Q21.

What is object-oriented design (OOD)?

The process of designing a regular procedure-based program

The process of dividing a program into objects

The process of defining a set of procedures that are associated with an object

The process of treating objects as completely isolated entities that can only be accessed through their well-defined interfaces

Discuss

Answer: (b).The process of dividing a program into objects Explanation:Object-oriented design (OOD) is the process of dividing a program into objects.

Q22.

What is an object in OOD?

A program component that has both data and code associated with it

A piece of code with a well-defined purpose that can be invoked by other areas in the program

A set of publicly accessible procedures that are associated with an object

A program component that is not interested in any of its implementation details

Discuss

Answer: (a).A program component that has both data and code associated with it Explanation:An object in OOD is a program component that has both data and code associated with it.

Q23.

What are clients in the context of OOD?

Other components in the program that require the services of an object but are not interested in any of its implementation details

A set of procedures that are associated with an object

Publicly accessible procedures that are invoked primarily by clients of an object

Data that is part of an object and is usually private, meaning that it can only be accessed by object code, but not from the outside world

Discuss

Answer: (a).Other components in the program that require the services of an object but are not interested in any of its implementation details Explanation:Clients in the context of OOD are other components in the program that require the services of an object but are not interested in any of its implementation details.

Q24.

What is the most commonly used form of encapsulation in any programming language?

Interfaces

Data structures

Procedures

Objects

Discuss

Answer: (c).Procedures Explanation:Procedures are the most commonly used form of encapsulation in any programming language.

Q25.

What is an object in OOD methodology?

A program component that has data and code associated with it

A program component that has only data associated with it

A program component that has only code associated with it

A program component that has no data or code associated with it

Discuss

Answer: (a).A program component that has data and code associated with it Explanation:An object is a program component that has both data and code associated with it in OOD methodology.

Q26.

What are clients in OOD methodology?

Objects that require the services of other objects but are not interested in any of their implementation details

Objects that provide services to other objects

Procedures that are associated with objects

Data that is part of an object and is usually private

Discuss

Answer: (a).Objects that require the services of other objects but are not interested in any of their implementation details Explanation:Clients are other components in the program that require the services of an object but are not interested in any of its implementation details.

Q27.

What is inheritance in OOD?

A feature that allows designers to establish a generic object type and implement many specific implementations of that type that offer somewhat different functionality

A feature that allows developers to treat objects as completely isolated entities that can only be accessed through their well-defined interfaces

A feature that allows upgrading individual components in a program without updating the entire program

A feature that allows for adding functionality to a program by embedding static libraries into it

Discuss

Answer: (a).A feature that allows designers to establish a generic object type and implement many specific implementations of that type that offer somewhat different functionality Explanation:Inheritance is a feature that allows designers to establish a generic object type and implement many specific implementations of that type that offer somewhat different functionality.

Q28.

What is the idea behind inheritance in OOD?

To establish a generic object type and implement many specific implementations of that type that offer somewhat different functionality

To treat objects as completely isolated entities that can only be accessed through their well-defined interfaces

To allow upgrading individual components in a program without updating the entire program

To add functionality to a program by embedding static libraries into it

Discuss

Answer: (a).To establish a generic object type and implement many specific implementations of that type that offer somewhat different functionality Explanation:The idea behind inheritance is to establish a generic object type and implement many specific implementations of that type that offer somewhat different functionality.

Q29.

What is polymorphism in OOD?

The concept of having multiple descendant objects that can implement entirely different functionalities but export the same interface

The concept of declaring a base object that includes a declaration of a generic interface to be used by every object that inherits from that base object

The concept of a set of procedures that is related to an object and can manipulate its data

The concept of treating objects as completely isolated entities that can only be accessed through their well-defined interfaces.

Discuss

Answer: (a).The concept of having multiple descendant objects that can implement entirely different functionalities but export the same interface Explanation:Polymorphism refers to the concept of having multiple descendant objects that can implement entirely different functionalities but export the same interface. This means that clients can use these objects without knowing the specific object type they are dealing with, they are only aware of the base object's type.

Q30.

What are the two perspectives required to understand how data is managed in a program?

High-level perspective and hardware perspective

High-level perspective and low-level perspective

System-level perspective and machine-level perspective

Programmer's perspective and developer's perspective

Discuss

Answer: (b).High-level perspective and low-level perspective Explanation:To understand how data is managed in a program, one must have both the high-level perspective (as viewed by software developers) and the low-level perspective (as viewed by reversers). High-level languages tend to simplify data management and hide the details of how data is managed at the system level, whereas low-level languages provide a more detailed view of data management at the machine level.
