Few questions about different sound types

Hello, i’m beginning to learn sound and audio in UE. i’d like to know the following; because even if i followed some courses they didn’t clearly tell you it

  • what are the main sound types. i read there were sounds, cues, sound effects, and music files. is that correct, is there anything else i should know. what are the differences between these things

  • what are the naming conventions of these files

Thank you
