Q1.
What is program structure?

a.

Breaking down a program into small chunks for human manageability

b.

Compiling and linking a program for machine efficiency

c.

Running sequentially with occasional goto commands

d.

Eliminating redundant structural details in a program

Discuss
Answer: (a).Breaking down a program into small chunks for human manageability Explanation:Program structure is the process of breaking down a program into small, manageable chunks or "units" for human comprehension and organization. This allows individuals to divide the work among themselves and create a mental map of the program.
Q2.
Why do humans need program structure?

a.

To eliminate redundant structural details

b.

To make the program run more efficiently

c.

To make it easier to understand and manage the program

d.

None of the above

Discuss
Answer: (c).To make it easier to understand and manage the program Explanation:Humans need program structure to make it easier to understand and manage a program, as large and complex programs can be difficult to comprehend and work with without breaking them down into smaller, more manageable units.
Q3.
What is the problem with program structure from a machine's perspective?

a.

Machines don't need program structure as much as humans do

b.

Program structure makes the program run less efficiently

c.

Program structure makes it harder for machines to understand the program

d.

None of the above

Discuss
Answer: (a).Machines don't need program structure as much as humans do Explanation:From a machine's perspective, program structure is not as important as it is for humans, as machines can efficiently run code without the need for program structure. In fact, machines often eliminate some structural elements during the process of compiling and linking a program.
Q4.
What is the role of program structure in reverse engineering?

a.

To make the program run more efficiently

b.

To eliminate redundant structural details in a program

c.

To reconstruct the map of various components that make up a program

d.

None of the above

Discuss
Answer: (c).To reconstruct the map of various components that make up a program Explanation:In reverse engineering, the goal is to reconstruct the map of various components that make up a program, and program structure plays a crucial role in this process. Reversers must try to break down a program into its smaller units to create a mental image of the program in their minds.
Q5.
How do software developers break down software into manageable chunks?

a.

By viewing the program as a set of separate black boxes responsible for specific tasks

b.

By integrating all components of the system into one large box

c.

By breaking down the program into individual lines of code

d.

By viewing the program as a single, cohesive unit

Discuss
Answer: (a).By viewing the program as a set of separate black boxes responsible for specific tasks Explanation:Software developers break down software into manageable chunks by viewing the program as a set of separate black boxes responsible for specific tasks.
Q6.
What is the purpose of encapsulation in software development?

a.

To hide unnecessary details about the internal implementation of a component

b.

To expose all details about the internal implementation of a component

c.

To make a component available only to certain users

d.

To make a component harder to access for security purposes

Discuss
Answer: (a).To hide unnecessary details about the internal implementation of a component Explanation:Encapsulation is the process of each component box encapsulating certain functionality and simply making it available to whoever needs it, without exposing unnecessary details about the internal implementation of the component.
Q7.
Can component boxes be developed by different people or groups?

a.

Yes

b.

No

c.

Only in certain programming languages

d.

Only for small projects

Discuss
Answer: (a).Yes Explanation:Component boxes are frequently developed by different people or even by different groups.
Q8.
What is the primary factor in developing a robust and reliable software product?

a.

Well-implemented and reliable component boxes

b.

A large number of component boxes

c.

Complex component box interactions

d.

The use of the most popular programming languages

Discuss
Answer: (a).Well-implemented and reliable component boxes Explanation:Developing a robust and reliable product rests primarily on two factors: that each component box is well implemented and reliably performs its duties, and that each box has a well defined interface for communicating with the outside world.
Q9.
What is the first step in most reversing scenarios?

a.

Determining the component structure of the application

b.

Picking a component of interest and delving into its details

c.

Introducing new components to the system

d.

Removing unnecessary components from the system

Discuss
Answer: (a).Determining the component structure of the application Explanation:In most reversing scenarios, the first step is to determine the component structure of the application and the exact responsibilities of each component.
Q10.
What is the general idea behind breaking down software into separate black boxes?

a.

To make the program easier to view

b.

To make the program more complex

c.

To make the program more difficult to manage

d.

To view the program as a set of separate tasks

Discuss
Answer: (d).To view the program as a set of separate tasks Explanation:The general idea behind breaking down software into separate black boxes is to view the program as a set of separate tasks that are responsible for specific functionality.
