.

To allow for touch-typing

b.

To make the device look more advanced

c.

To dissuade people from attempting to use their touch-typing skills

d.

To make the device smaller

Discuss
Answer: (c).To dissuade people from attempting to use their touch-typing skills Explanation:Alphabetic keyboards might be used in pocket electronic personal organizers to dissuade people from attempting to use their touch-typing skills on a very small keyboard. This could help avoid criticisms of difficulty of use.
Q19.
What is the primary goal of the DVORAK keyboard layout?

a.

To prioritize right-handed people

b.

To increase typing speed and reduce user fatigue

c.

To decrease the number of keystrokes needed

d.

To allow for a larger number of keys on the keyboard

Discuss
Answer: (b).To increase typing speed and reduce user fatigue Explanation:The DVORAK keyboard is designed to help people reach faster typing speeds and reduce user fatigue. The layout of keys is such that the majority of keystrokes alternate between hands and most commonly used keys are kept on the home row, reducing the need to stretch fingers far.
Q20.
How does the DVORAK keyboard layout accommodate right-handed people?

a.

By placing most common keys on the right side

b.

By making 56% of keystrokes with the right hand

c.

By placing number keys on the right side

d.

By placing function keys on the right side

Discuss
Answer: (b).By making 56% of keystrokes with the right hand Explanation:The DVORAK keyboard layout is biased towards right-handed people, with 56% of keystrokes being made with the right hand.
