Q481.
What is one of the reasons for simple interfaces being important?

a.

It makes decisions harder to make.

b.

It makes it harder to re-use modules.

c.

It makes the system less error-prone.

d.

It reduces memory capacity for information processing.

Discuss
Answer: (c).It makes the system less error-prone. Explanation:Empirical studies show that interfaces exhibiting weak coupling and strong cohesion are less error-prone than those that do not have these properties.
Q482.
What is the principle of information hiding according to David Parnas?

a.

Each module has a secret which it hides to other modules

b.

All modules have access to the same information

c.

Modules have minimal cohesion and coupling

d.

Modules have low error-proneness

Discuss
Answer: (a).Each module has a secret which it hides to other modules Explanation:The principle of information hiding originates from David Parnas's seminal paper and states that each module has a secret which it hides to other modules.
Q483.
How is information hiding related to cohesion and coupling in design?

a.

It increases coupling between modules

b.

It decreases cohesion within modules

c.

It decreases coupling between modules and increases cohesion within modules

d.

It increases coupling between modules and decreases cohesion within modules

Discuss
Answer: (c).It decreases coupling between modules and increases cohesion within modules Explanation:Information hiding decreases coupling between modules and increases cohesion within modules. It increases cohesion as the module's secret binds the module's constituents together and decreases coupling as the module's secret does not permeate the module's boundary.
Q484.
How does information hiding affect the maintainability of software according to Boehm (1983)?

a.

It has a positive impact

b.

It has no impact

c.

It has a negative impact

d.

It depends on the programming language used

Discuss
Answer: (a).It has a positive impact Explanation:According to Boehm (1983), information hiding has a positive impact on the maintainability of software. It helps to confirm the impact of such techniques on the maintainability of software.
Q485.
What is the relationship between information hiding, abstraction, cohesion, and coupling?

a.

Information hiding decreases abstraction and cohesion

b.

Information hiding increases abstraction and decreases cohesion

c.

Information hiding increases abstraction and cohesion

d.

Information hiding decreases abstraction and increases cohesion

Discuss
Answer: (c).Information hiding increases abstraction and cohesion Explanation:If a module hides some design decision, the user of that module may abstract from (ignore) the outcome of that decision. Information hiding increases cohesion, since the module's secret is what binds the module's constituents together.
Q486.
Does the separation of concerns obtained during the design stage depend on the programming language used?

a.

Yes, it depends on the programming language used

b.

No, it does not depend on the programming language used

c.

Can't say

d.

None of the above

Discuss
Answer: (a).Yes, it depends on the programming language used Explanation:It depends on the programming language used whether the separation of concerns obtained during the design stage will be identifiable in the ultimate code.
Q487.
What is the complexity of a problem in a general sense?

a.

The amount of resources required to change it

b.

The amount of resources required for its solution

c.

The behavior of the problem

d.

The well-established field in which many results have been obtained

Discuss
Answer: (b).The amount of resources required for its solution Explanation:The complexity of a problem in a general sense refers to the amount of resources required for its solution.
Q488.
What is the complexity of software in the Software development context?

a.

The behavior of the software

b.

The amount of resources required to change it

c.

The amount of resources required for its solution

d.

The well-established field in which many results have been obtained

Discuss
Answer: (b).The amount of resources required to change it Explanation:In the Software development context, complexity refers to attributes of the software that affect the effort needed to construct or change a piece of software.
Q489.
What are the internal attributes of software complexity?

a.

The behavior of the software

b.

The amount of resources required to change it

c.

The amount of resources required for its solution

d.

The well-established field in which many results have been obtained

Discuss
Answer: (b).The amount of resources required to change it Explanation:These attributes can be measured purely in terms of the software itself and do not require execution of the software to determine their values.
Q490.
What is the difference between the complexity of a problem and the complexity of the computation performed?

a.

The complexity of a problem refers to behavior while the complexity of the computation performed refers to the amount of resources required for its solution

b.

The complexity of the computation performed refers to time or memory needed while the complexity of a problem refers to the behavior of the problem

c.

The complexity of the computation performed is a well-established field while the complexity of a problem is still a rather elusive notion

d.

The complexity of a problem refers to the amount of resources required for its solution while the complexity of the computation performed refers to time or memory needed

Discuss
Answer: (b).The complexity of the computation performed refers to time or memory needed while the complexity of a problem refers to the behavior of the problem Explanation:The complexity of the computation performed refers to time or memory needed while the complexity of a problem refers to the behavior of the problem.
