We just added a new article - Understanding Audio and Video Wire and Cable
It is a tutorial on Audio and Video Cables, from a slightly technical perspective, although we try to explain things in mostly laymen's terms with examples and clear, easy to understand specifics on the differences of varying cable parameters. It is not a FAQ, but more or less an overall tutorial. We hope it's easy enough to read and learn from. Please comment and we'll fix it too your liking.
In any case, why not take a shot and see if you can add a bit to your cable IQ?
