O
object application :
An application that acts as a server to provide various data objects to be
included in a compound document.
object :
A combination of code and data that can be treated as a unit; for example,
a control, form, designer, or application. Each kind of object is defined
by a class.
COM objects and objects in object-oriented programming. In object-oriented
programming, an object is an entity that has state, behavior, and
identity. Its state consists of its attributes and the current values of
those attributes. An object’s behavior consists of the operations that can
be performed on it and the corresponding changes in its state. An object’s
identity distinguishes it from other objects.
In contrast, a COM object’s behavior is defined by the interfaces it
supports. A COM object’s state is not explicitly specified, but is implied
by its interfaces. A COM object’s identity is defined by the ability to
use IUnknown::QueryInterface to move between interfaces.
A COM object follows a specific model in which clients (those using an
object’s services) gain access to the object’s data only through a pointer
to an interface consisting of a set of methods (related functions). The
client can then call these methods to perform desired operations.
