NPTEL Software Design Quiz AC

Which design approach is more suitable for complex systems where the overall architecture is not well-defined initially?

• Top-down design

• Bottom-up design

• Both approaches are equally suitable

• Neither approach is suitable for complex systems

What is the primary advantage of bottom-up design?

• It provides a clear and comprehensive overview of the entire system

• It is faster and more efficient in terms of development

• It allows for early testing and integration of smaller components

• It is more suitable for small, simple systems

Which design approach is often associated with a "divide and conquer" strategy?

• Top-down design

• Bottom-up design

• Both top-down and bottom-up design

• Neither approach uses a "divide and conquer" strategy

In bottom-up design, what is typically the starting point for design efforts?

• The user interface

• High-level modules and subsystems

• Detailed algorithms and coding

• System testing

Which design approach is often used in agile development methodologies?

• Top-down design

• Bottom-up design

• A combination of both approaches

• Neither approach is associated with agile methodologies

In top-down design, what is the term for gradually adding more detail to the design as you move from high-level modules to lower-level modules?

• Decomposition

• Integration

• Incremental design

• Abstraction

What is coupling in software design?

• A measure of how closely related two modules are in terms of their functionality

• The process of breaking down a program into smaller functions

• The way modules communicate with each other

• The level of abstraction used in a module

High coupling in software design is generally considered:

• A desirable characteristic that enhances code reusability

• A sign of good modular design

• A design principle that reduces the likelihood of bugs

• Undesirable and can lead to maintenance challenges

Which type of coupling is generally considered the most desirable in software design?

• Tight coupling

• Loose coupling

• Content coupling

• Common coupling

What is "content coupling" in software design?

• It refers to modules that share a global variable

• It describes modules that communicate through a well-defined interface

• It represents modules that are closely related in terms of their functionality

• It is a measure of the similarity of data structures in different modules
