[QUOTE=Uncwilly;235860]An item that is part of a computer (in the chips), isn't "connected" to it, it is it. I think some of the questions that lead up to that are the problem, directing thoughts.[/QUOTE]Sure it is, the alternative is not connected, and they are not not connected. I did however say "connected" to imply that it was perhaps misleading to characterise them as such, but I couldn't exactly spell it out without giving too much away. Nevertheless, I'm sure there are some quad NAND chips soldered onto motherboards somewhere.

Indeed. Thanks.
