ORB
(ORB) Part of the OMG CORBA specification,
an ORB's basic function is to pass method invocation
requests to the correct objects and return the results to
the caller.
To achieve this the ORB must be able must be able to identify
and locate objects, handle connections from invoker and the
data returned from methods. Communication between the ORB and
applications are achieved through IDL stubs and skeletons
whilst the OMG has specified IIOP as the protocol through
which ORBs may communicate with each other. Using IIOP, an
ORB may request method invocations from a remote object.

CORBA
(CORBA) An Object Management Group
specification which provides a standard messaging interface
between distributed objects.
The original CORBA specification (1.1) has been revised
through version 2 (CORBA 2) with the latest specification
being version 3 (CORBA 3). In its most basic form CORBA
consists of the Interface Definition Language (IDL) and the
Dynamic Invocation Interface (DII).
The IDL definition is complied into a Stub (client) and
Skeleton (server) component that communicate through an
Object Request Broker (ORB). When an ORB determines that a
request is to a remote object, it may execute the request by
communicating with the remote ORB.
The Corba IDL can be mapped to a number of languages including
C, C++, Java, COBOL, Smalltalk, Ada, Lisp,
Python, and IDLscript. CORBA ORBs are widely available
for a number of platforms. The OMG standard for inter-ORB
communication is IIOP, this ensures that all CORBA 2
compliant ORBS are able to interoperate.
