## 1. What is a Service in Android?

**Answer**

A Service is an Android component that runs in the background without a user interface. It allows performing long-running operations like downloading files or playing music. It must be declared in the Manifest.

## 2. What is the difference between a Started Service and a Bound Service?

**Answer**

A Started Service is launched with startService() and continues running in the background independently of the component that started it. A Bound Service is connected to one or more components via bindService(), and stops automatically when all clients unbind. A service can be both Started and Bound.

## 3. How to start a Started Service?

**Answer**

Use startService(Intent) or startForegroundService(Intent) for Android 8+. The service receives onStartCommand() and continues running. It must stop itself with stopSelf() or be stopped with stopService().
