Which of these two is the correct term: Named Parameters or Named Arguments?

As for C # 4.0, which of these two is the correct term: Named Parameters or Named Arguments? I find many cases of both terms, so I'm rather confused how to mention them (say, in the official documentation)?

Parameters

have always been named; in the context of providing values ​​for a method, they are arguments — however, then the name you specify is the name of the parameter. Therefore, I see how this will be confused, but in the context we provide a name for the compiler to resolve the argument, so ftw is called named arguments.
