Q441.
What is the result of stepwise decomposition in procedural abstraction?

a.

A hierarchical structure

b.

A non-hierarchical structure

c.

A flat structure

d.

None of the above.

Discuss
Answer: (a).A hierarchical structure Explanation:The result of stepwise decomposition in procedural abstraction is a hierarchical structure. The top node of the structure denotes the problem to be solved and the leaves denote primitive problems.
Q442.
What is procedural abstraction in software development?

a.

A method of solving software problems by decomposing the problem into subproblems

b.

A technique to find a hierarchy in the program's control structure

c.

A way to represent the sequence of actions through the name of a procedure

d.

A method of finding a hierarchy in the program's data

Discuss
Answer: (c).A way to represent the sequence of actions through the name of a procedure Explanation:Procedural abstraction is the application of the procedure concept that uses the name of a procedure (or method) to denote the corresponding sequence of actions.
Q443.
What is the purpose of procedural abstraction in software development?

a.

To make the programs adaptable and easily comprehensible

b.

To tackle software problems in a way that closely matches the human problem-solving process

c.

To find a hierarchy in the program's data

d.

To make the program output-focused

Discuss
Answer: (b).To tackle software problems in a way that closely matches the human problem-solving process Explanation:Procedural abstraction is aimed at finding a hierarchy in the program’s control structure and offers an important means of tackling software problems in a way that closely matches the human problem-solving process.
Q444.
How does procedural abstraction differ from data abstraction in software development?

a.

Procedural abstraction is focused on finding a hierarchy in the program's control structure, while data abstraction is focused on finding a hierarchy in the program's data

b.

Procedural abstraction is aimed at making the program output-focused, while data abstraction makes the program adaptable and easily comprehensible

c.

Both are the same concepts in software development

d.

Procedural abstraction is used to solve software problems while data abstraction is used to represent the sequence of actions

Discuss
Answer: (a).Procedural abstraction is focused on finding a hierarchy in the program's control structure, while data abstraction is focused on finding a hierarchy in the program's data Explanation:Procedural abstraction is focused on finding a hierarchy in the program's control structure, while data abstraction is aimed at finding a hierarchy in the program's data.
Q445.
What is the result of using the input-process-output approach in software development?

a.

Programs that are easily adaptable and comprehensible

b.

Programs that follow a strong time orientation

c.

Programs that are difficult to adapt and comprehend

d.

Programs with a hierarchical data structure

Discuss
Answer: (c).Programs that are difficult to adapt and comprehend Explanation:The input-process-output approach results in programs that may be difficult to adapt and comprehend, as it has a strong time orientation and decomposes the problem into subproblems that follow each other in time.
Q446.
What type of data structures are found at a low level in the hierarchy of data structures in software development?

a.

Application-oriented objects such as 'paragraph' or 'book'

b.

Primitive data structures for integers, real numbers, truth values, characters, etc.

c.

More complicated data structures such as stacks and binary trees

d.

Data structures with a hierarchical control structure

Discuss
Answer: (c).More complicated data structures such as stacks and binary trees Explanation:Using primitive data structures such as integers, real numbers, truth values, characters, etc., we can construct more complicated data structures like stacks and binary trees. These structures occur at a fairly low level in the hierarchy of data structures and are of general use in application software.
Q447.
What is data abstraction?

a.

The process of using the name of a procedure to denote the corresponding sequence of actions

b.

The way in which humans solve problems

c.

The abstraction of details that are not relevant at a certain level

d.

The finding of a hierarchy in the program’s data

Discuss
Answer: (c).The abstraction of details that are not relevant at a certain level Explanation:Data abstraction is the abstraction of details that are not relevant at a certain level, specifically with regard to the program’s data.
Q448.
What is object-oriented design?

a.

The process of using the name of a procedure to denote the corresponding sequence of actions

b.

The way in which humans solve problems

c.

The finding of a hierarchy in the program’s control structure

d.

The encapsulation of the type of object and the associated operations in one module

Discuss
Answer: (d).The encapsulation of the type of object and the associated operations in one module Explanation:Object-oriented design is the application of data abstraction during design, where the type of object and the associated operations are encapsulated in one module.
Q449.
What is data abstraction in software development?

a.

A way to maintain a syntactic separation between the implementation and specification of data types.

b.

A method to solve software problems with data structures.

c.

A prime example of information hiding.

d.

A way to abstract from the precise order in which a sequence of events is to be handled.

Discuss
Answer: (a).A way to maintain a syntactic separation between the implementation and specification of data types. Explanation:In software development, data abstraction is a way to maintain a syntactic separation between the implementation and specification of data types, such as by using constructs like packages, classes, and structs in languages like Ada, Java, and C++.
Q450.
What is the purpose of data abstraction?

a.

To make the implementation-independent interfaces public.

b.

To impose the result on all other components.

c.

To avoid repetition of instruction sequences.

d.

To explicitly model control abstraction.

Discuss
Answer: (a).To make the implementation-independent interfaces public. Explanation:The purpose of data abstraction is to create a separate subproblem and make only the procedural, implementation-independent interfaces public, rather than making decisions about data structures and their representation at an early stage and imposing the result on all other components.
