o_o I'm going to say I think i understand all of this.

My CPU usage right now is about 10 to 25 percent. I'm running sidebar, AIM, MSN, Firefox, and probably some other things. (and as I typed this jumped up to 100, and Norton says something about checking stuff).
My physical memory was 49, now 52, but still hasn't reached very high.

I don't know how many cores i have. I have AMD Turion 64x2. Or so says the sticker still on my computer (Yes I really still have the sticker, though this year it has been slowly losing the clear cover on it).
