Ribbon cable? You mean this?:
It's called an IDE cable, some call it ATA or PATA. It's an older version of connection with slower speed. But for an ODD, this won't matter much. For the HDD however, the speed difference is quite significant. The maximum is 133 MB/s, compared to SATA II's 3GB/s. You'll notice it when transferring bulk data. I suggest stick with the SATA, unless you're a very patient guy.
Besides, your mobo only have 1 IDE port, it's wise to use it for the ODD rather than the HDD.
Nothing to worry about. The stupidest is the one who doesn't know but doesn't want to ask either. Nothing's too silly in regards to learning.
