I very freely admit that I have significant gaps in my knowledge of all things computer-related. For example, I have only rudimentary understanding of TCP/IP.
But one thing has been bothering me lately, and while I realize that this question is probably the computational equivalent of "why is the sky blue?" in meteorology, I'll ask it: Why does it take so long for an OS to boot, and also a long time for it to shut down? Or, if the general case is too hard to answer, then I'll ask specifically: Can anyone explain to me why it takes so long for MSWindows to boot? I mean, I realize that there's lots of device drivers to load, but should it really that that much longer for MSWindows to load than it takes for any other large program, like MSWord?
And especially for shutdown: if I have no applications open, why does it take more then 2 or 3 seconds to shut the machine down?
