Why do apps send notifications?
Show answer & explanation
Answer: Alert users to important updates
Alert users to important updates ✓ — Correct! Notifications inform users of time-sensitive information without opening the app: messages, reminders, breaking news, deliveries, etc. They use push notification services (Apple Push Notification, Firebase Cloud Messaging) that maintain persistent connections. Apps register with these services, which send notifications even when apps aren't running. Users can control which apps send notifications in settings!
Track user location — Wrong. Notifications don't track location (though some apps may request location separately). They deliver timely information to keep users informed.
Consume device memory — Wrong. Notifications use negligible memory. They're designed to quickly alert users about important information without keeping apps constantly open.
