you're not missing much in "formal schooling". I've been here for 3 years now and don't feel i've learned anything new since i've come, except of course what i've done on my own. If u sift around in some A+ guides, either online or at your favorite book store, i'm positive you'll be able to find the answer you're looking for. You'll even learn about the differences in micron sizes, PGA's, word sizes/bits, etc... good luck
