Or I could argue that I could ultimate find the capacitors and transistors for anything else we're talking about here. Except if they're just transistors because the representation of the pipe is sitting in static RAM for some reason, or in the fluctuation of a magnetic field. Or all of the above at the same time (caches, page files). Which one is the "real", non-metaphorical representation of the pipe? The one in the cache because it's being worked on by the CPU? The one in memory because its lifetime is longer?
