My friend as I had an argument yesterday over what DIMM meant. I thought it was Digital Integrated Memory Module. I learned that in a class I'm taking. Granted, its a Graphic Design class, but I do think they would get that right at least... My friend got all huffy and said I learned it wrong and that it was Dual In-line Memory Module, which I later confirmed online. I had an idea that maybe DIMMs had a different meaning in the Mac world (by friend is a big peecee buff). I was just wondering what this means. Did I really learn it wrong? Or is it both? Are they compeltely different things? Please clarify! Thank you.
