@LauriRanta: thanks for the hint. Should I mark the question for deletion, since it's basically a duplicate? – Scarlet May 3 '13 at 12:51

Wired memory is pretty much memory that the operating system has taken control of and wont let anyone else have. So the system takes what it needs and holds it. And Inactive memory is memory that a program has recently used but is not currently using. This memory sometimes allowes functions that repeat in process to run better. Source
