Glossary
access control policy - Specifies which users are or are
not entitled to an application's services.
authentication - Clients and servers capable of proving
their identities to each other.
authorization - Means of access to information managed
based on identity of the user.
automation - OLE mechanism to allow an application to control
another application directly.
binding - The act of associating a server with a socket.
Logical association between a client and a server.
bridging - A mapping between two domains.
broker or binding service - An intermediary between clients
and servers designated to assist in network resource communications.
client application - A user-written program that performs
function calls to be executed by a server application.
client process - A process that executes the client application.
client/server model - Processing environment where one
set of entities requests work to be done
and another set actually performs the work.
client stub - Code module that is generated by the special
Newark interface compiler. A client stub provides:
- filters to encode and marshal the IN arguments
- a call to the requested server
- filters to unmarshal and decode the reply OUT arguments
- time-out of the operation if needed
CORBA2/Interoperable - CORBA2/Core and the CORBA2/Internet
IOP
domain - A set of objects sharing a common characteristic
or abiding by common rules.
embedding - OLE technique that allows a container document
to completely hold another COM object.
interface - The collection of remote procedures that a
client and server share.
linking - OLE technique that allows a container document
to hold a reference to another COM object. The object itself is
extenal to the container document.
marshaling - Packaging the input parameters and sending
them to the remote process.
NIS - Stores network information on servers and provides
it to any workstation that asks for it.
OSF - A consortium of DEC, IBM, HP/Apollo, and other major
UNIX
hardware vendors.
port - a logical network communication channel.
server application - A user-written program that handles
and replies to request(s) from a client application.
server process - A process that executes the server application.
server stub - Code module that is generated by the special
network interface compiler. A server stub provides:
- registration of the service with the proper lookup utility
- filters to unmarshal and decode the IN arguments
- invocation of service routine requested
- filters to encode and marshal the OUT arguments
- results back to client
unmarshaling - Unpacking the input parameters and calling
the requested procedure using the unpacked arguments.
