Q451.
What are the benefits of using data abstraction in software development?

a.

Better decision-making about data structures and their representation.

b.

Improved information hiding.

c.

Easier movement from design to code.

d.

All of the above.

Discuss
Answer: (b).Improved information hiding. Explanation:One of the benefits of using data abstraction in software development is improved information hiding, as it allows for a separation between the implementation and specification of data types.
Q452.
How did the notion of data abstraction evolve in the field of programming languages?

a.

With the introduction of procedures to avoid repetition of instruction sequences.

b.

With the development of formal data type specifications and language notions for modules.

c.

With the concept of control abstraction.

d.

None of the above.

Discuss
Answer: (b).With the development of formal data type specifications and language notions for modules. Explanation:The notion of data abstraction evolved in the field of programming languages with the development of formal data type specifications and language notions for modules, such as the class concept of SIMULA-67.
Q453.
What is the difference between data abstraction and control abstraction?

a.

Data abstraction abstracts from the implementation and specification of data types, while control abstraction abstracts from the precise order in which a sequence of events is to be handled.

b.

Data abstraction is used in software development, while control abstraction is not.

c.

Data abstraction is easier to implement, while control abstraction is more complicated.

d.

Data abstraction is a prime example of information hiding, while control abstraction is not.

Discuss
Answer: (a).Data abstraction abstracts from the implementation and specification of data types, while control abstraction abstracts from the precise order in which a sequence of events is to be handled. Explanation:Data abstraction abstracts from the implementation and specification of data types, while control abstraction abstracts from the precise order in which a sequence of events is to be handled. They are two different types of abstraction techniques used in software development.
Q454.
What is cohesion in modular design?

a.

A measure of the mutual affinity of the elements of a module.

b.

A measure of the mutual independence of the elements of a module.

c.

A measure of the mutual dependence of the elements of a module.

d.

A measure of the mutual relationship of the elements of a module.

Discuss
Answer: (a).A measure of the mutual affinity of the elements of a module. Explanation:Cohesion refers to the strength of the relationship between the elements within a module and the design aim is to make it as strong as possible.
Q455.
What is coupling in software design?

a.

A measure of the mutual affinity of the elements of a module

b.

The glue that keeps the modules together

c.

The typology for the individual modules

d.

The type of connections between the modules

Discuss
Answer: (d).The type of connections between the modules Explanation:In software design, coupling is the type of connections between the modules and indicates the relationships between those modules.
Q456.
What is coincidental cohesion?

a.

Elements are grouped into modules in a haphazard way

b.

The elements realize tasks that are logically related

c.

The various elements of a module are independent but they are activated at about the same point in time

d.

The elements of a module operate on the same (external) data

Discuss
Answer: (a).Elements are grouped into modules in a haphazard way Explanation:Coincidental cohesion is a type of cohesion where elements are grouped into modules in a haphazard way, with no significant relation between the elements.
Q457.
What is an example of logical cohesion?

a.

A module that contains all input routines

b.

An initialization module

c.

A module that consists of a number of elements that have to be executed in some given order

d.

A module that transforms a single input datum into a single output datum

Discuss
Answer: (a).A module that contains all input routines Explanation:Logical cohesion occurs when the elements of a module realize tasks that are logically related, like a module that contains all input routines.
Q458.
What is temporal cohesion?

a.

The elements are grouped into modules in a haphazard way

b.

The elements realize tasks that are logically related

c.

The various elements of a module are independent but they are activated at about the same point in time

d.

The elements of a module operate on the same (external) data

Discuss
Answer: (c).The various elements of a module are independent but they are activated at about the same point in time Explanation:Temporal cohesion occurs when the various elements of a module are independent but they are activated at about the same point in time, like an initialization module.
Q459.
What is procedural cohesion?

a.

The elements are grouped into modules in a haphazard way

b.

The elements realize tasks that are logically related

c.

The various elements of a module are independent but they are activated at about the same point in time

d.

A module that consists of a number of elements that have to be executed in some given order

Discuss
Answer: (d).A module that consists of a number of elements that have to be executed in some given order Explanation:Procedural cohesion occurs when a module consists of a number of elements that have to be executed in some given order, like a module that first reads some datum, then searches a table, and finally prints a result.
Q460.
What is communicational cohesion?

a.

The elements are grouped into modules in a haphazard way

b.

The elements realize tasks that are logically related

c.

The various elements of a module are independent but they are activated at about the same point in time

d.

The elements of a module operate on the same (external) data

Discuss
Answer: (d).The elements of a module operate on the same (external) data Explanation:Communicational cohesion occurs when the elements of a module operate on the same (external) data, like a module that reads some data from a disk, performs certain computations on those data, and prints the result.
