UIThread -> This is the singular main thread which runs when Android first launches and triggers Application.onStart().

Services are processes which run on the main thread by default, but they can be pushed to the background. If intensive services run on the main thread, they can be Blocking (usually networking operations and such). So, in that case, it is much better to put networking operations on the background thread and use that instead of using the main or the UIThread.
