Q71.
What does the PAC model stand for in the context of interactive system architecture?

a.

Programmable Application Control

b.

Presentation–Abstraction–Component

c.

Process-Application-Control

d.

Presentation–Abstraction–Control

Discuss
Answer: (d).Presentation–Abstraction–Control Explanation:The PAC model stands for Presentation–Abstraction–Control, which is a multi-agent architecture for interactive systems.
Q72.
What is the role of the "abstraction component" in the PAC model?

a.

Managing input and output

b.

Representing application semantics

c.

Ensuring consistency between application and presentation

d.

Managing the control flow of the application

Discuss
Answer: (b).Representing application semantics Explanation:In the PAC model, the "abstraction component" represents the application semantics, which defines the core functionality of the application.
Q73.
How does the PAC model differ from the MVC model in terms of input and output?

a.

PAC combines input and output together, while MVC separates them.

b.

PAC groups input and output separately, while MVC combines them.

c.

PAC has a separate component for input and output, while MVC combines them.

d.

PAC and MVC treat input and output as equivalent components.

Discuss
Answer: (a).PAC combines input and output together, while MVC separates them. Explanation:In the PAC model, input and output are combined in the presentation component, whereas in the MVC model, they are separated between view and controller components.
Q74.
What is the primary purpose of menu networks in interactive systems?

a.

To manage the flow of control within the application

b.

To separate application and presentation components

c.

To implement the dialog controller

d.

To create a network of graphical objects for the user to interact with

Discuss
Answer: (c).To implement the dialog controller Explanation:Menu networks are used to model the communication between application and presentation and to control the dialog in interactive systems.
Q75.
How does the use of callback procedures differ between the X toolkit and the MVC architecture?

a.

In the X toolkit, callbacks are used for communication between view and model, while in MVC, they are used for communication between presentation and application.

b.

In the X toolkit, callbacks are directional from the application to the presentation, while in MVC, they are directional from the presentation to the application.

c.

In the X toolkit, callbacks are used for communication between presentation and application, while in MVC, they are used for communication between view and controller.

d.

In the X toolkit, callbacks are used to control the dialog, while in MVC, they are used to create the user interface.

Discuss
Answer: (b).In the X toolkit, callbacks are directional from the application to the presentation, while in MVC, they are directional from the presentation to the application. Explanation:In the X toolkit, the application registers callbacks with the presentation (view), while in MVC, the presentation (view or controller) registers callbacks with the application (model).
Q76.
What is the primary advantage of using menu networks as an implementation technique for dialog control?

a.

They provide a graphical representation of application semantics.

b.

They simplify the separation of application and presentation components.

c.

They allow for easy integration of multiple applications.

d.

They provide a straightforward way to manage the flow of user interactions.

Discuss
Answer: (d).They provide a straightforward way to manage the flow of user interactions. Explanation:Menu networks model the dialog as a network of menus and submenus, allowing for easy management of user interactions and the flow of control.
Q77.
What is the main advantage of using a multi-agent architecture, such as the PAC model, for interactive systems?

a.

It provides a well-defined separation between application semantics and presentation.

b.

It enforces a strict hierarchy of classes for interaction objects.

c.

It supports single inheritance for building complex interactive systems.

d.

It focuses on direct manipulation interfaces rather than object-oriented programming.

Discuss
Answer: (a).It provides a well-defined separation between application semantics and presentation. Explanation:The PAC (Presentation-Abstraction-Control) model emphasizes separating the application semantics, presentation, and dialog control components. This separation allows for greater portability, reusability, and customization of the user interface, leading to improved system design.
Q78.
In the context of interactive systems, what does the term "PAC" stand for in the PAC model?

a.

Presentation–Application–Control

b.

Panel–Abstraction–Communication

c.

Program–Application–Component

d.

Platform–Architecture–Context

Discuss
Answer: (a).Presentation–Application–Control Explanation:The PAC model stands for Presentation–Abstraction–Control. It refers to a conceptual architecture for interactive systems that separates the presentation of the user interface, the abstraction of application semantics, and the control of the dialog between the two.
Q79.
Which programming paradigm involves an internal control loop within the application program to handle events and interactions?

a.

Callback-based programming

b.

Object-oriented programming

c.

Read–evaluation loop programming

d.

Multi-agent programming

Discuss
Answer: (c).Read–evaluation loop programming Explanation:Read–evaluation loop programming is a paradigm where the application program itself manages the control of the dialog by repeatedly reading events, evaluating their types, and taking appropriate actions based on those types. This approach contrasts with callback-based programming where external entities (such as a notifier) manage the control of events.
Q80.
What is a key benefit of using toolkits in interactive system development?

a.

Toolkits eliminate the need for callback procedures.

b.

Toolkits provide a conceptual architecture for interactive systems.

c.

Toolkits allow for direct manipulation of application semantics.

d.

Toolkits provide ready-made interaction objects with predefined behavior.

Discuss
Answer: (d).Toolkits provide ready-made interaction objects with predefined behavior. Explanation:Toolkits offer a set of pre-built interaction objects, also known as widgets or gadgets, that have predefined behavior. These interaction objects can be used to create consistent and user-friendly user interfaces without needing to program every aspect from scratch.
