Question 1

What is abstraction?

Answer 1

Simplifying complex problems by representing essential features while hiding unnecessary details.

Abstraction helps in focusing on relevant aspects of a system.

Question 2

Define architecture abstraction.

Answer 2

High-level representation or simplification of complex systems, designs, or structures.

This type of abstraction is crucial in understanding system architecture.

Question 3

What is decomposition in the context of system design?

Answer 3

The idea of breaking down large entities into smaller and more specialized ones.

Model decomposition provides multiple levels of granularity.

Question 4

What does model decomposition provide?

Answer 4

Multiple levels of granularity.

This allows for detailed analysis and understanding of complex systems.

Question 5

Define coupling.

Answer 5

The density of dependencies among classes.

Coupling affects how changes in one class impact others.

Question 6

What does high coupling indicate?

Answer 6

There are many dependencies.

High coupling can lead to increased complexity and difficulty in maintaining code.

Question 7

What does low coupling indicate?

Answer 7

There are few dependencies.

Low coupling is generally desirable for easier maintenance and flexibility.

Question 8

Define cohesion.

Answer 8

The degree of unity or closeness.

High cohesion within a module is preferred for clarity and maintainability.
