O


object

An entity, such as a file, folder, shared folder, printer, or Active Directory object, described by a distinct, named set of attributes. For example, the attributes of a File object include its name, location, and size; the attributes of an Active Directory User object might include the user's first name, last name, and e-mail address.

For OLE and ActiveX, an object can also be any piece of information that can be linked to, or embedded into, another object. See also attribute; child object; parent object.

object linking and embedding (OLE)

A method for sharing information among applications. Linking an object, such as a graphic, from one document to another inserts a reference to the object into the second document. Any changes you make in the object in the first document will also be made in the second document. Embedding an object inserts a copy of an object from one document into another document. Changes you make in the object in the first document will not be updated in the second unless the embedded object is explicitly updated.

See also fault tolerance; mirrored volume; RAID-5 volume.
