Relation between NAS and FreeRADIUS

Hi It is possible that my question is low level but it is key for me. I want to ask that NAS provide internet or FreeRADIUS. I mean i should connect internet connection to NAS or FreeRADIUS. Does NAS just use FreeRADIUS or any Radius Server to authenticate user and register accounting data in Radius.
