Mobile App Design Technology & Digital Applications 5

Question 1

Which app architecture approach packages all features into a single deployable unit with shared code and resources?

Accepted Answer

Monolithic architecture

Answer

A monolithic architecture bundles all app functionality into one codebase and deployment unit, which is simpler initially but harder to scale modularly.

Question 2

What is the role of a 'service worker' in a Progressive Web App?

Accepted Answer

Acting as a proxy to intercept network requests and enable offline functionality

Answer

A service worker is a background script that intercepts fetch requests, enabling caching strategies and offline support independently of the main app thread.

Question 3

In mobile app analytics, what does a 'funnel' visualization show?

Accepted Answer

Drop-off rates at each step of a multi-step user journey

Answer

A funnel tracks how many users complete each step of a defined sequence, revealing where users abandon the flow most frequently.

Question 4

What distinguishes cold start from warm start in mobile app launch performance?

Accepted Answer

Cold start = process not in memory, full initialization required; warm start = process already in memory

Answer

A cold start requires the OS to create a new process and initialize everything from scratch, while a warm start resumes an already-initialized process from memory.

Question 5

Which data serialization format is most commonly used for mobile app API communication due to its lightweight nature?

Accepted Answer

JSON

Answer

JSON is the dominant format for mobile API communication because it is lightweight, human-readable, and natively supported by JavaScript and most mobile SDKs.
