  Darwin
       n 1: English natural scientist who formulated a theory of
            evolution by natural selection (1809-1882) [syn: {Charles
            Darwin}, {Charles Robert Darwin}]
       2: provincial capital of the Northern Territory of Australia



From The Free On-line Dictionary of Computing (27 SEP 03) [foldoc]:

  Darwin
       
          1.  An {operating system} based on the
          {FreeBSD} version of {Unix}, running on top of a {microkernel}
          ({Mach} 3.0 with darwin 1.02) that offers advanced networking,
          services such as the {Apache} {web server}, and support for
          both {Macintosh} and Unix {file systems}.  Darwin was
          originally released in March 1999.  It currently runs on
          {PowerPC} based Macintosh computers, and, in October 2000, was
          being ported to {Intel} processor-based computers and
          compatible systems by the Darwin community.
       
          2.  A general purpose structuring tool of
          use in building complex {distributed systems} from diverse
          components and diverse component interaction mechanisms.
          Darwin is being developed by the Distributed Software
          Engineering Section of the Department of Computing at
          {Imperial College}.  It is in essence a {declarative} binding
          language which can be used to define hierarchic compositions
          of interconnected components.  Distribution is dealt with
          orthogonally to system structuring.  The language allows the
          specification of both static structures and dynamic structures
          which evolve during execution.  The central abstractions
          managed by Darwin are components and services.  Bindings are
          formed by manipulating references to services.
       
          The {operational semantics} of Darwin is described in terms of
          the {Pi-calculus}, {Milner}'s calculus of mobile processes.
          The correspondence between the treatment of names in the
          Pi-calculus and the management of service references in Darwin
          leads to an elegant and concise Pi-calculus model of Darwin's
          {operational semantics}.  The model has proved useful in
          arguing the correctness of Darwin implementations and in
          designing extensions to Darwin and reasoning about their
          behaviour.
