What does "remote data" mean in mobile development?

Remote data is information stored on a server or cloud, outside the user's device, which apps access through the internet.

Why can't all data be stored locally on a mobile device?

Local storage is limited and data can change often, so apps fetch updated data from remote servers to stay current.

beginner

How does a network call help keep app data fresh?

A network call asks the server for the latest data, so the app shows up-to-date information to the user.

Give an example of when a mobile app uses a network call.

When you open a weather app, it makes a network call to get the current weather from a remote server.

Why do mobile apps fetch data from remote servers?

Explain why mobile apps need to make network calls to fetch remote data.

Think about how apps get fresh data and why they can't keep everything on the phone.

Describe a real-life example where a network call is essential for a mobile app.

Consider apps you use daily that show changing information.
