Q61.
What is the primary focus of the Keystroke-Level Model (KLM)?

a.

Understanding complex problem-solving activities

b.

Analyzing user feedback and preferences

c.

Predicting user performance for unit tasks

d.

Exploring user interactions with diagrams

Discuss
Answer: (c).Predicting user performance for unit tasks Explanation:The Keystroke-Level Model is aimed at predicting user performance for unit tasks and simple command sequences.
Q62.
In the Keystroke-Level Model, how is the execution phase of a task divided?

a.

Task decomposition and system response

b.

Mental preparation and physical execution

c.

User input and system output

d.

Problem-solving and goal achievement

Discuss
Answer: (b).Mental preparation and physical execution Explanation:The execution phase of a task in KLM is divided into mental preparation for physical actions and the actual physical execution using the system's facilities.
Q63.
Which operator in KLM involves moving the mouse (or similar device) to a target?

a.

K - Keystroking

b.

B - Pressing a mouse button

c.

P - Pointing

d.

H - Homing

Discuss
Answer: (c).P - Pointing Explanation:The P operator in KLM represents pointing, which involves moving the mouse or a similar device to a target.
Q64.
What does the model predict for the total time taken during the execution phase of a task?

a.

Time taken for mental preparation

b.

Time taken for user feedback

c.

Sum of component times for physical motor operators

d.

Sum of system response times

Discuss
Answer: (c).Sum of component times for physical motor operators Explanation:The total time taken during the execution phase is predicted by summing up the component times for each of the physical motor operators.
Q65.
Which operator in KLM represents mentally preparing for a physical action?

a.

K - Keystroking

b.

M - Mentally preparing

c.

H - Homing

d.

B - Pressing a mouse button

Discuss
Answer: (b).M - Mentally preparing Explanation:The M operator in KLM represents mentally preparing for a physical action.

a.

Time taken for pressing a mouse button

b.

Time taken for mentally preparing for a physical action

c.

Time taken for keystrokes

d.

Time taken for pointing

Discuss
Answer: (c).Time taken for keystrokes Explanation:tK represents the time taken for keystrokes in the KLM calculations.
Q67.
What is the purpose of the response time operator (R) in the Keystroke-Level Model?

a.

To measure the user's reaction time

b.

To estimate the overall task duration

c.

To indicate system performance

d.

To adjust the user's mental preparation time

Discuss
Answer: (b).To estimate the overall task duration Explanation:The response time operator (R) in KLM is used to estimate the overall duration of the task execution phase, including any system response time.
Q68.
When might the response time operator (R) be ignored?

a.

When the user is performing complex actions

b.

When the user is not waiting for a system response

c.

When the user is switching between applications

d.

When the user is using a search and replace feature

Discuss
Answer: (b).When the user is not waiting for a system response Explanation:The response time operator (R) may be ignored if the user does not have to wait for the system's response.
Q69.
What is the primary difference between KLM and GOMS models?

a.

KLM focuses on mental activities, while GOMS focuses on physical actions

b.

KLM is a high-level model, while GOMS is a low-level model

c.

KLM uses physical motor operators, while GOMS uses cognitive operators

d.

KLM assumes high-level mental activity, while GOMS assumes expert behavior

Discuss
Answer: (c).KLM uses physical motor operators, while GOMS uses cognitive operators Explanation:KLM uses physical motor operators to predict user performance, while GOMS uses cognitive operators to model user behavior.
Q70.
In the context of KLM, how does the model predict the time taken for multiple keystrokes?

a.

By summing up the individual keystroke times

b.

By multiplying the keystroke time by the number of keystrokes

c.

By averaging the keystroke times

d.

By subtracting the keystroke times from each other

Discuss
Answer: (a).By summing up the individual keystroke times Explanation:The model predicts the time taken for multiple keystrokes by summing up the individual keystroke times.
