- An identifiable, encapsulated entity that provides one or more
services on request; entities in a distributed computer environment
that are being managed; a model of the physical resources that are
to be managed.
- object adapter
- Routines which provide an interface to ORB
services that is convenient for a particular style of object
implementation. There are several kinds of object adapters, for
example the Basic Object Adapter (BOA),
the Library Object Adapter (LOA), and the
Object-Oriented Database Adapter.
- object group
- A named logical entity to which one or more objects belong and
over which an administrator is granted one or more roles.
- object implementation
- The provider of a service for a requestor
(client); the Server.
- Object Management Group (OMG)
- Object Management Group, Inc. is a non-profit international
association of over 300 companies headquartered in Framingham, MA,
whose goal is to define an architectural object framework through
a series of detailed interface specifications.
- Object Request Broker (ORB)
- Delivers a request from a client to an object implementation.
ORB provides the mechanisms by which objects transparently make
requests and receive responses, providing interoperability between
applications on different machines in heterogeneous distributed
- object type
- A set of objects that share a common interface; the characteristics
that are common to a group of objects.

- Open Shortest Path First (OSPF)
- A routing
protocol where a route is chosen based on the fewest number
of hops that do not pass through an over-congested router or network.
- Open Systems Interconnection (OSI)
- A model for implementing the protocols and interfaces to facilitate
communications among computers of different manufacture and technology,
being a seven-layer structure of (from lowest to highest) physical,
data link, network, transport, session, presentation, and application.
- operating system (OS)
- The computer program or set of instructions that defines how a computer
should operate. The underlying program running on a computer that allows
the scheduling of jobs and the sharing of various system resources such as
memory, disk space, and printers.
