Q81.
In the context of UIMS, what is the role of the dialog control component?

a.

It manages the appearance of the user interface.

b.

It enforces consistency and generalizability of interactive elements.

c.

It regulates communication between the application and the presentation.

d.

It defines the look and feel of the toolkit used for development.

Discuss
Answer: (c).It regulates communication between the application and the presentation. Explanation:The dialog control component in a User Interface Management System (UIMS) is responsible for managing the communication and interaction between the application and the presentation layers. It ensures that the user interface remains consistent with the application's semantics and controls the flow of information between the two.
Q82.
What is a limitation of using formal context-free grammar notations, such as BNF, to describe interactive system dialogs?

a.

They cannot handle command-based interfaces effectively.

b.

They are not suitable for graphically-based interactions.

c.

They lack directionality information for dialog events.

d.

They are unable to represent state transitions.

Discuss
Answer: (c).They lack directionality information for dialog events. Explanation:Formal context-free grammar notations like BNF are limited in expressing the directionality associated with each event in the dialog. This makes it challenging to model communication of values and semantic feedback between application and presentation.
Q83.
State transition diagrams are used for expressing dialogs graphically. What challenge do they face in linking events with their corresponding presentation or application actions?

a.

They lack the ability to represent state transitions.

b.

They struggle with modeling semantic feedback.

c.

They have difficulty expressing directionality.

d.

They can't handle event-based interactions.

Discuss
Answer: (b).They struggle with modeling semantic feedback. Explanation:State transition diagrams, while useful for graphical representation of dialogs, face challenges in accurately linking events to corresponding actions in the presentation or application. The representation of semantic feedback is also not straightforward.
Q84.
What advantage do event languages have over formal grammar notations for describing interactive system dialogs?

a.

They are better suited for graphically-based interactions.

b.

They can express state transitions more effectively.

c.

They provide clear directionality information for events.

d.

They support advanced semantic feedback mechanisms.

Discuss
Answer: (c).They provide clear directionality information for events. Explanation:Event languages offer the advantage of providing clear directionality information for events in the dialog. Unlike formal grammar notations, they can indicate whether an event is initiated by the user or the application.
Q85.
What is a characteristic of production rules in the context of event languages?

a.

They are activated when input is received and produce graphical output.

b.

They describe state transitions in state transition diagrams.

c.

They represent the formal grammar of command-based interfaces.

d.

They model the flow of the dialog in state machines.

Discuss
Answer: (a).They are activated when input is received and produce graphical output. Explanation:In event languages, production rules are activated when input is received and lead to corresponding output responses. They help control the input-output relationship within localized interactions.
Q86.
Which approach is taken by declarative languages in describing the relationship between application and presentation in interactive systems?

a.

Describing the exact sequence of events between application and presentation.

b.

Modeling the input-output behavior using formal context-free grammar.

c.

Concentrating on the flow of information and shared database of values.

d.

Defining event transitions in state transition diagrams.

Discuss
Answer: (c).Concentrating on the flow of information and shared database of values. Explanation:Declarative languages focus on describing how information flows between application and presentation by emphasizing the shared database of values that both sides can access.
Q87.
How do constraint systems contribute to describing the relationship between application and presentation?

a.

By emphasizing event sequencing and interaction patterns.

b.

By providing a graphical representation of the interaction flow.

c.

By establishing a shared database of values for application and presentation.

d.

By specifying a formal context-free grammar for communication.

Discuss
Answer: (c).By establishing a shared database of values for application and presentation. Explanation:Constraint systems, a subset of declarative languages, help in making explicit connections between independent information in presentation and application. Constraints represent dependencies between values that must be maintained.
Q88.
What is the primary advantage of using graphical specification techniques for dialog specification in interactive systems?

a.

They allow for precise event sequencing between application and presentation.

b.

They provide an efficient way to describe formal grammar notations.

c.

They enable programmers to model dialog flow using state transition diagrams.

d.

They allow non-programmers to build interactions using visual objects.

Discuss
Answer: (d).They allow non-programmers to build interactions using visual objects. Explanation:Graphical specification techniques enable the creation of interaction dialogs directly using visual interaction objects. This approach, often referred to as programming by demonstration, opens up dialog specification to non-programmers.
Q89.
How does the ALV (Abstraction-Link-View) model suggest implementing the communication between abstraction and view components?

a.

Through event-based messaging.

b.

Using formal grammar notations.

c.

By creating menu networks.

d.

Via two-way constraints.

Discuss
Answer: (d).Via two-way constraints. Explanation:The ALV model proposes using two-way constraints to implement the communication between abstraction and view components. This ensures that dependencies between values are maintained independently.
Q90.
Which combination of techniques is employed by the Myers Garnet system in the context of user interface management systems?

a.

State transition diagrams and event languages.

b.

Declarative constraints language and graphical specification technique.

c.

Menu networks and formal context-free grammar.

d.

Presentation control and object-oriented programming.

Discuss
Answer: (b).Declarative constraints language and graphical specification technique. Explanation:The Myers Garnet system combines a declarative constraints language with a graphical specification technique for user interface management.
