The word is clearly made up of 'Internet' (internet) and 'Nutzer' (user). A 'Nutzer' is a person who 'nutzt' (uses) something. So an internet user is literally a person who uses the internet.

Every internet user should pay attention to the security of their data.
The base word 'Nutzer' (user) is derived from the verb 'nutzen' (to use). This structure, verb + the ending '-er' for a person, is very common in German, for example 'fahren' (to drive) → 'Fahrer' (driver) or 'lesen' (to read) → 'Leser' (reader).

'der Nutzer' and 'der Internetnutzer' are very close when it comes to digital services. 'Nutzer' is more general: you can be the user of an app, a computer, a bicycle, or a service. 'Internetnutzer' is more specific and refers only to people who use the internet. Learners may confuse the words because an internet user is often also a user of a website or app. If the context is already clearly digital, 'Nutzer' is often enough. If the internet as a whole is meant explicitly, 'Internetnutzer' is more precise.
