What does "full access" mean?
"Full" here just means "complete" or "100%," so "full access" can be understood as meaning "complete access" or "100%" (access without barriers) in this context. Although "access" provides the same general meaning, "full" adds an element of emphasis to the expression and is a bit of a stronger statement. Ex: John is still a minor, so he doesn't get full access to his bank account until he turns 18. Ex: I got the master keys yesterday, so now I have full access to the whole building.
