What possible states can a software application have during its operation?

An iOS application can be in several states during its operation:

• Not Running: The app is not launched or has been terminated by the system.
• Inactive: The app is on the screen but not receiving events (e.g., during an incoming call or system notification).
• Active: The app is in the foreground and receiving user input.
• Background: The app is running in the background, performing tasks like music playback or data download.
• Suspended: The app is in memory but not executing code. The system may unload it if needed.

Understanding these states is important for proper resource management and data preservation.
