Based on a different software architecture, ## sure. But it's UNIX. ## ## Windows/NT is based on a Mach kernel... (as discussed in comp.os.mach) Sorry, but that's NOT "in fact". While Windows/NT borrows from Mach the idea of a kernel supporting multiple protected mode subsystems each of which supports a distinct service model, NT doesn't use any code from Mach. Go and read "Inside Windows NT" by Helen Custer (1993, Microsoft Press, ISBN 1-55615-481-X). NT != UNIX (for all values of UNIX). Internally, NT probably borrows more from VMS than anything else - after all, Cutler always wanted a chance to redo VMS "right". --- Geoff Arnold, PC-NFS architect, Sun Select.
