The answer of Statement 1 Speech technology is a small...

Question 8

Statement 1 Fitts' Law uses the formula movement time = a + b log2 (distance/size + 1) where a and b are empirically determined constants. Statement 2 Studies of keyboard operators have shown that, although the faster operators were up to twice as fast as the others, the slower ones made 10 times the errors.
A)Only Statement 1 is True
B)Only Statement 2 is True
C)Both statements are True
D)Both statements are False

Accepted Answer

Fitts' Law is accurately described in Statement 1, and Statement 2 reflects findings from studies on keyboard operators regarding speed and error rates.

Question 9

Statement 1 Recognition is easier than recall. Statement 2 The main strength of the Problem Space Framework as a model of human problem solving is that it allows ill-defined problems to be solved.
A)Only Statement 1 is True
B)Only Statement 2 is True
C)Both statements are True
D)Both statements are False

Accepted Answer

Recognition is generally easier than recall because it involves identifying information from a set of options, whereas recall requires retrieving information without cues. The Problem Space Framework does not specifically address solving ill-defined problems; it is more suited to well-defined problems.

Question 10

Statement 1 The fovea of the human eye is just behind the cornea. Statement 2 The blind spot of the eye is just under the lens.
A)Only Statement 1 is True
B)Only Statement 2 is True
C)Both statements are True
D)Both statements are False

Accepted Answer

The fovea is located in the retina, not just behind the cornea, and the blind spot is where the optic nerve exits the eye, not under the lens.

Question 11

The term human-computer interaction has only been in widespread use since the early
A)2000s
B)1950s
C)1970s
D)1980s

Accepted Answer

The term "human-computer interaction" became widely used in the 1980s, coinciding with the advent of personal computers and graphical user interfaces which necessitated a focus on the interaction between users and computers.

Question 12

Which of the following is a long-term individual difference?
A)Weight
B)Color
C)Sex
D)Height

Accepted Answer

Sex is considered a long-term individual difference because it is a biological characteristic that is generally fixed from birth and does not change over time, unlike weight or height which can vary, and color which is too ambiguous (could refer to skin, hair, etc., and can also change or be changed).

Question 13

Which of the following are important in the design focus of HCI?
A)Thinking of the user
B)Testing the HCI
C)Involving the users
D)All of the above

Accepted Answer

All of the options listed are crucial aspects of the design focus in Human-Computer Interaction (HCI). Thinking of the user ensures that the design is user-centric, testing the HCI is essential for usability and functionality, and involving the users in the design process helps in creating more effective and user-friendly interfaces.

Question 14

Which of the following are examples of paradigms for interaction?
A)Personal computing
B)Hypertext
C)Multi-modality
D)All of the above

Accepted Answer

All of the options listed (Personal computing, Hypertext, Multi-modality) are examples of paradigms for interaction, as they each represent different ways in which users can interact with computers or digital information.

Question 15

You receive an email message, and a flag immediately appears in your electronic mailbox to indicate that you have a new message. This is an example of:
A)Persistence
B)Guidance
C)Existence
D)None of the above

Accepted Answer

Persistence is the ability of a system to retain data even after the power has been turned off. In this case, the flag that appears in your electronic mailbox is an example of persistence because it retains the information that you have a new message even after you have closed the mailbox.

Question 16

If requirements are easily understandable and defined then which model is best suited?
A)Spiral model
B)Waterfall model
C)Prototyping model
D)None of the above

Accepted Answer

The Waterfall model is best suited for projects where requirements are easily understandable and well-defined. It follows a linear and sequential approach, making it efficient for projects with clear objectives and stable requirements.

Question 17

Which of these describes stepwise refinement?
A)Nicklaus Wirth described the first software engineering method as stepwise refinement
B)Stepwise refinement follows its existence from 1971
C)It is a top down approach
D)All of the mentioned

Accepted Answer

Stepwise refinement, as described by Niklaus Wirth, is indeed a method in software engineering that emphasizes a top-down approach, starting with a broad specification and breaking it down into more detailed parts iteratively. This concept has been around since 1971, making all the mentioned statements correct.

Question 18

What is followed by the design task?
A)Choosing specific classes, operations
B)Checking model's completeness
C)Following design task heuristics
D)All of the mentioned

Accepted Answer

All of the mentioned options are followed by the design task, including choosing specific classes and operations, checking the model's completeness, and following design task heuristics.

Question 19

Design phase is followed by ______ .
A)Coding
B)Testing
C)Maintenance
D)None of the above.

Accepted Answer

In the software development lifecycle, the design phase is typically followed by the coding (or implementation) phase, where the software design is translated into source code.

Question 20

Where is the prototyping model of software development well suited?
A)When requirements are well defined.
B)For projects with large development teams.
C)When a customer cannot define requirements clearly.
D)None of the above.

Accepted Answer

The prototyping model is particularly effective when customers do not have a clear idea of their requirements. It allows for the creation of a prototype that can be evaluated and refined based on customer feedback, leading to clearer requirements and a more satisfactory final product.
