The Crucial advisor suggests CT1018273, a 2GB memory upgrade for my Samsung NP-N120 netbook. I see that Crucial also offer a CT25664AC800 which appears to be identical. Am I missing something? What differentiates these parts?
The two parts are basically the same. When you order online by system information, you are shown what we refer to as an “external” part number, in your case number CT1018273. It is a system specific number and is mapped exclusively to the Samsung N120. The longer part number, CT25664AC800, is the one that would you see printed on your module, and that is the actual module part number, or the "base" part number.
There are other specifications to memory than the basic ones published on the site, and they sometimes requires us to filter out a certain build of a part for a specific system. The external part number can accomplish this, since we can build filters into them when necessary. Those filters are also the reason that we can only guarantee compatibility if you order by system; the external part number tells us which computer you are ordering for. If you order by specifications we don't know what model of computer you have, and that makes it impossible to guarantee compatibility.
I hope this helps!
