Q31.
What is one of the main challenges of handwriting recognition technology?

a.

It is expensive to implement

b.

It is slow to process handwritten text

c.

It struggles with individual differences in handwriting

d.

It can only recognize handwriting in certain languages

Discuss
Answer: (c).It struggles with individual differences in handwriting Explanation:One of the main challenges of handwriting recognition technology is the vast individual differences in handwriting. This makes the recognition process more difficult, as the technology must capture the stroke information and not just the final character shape.
Q32.
Why are pen-based systems attractive for mobile computing and pocket organizers?

a.

They are lighter than keyboard-based systems

b.

They allow for text and diagram input without needing to change input methods

c.

They have better battery life than keyboard-based systems

d.

They are cheaper than keyboard-based systems

Discuss
Answer: (b).They allow for text and diagram input without needing to change input methods Explanation:Pen-based systems are attractive for mobile computing and pocket organizers because they allow for both text and diagram input without needing to switch input methods. This makes them suitable for tasks such as taking notes, jotting down and sketching ideas, as well as maintaining diaries, address books, and organizers.
Q33.
What does the adoption of a different input device like a pen-based system suggest about interface designs?

a.

It requires the use of larger screens

b.

It opens up a range of alternative interface designs and possibilities for interaction

c.

It necessitates the use of more advanced hardware

d.

It limits the range of tasks that can be performed

Discuss
Answer: (b).It opens up a range of alternative interface designs and possibilities for interaction Explanation:Adopting a different input device like a pen-based system can open up a host of alternative interface designs and different possibilities for interaction. For example, systems can implement gesture recognition as a way to interact with the system, such as drawing a line through a word to delete it.
Q34.
What is speech recognition?

a.

A technology that translates spoken words into written text.

b.

A method to improve public speaking skills.

c.

A tool for diagnosing speech disorders.

d.

A method for determining the emotional state of a speaker.

Discuss
Answer: (a).A technology that translates spoken words into written text. Explanation:Speech recognition is a technology that translates spoken words into written text. It is primarily used as a form of text entry and command issuance for devices and software.
Q35.
What is one of the main challenges of speech recognition technology?

a.

It can only recognize a small number of words.

b.

It struggles to understand strong accents, emotions, and background noise.

c.

It cannot recognize commands, only natural language speech.

d.

It requires a very fast internet connection to work properly.

Discuss
Answer: (b).It struggles to understand strong accents, emotions, and background noise. Explanation:One of the main challenges of speech recognition technology is its struggle to understand variations in speech due to strong accents, emotional inflections, or background noise. Each person's speech is unique, which means the system often needs to be trained and tuned to each new speaker to maintain its performance.
Q36.
In what kind of environments could the widespread use of speech recognition technology create problems?

a.

In quiet libraries

b.

In open-plan offices

c.

In private offices

d.

In outdoor spaces

Discuss
Answer: (b).In open-plan offices Explanation:In open-plan offices, widespread use of speech recognition technology could lead to a significant increase in noise levels, which could cause problems for the technology itself and for other people working in the office. It could also compromise confidentiality as spoken commands or conversations could be overheard by others.
Q37.
Which of the following is a current successful application area for speech recognition technology?

a.

Private counseling sessions

b.

Music composition

c.

Access for the disabled

d.

Video game playing

Discuss
Answer: (c).Access for the disabled Explanation:Speech recognition technology has found success in niche markets, including providing access for disabled individuals. This technology can be a great aid for people who may have difficulty using traditional input methods, such as a keyboard or mouse.
Q38.
What is a mouse in terms of computer hardware?

a.

An input device that allows you to manipulate objects on your computer screen.

b.

A software program that helps you navigate your computer.

c.

A hardware component that helps to speed up your computer's performance.

d.

A device that helps to cool down your computer.

Discuss
Answer: (a).An input device that allows you to manipulate objects on your computer screen. Explanation:In computer hardware terms, a mouse is an input device that allows the user to manipulate objects on the screen. You can use it to point, click, select, and move objects, or initiate actions in a software environment.
Q39.
What is the function of a potentiometer inside a traditional ball mouse?

a.

It adjusts the weight of the mouse to the user's preference.

b.

It regulates the power supply to the mouse.

c.

It translates the rotation of the ball into horizontal and vertical motion.

d.

It determines the click speed of the mouse buttons.

Discuss
Answer: (c).It translates the rotation of the ball into horizontal and vertical motion. Explanation:In a traditional ball mouse, a potentiometer is a component that helps to detect and translate the rotation of the ball into horizontal and vertical motion. As the mouse moves, the ball inside it rotates. This rotation is detected by small rollers that adjust the values of the potentiometers, which can then be used to determine the mouse's movement.
Q40.
Why is a 'mouse' called so?

a.

Because it looks like a real mouse with its body being the hardware and the wire acting as the tail.

b.

Because it moves quickly and accurately like a real mouse.

c.

Because it was invented by a person with the surname Mouse.

d.

Because the initial prototype was tested on mice.

Discuss
Answer: (a).Because it looks like a real mouse with its body being the hardware and the wire acting as the tail. Explanation:The term "mouse" for the device comes from its resemblance to the rodent. The main part of the device represents the body of a mouse, and the wire that connects it to the computer represents the tail. This resemblance led to the device being nicknamed a "mouse."
