File systems. It may seem obvious, but I'm not sure how clearly we associate them with the originals. We take the file systems of Windows and *nix etc for granted, but they are essentially computerised versions of the physical classification systems that go back as far as humans have wanted to categorise things and put them in related boxes and particular orders. I feel like that's cheating though, as by the same mapping process we get mail networks etc
