Norton Ghost

So, whats the difference between Norton Ghost and Windows system restore? Aside from the hard drive copying.

What I'm asking is, specifically what it is meant by the term "Ghosting"? Also any in depth detail on what else it does.

So ghost uses a floppy disk to bootup and restore when you just can't possibly get back...I see. That is pretty useful. Thanks >>2 Just one more thing, can ghost do the same thing as system restore? What I mean is, lets say I want to upgrade firefox and it doesn't work anymore, and I want my original setting of firefox. Does it do that?
