 A _service_ is a component without a user interface, and is used to perform long-running operations in the background.
 There are three kinds of services:
 
-- _foreground_ services: they are strictly related to user's interaction (for example music playback), so it's harder for the system to kill them.
-- _background_ services: they are not directly related to user's activities, so they can be killed if more RAM is needed.
-- _bound_ services: they are  offers a client-server interface that allows components to interact with the service, send requests, receive results, and even do so across processes with interprocess communication (IPC).
