Q461.
What is sequential cohesion?

a.

The elements are grouped into modules in a haphazard way

b.

The elements realize tasks that are logically related

c.

The module consists of a sequence of elements where the output of one element serves as input to the next element

d.

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

Discuss
Answer: (c).The module consists of a sequence of elements where the output of one element serves as input to the next element Explanation:Sequential cohesion occurs when a module consists of a sequence of elements where the output of one element serves as input to the next element.
Q462.
What is functional 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.

All elements in a module with functional cohesion contribute to the one single function of the module.

Discuss
Answer: (d).All elements in a module with functional cohesion contribute to the one single function of the module. Explanation:Functional cohesion is a type of cohesion in software design where all elements of a module contribute to a single, well-defined function of that module. In other words, all elements of the module work together to achieve a common goal. The function is often one of transforming a single input data into a single output data. Examples of functional cohesion can include mathematical subroutines or modules such as "execute the next edit command" or "translate the program given." This type of cohesion is considered to be one of the strongest levels of cohesion.
Q463.
What are the heuristics suggested by Stevens et al. in the classic paper on structured design to determine the degree of cohesion of a module?

a.

Write down a sentence that describes the function of the module and examine that sentence

b.

Analyze the properties of the module to look for sequential or communicational cohesion

c.

Identify the strongest possible cohesion between the elements of the module

d.

Both a and b

Discuss
Answer: (d).Both a and b Explanation:The heuristics suggested by Stevens et al. in the classic paper on structured design to determine the degree of cohesion of a module is to write down a sentence that describes the function of the module and examine that sentence and analyze the properties of the module to look for sequential or communicational cohesion.
Q464.
What type of cohesion does a module exhibit if the sentence that describes its function is compound and contains more than one verb?

a.

Sequential cohesion

b.

Communicational cohesion

c.

Either a or b

d.

Functional cohesion

Discuss
Answer: (c).Either a or b Explanation:If the sentence that describes the function of a module is compound and contains more than one verb, then the module is likely to exhibit sequential or communicational cohesion.
Q465.
What type of cohesion does a module exhibit if the sentence that describes its function contains words that relate to time?

a.

Sequential cohesion

b.

Communicational cohesion

c.

Temporal cohesion

d.

Either a or c

Discuss
Answer: (d).Either a or c Explanation:If the sentence that describes the function of a module contains words that relate to time, then the module is likely to exhibit sequential or temporal cohesion.
Q466.
What type of cohesion does a module exhibit if the sentence that describes its function contains words like "initialize"?

a.

Sequential cohesion

b.

Communicational cohesion

c.

Temporal cohesion

d.

Functional cohesion

Discuss
Answer: (c).Temporal cohesion Explanation:If the sentence that describes the function of a module contains words like "initialize", then the module is likely to exhibit temporal cohesion.
Q467.
What is the difference between functional cohesion and data cohesion?

a.

Data cohesion is stronger than functional cohesion

b.

Data cohesion is weaker than functional cohesion

c.

They are equally strong

d.

None of the above

Discuss
Answer: (a).Data cohesion is stronger than functional cohesion Explanation:Data cohesion is even stronger than functional cohesion.
Q468.
What does a high degree of coupling indicate?

a.

Weak dependence between modules

b.

Relatively independent modules

c.

Strong dependence between modules

d.

None of the above

Discuss
Answer: (c).Strong dependence between modules Explanation:A high degree of coupling between modules means that they have a strong dependence, making it difficult to comprehend and adapt the modules.
Q469.
What is the desired feature of a software design?

a.

High degree of coupling

b.

Loose coupling

c.

Strong coupling

d.

Tight coupling

Discuss
Answer: (b).Loose coupling Explanation:Loose coupling is a desirable feature of a software design as it makes the modules relatively independent and easier to comprehend and adapt.
Q470.
What is content coupling?

a.

Modules communicate through an external medium

b.

One module directly affects the working of another module

c.

Two modules have shared data

d.

One module directs the execution of another module

Discuss
Answer: (b).One module directly affects the working of another module Explanation:Content coupling occurs when one module directly affects the working of another module by changing its data or control is passed from one module to the middle of another.
