Since I've joined MacRumors, I've thought of so many questions that I've always wondered the answers to. I'm a newbie but I've worked with macs for years (I had a IIsi with 8mb of RAM), but I don't know the difference between normal desktops and the servers. What does a server do that a normal desktop can't? I know this sounds like a stupid question, but the answer kinda stumps me. Thanks everyone for all of the information. I've learned more in the past three weeks that I did in the past five years.
