Which term describes the practice of creating concise representations to help understanding of complex phenomena?

• A. Abstraction
• B. Iterative innovation
• C. URL
• D. IP address

Answer: (A)

Abstraction is the practice of creating concise representations that focus on the important aspects of something while leaving out the details. By simplifying complex phenomena into models or general concepts, you can understand, compare, and reason about how systems work without getting bogged down in every detail. In programming and computer science, abstraction lets you think at a high level—using ideas like functions, classes, or data models—without needing to manage every low-level operation all at once. For example, a map app presents you with routes and distances, not every calculation the app performs behind the scenes. The other terms don’t fit this idea: iterative innovation relates to refining ideas through cycles rather than creating concise representations; a URL is a web address; an IP address identifies a device on a network. Abstraction best captures the notion of making something complex easier to grasp through simplified models.
