I've been talking with a computer science professor at my university about Mac OS X and he asked me if the kernel was single server UNIX or multi-server. Can anyone help me out? I have no idea what he's talking about. =) Thanks. There's some confusion here, I think. The 'single-' vs. 'multi-' server issue arises because of the fact that Mac OS X uses Mach in its underpinnings (the Darwin OS). However, unlike the more 'academic' uses of Mach (ignoring OS/1), Mac OS X does not have a server-based OS. The Mach implementation is tightly integrated with the rest of the (BSD-based) OS, and there is no attempt to run operating systems as "server processes". Although Darwin/Mac OS X uses Mach 3.x, it is implemented in a way that is closer to Mach 2.x. That may help discuss this with your prof. Regards, Justin -- /~\ The ASCII Justin C.
