How does database connectivity affect app performance?

Good connectivity means fast data access and smooth user experience. Poor connectivity can cause delays or errors in showing data.

beginner

What role do drivers or libraries play in database connectivity?

Drivers or libraries are like translators that help Node.js talk to different databases easily and correctly.

intermediate

What happens if a Node.js app loses database connectivity?

The app may fail to save or load data, causing errors or broken features, which hurts user trust and app reliability.

What does database connectivity enable in a Node.js app?

A Changing the app's color scheme

B Data storage and retrieval

C Running the app offline

D Improving keyboard shortcuts

Database connectivity allows the app to store and retrieve data from a database.

Which of these is a common tool to connect Node.js to a database?

A MongoDB driver

B Express.js

C React

D CSS

MongoDB driver is a library that helps Node.js connect to MongoDB databases.

What can happen if database connectivity is slow?

A App shows delays or errors

B App loads data faster

C App crashes immediately

D App changes its layout

Slow connectivity causes delays or errors in data loading.

Why do Node.js apps need database connectivity?

A To interact with users

B To play sounds

C To store and manage data

D To change fonts

Database connectivity is needed to store and manage data.

What is a risk if a Node.js app loses database connection?

A App becomes faster

B App changes color

C App updates automatically

D App cannot save or load data

Losing database connection means the app cannot save or load data properly.

Explain in simple terms why database connectivity matters for a Node.js application.

Think about what happens if the app cannot talk to its data storage.

Describe what can go wrong if a Node.js app has poor database connectivity.

Consider how delays or failures in data affect the app's behavior.
