Q21.
What is the main feature of ergonomic keyboard designs?

a.

Concave plane or split keys for each hand

b.

Additional function keys

c.

Lighter key resistance

d.

Integration of a touchpad

Discuss
Answer: (a).Concave plane or split keys for each hand Explanation:More ergonomic keyboard designs have altered the basic tilted planar base of the keyboard. Moderate designs curve the plane of the keyboard, making it concave, while more extreme ones split the keys into those for the left and right hand and curve both halves separately. These designs are meant to aid comfort and reduce Repetitive Strain Injury (RSI) by minimizing effort.
Q22.
What is a unique feature of chord keyboards?

a.

They have a large number of keys

b.

Letters are produced by pressing multiple keys at once

c.

They have a QWERTY layout

d.

They require two hands to operate

Discuss
Answer: (b).Letters are produced by pressing multiple keys at once Explanation:Chord keyboards are different from normal alphanumeric keyboards. They usually have only a few keys, and letters are produced by pressing one or more of the keys at once.
Q23.
Why can chord keyboards be beneficial?

a.

They allow for more accurate typing

b.

They are extremely compact and can be used for one-handed operation

c.

They are more familiar to most users

d.

They require less learning time

Discuss
Answer: (b).They are extremely compact and can be used for one-handed operation Explanation:Chord keyboards have several advantages. They are extremely compact, which makes them a good choice for use in cramped conditions or when only one-handed operation is possible. Despite their compact size, they do not increase the difficulty of use as much as simply reducing the size of a conventional keyboard would.
Q24.
What is a potential hurdle for the widespread adoption of chord keyboards?

a.

Their high cost

b.

The difficulty of learning to use them

c.

The fact that they can only be used with one hand

d.

Social resistance to using them

Discuss
Answer: (d).Social resistance to using them Explanation:While chord keyboards have many advantages, social resistance to using them is still high. This resistance, combined with a lack of familiarity with the chord keyboard layout, makes it unlikely that these keyboards will become a mainstream form of text entry.
Q25.
Where are chord keyboards particularly useful?

a.

In graphic design

b.

In courtroom stenography and the wearables market

c.

In gaming

d.

In data entry

Discuss
Answer: (b).In courtroom stenography and the wearables market Explanation:Chord keyboards are especially beneficial in certain niche areas. Courtroom stenographers use a special form of two-handed chord keyboard to enter text at the speed of speech. The compact size and one-handed operation of chord keyboards might also find a place in the growing wearables market.
Q26.
What is the main challenge of text input using a phone pad?

a.

The keys are too small

b.

There are only digits, not a full alphanumeric keyboard

c.

It is difficult to press the correct keys

d.

The phone pad is not responsive

Discuss
Answer: (b).There are only digits, not a full alphanumeric keyboard Explanation:The main challenge with phone pads is that they only contain digits from 0-9, and do not have a full alphanumeric keyboard. Therefore, entering text requires multiple presses of a key to cycle through the associated letters.
Q27.
How is the challenge of text input using a phone pad typically addressed?

a.

By connecting an external keyboard to the phone

b.

By pressing numeric keys multiple times to represent different letters

c.

By using voice-to-text technology

d.

By pressing two or more keys simultaneously to produce different letters

Discuss
Answer: (b).By pressing numeric keys multiple times to represent different letters Explanation:To overcome the limitation of the phone pad, the numeric keys are usually pressed several times to cycle through associated letters. For example, pressing the '3' key once could produce a 'd', pressing it twice an 'e', and pressing it three times an 'f'.
Q28.
What does the T9 algorithm do?

a.

It automatically corrects typos

b.

It translates text to voice

c.

It uses a dictionary to disambiguate words by typing relevant letters once

d.

It suggests words based on the first few letters typed

Discuss
Answer: (c).It uses a dictionary to disambiguate words by typing relevant letters once Explanation:The T9 algorithm uses a large dictionary to disambiguate words by simply typing the relevant letters once. It maps numeric sequences to words in its dictionary. When ambiguities exist, such as '26' which could be 'am' or 'an', the phone provides a series of options to choose from.
Q29.
What method do experienced mobile phone users often use to speed up text entry?

a.

They use a special code to represent common words

b.

They use a highly developed shorthand to reduce the number of keystrokes

c.

They use an external keyboard

d.

They use voice-to-text technology

Discuss
Answer: (b).They use a highly developed shorthand to reduce the number of keystrokes Explanation:Experienced mobile phone users often develop a shorthand to reduce the number of keystrokes needed to type messages. This could include abbreviations, acronyms, or other forms of textual shorthand.
Q30.
What is handwriting recognition?

a.

It is a technology that can identify and convert handwritten text into machine-readable characters.

b.

It is a method of text entry where you write words on a screen using your finger.

c.

It is a technology that can read and translate written documents into another language.

d.

It is a tool that helps you improve your handwriting.

Discuss
Answer: (a).It is a technology that can identify and convert handwritten text into machine-readable characters. Explanation:Handwriting recognition is a technology that can identify and convert handwritten text into machine-readable characters. This technology captures the stroke information during the writing process, not just the final character shape, making it easier to recognize letters and words.
