The code in the Darwin kernel is in several "components":
  - BSD: much of the kernel functionality (system calls,
         networking, file systems) is here
  - Mach: derived from Mach 3.x, but integrated with the
          rest of the OS like Mach 2.x; this component
          handles tasks, threads, memory management, and
          messaging (some, but not all, of the communication
          within Mac OS X/Darwin is done with Mach
          messages)
  - IOKit: the device driver/device support component.  An
          object-oriented environment, based more or less
          on embedded C++

There are some other, more minor pieces (platform expert, libsa, libkern), but the above three make up the lion's share of the kernel.  In addition to the kernel, functionality is provided by loadable extensions (KEXTs); these include networking components (NKEs), file system plugins, and device components (drivers, family support, ...).

If you know FreeBSD 4.x, you may be able to recognize most of the BSD part.  The networking component is changed in some significant ways, at different layers.  The IP stack is more or less the same, but the area where stacks meet devices is much different.  I don't know FreeBSD 5.x well enough to comment on how it matches Darwin.
