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 Active Directory.See also attribute.
object identifier (OID)
An extensible, unique identification number for attributes and classes. Performance counter names have their own object identifiers, which are listed in Management Information Base (MIB) files, to provide performance monitoring applications with access to the counters.See also Management Information Base (MIB).See also Simple Network Management Protocol (SNMP).
Object Linking and Embedding (OLE)
A set of integration standards for transferring and sharing information among client applications. Also, a protocol that enables the creation of compound documents with embedded links to applications, so that a user does not have to switch among applications to make revisions. OLE is based on the Component Object Model (COM), and it enables the development of reusable objects that operate across multiple applications.
Object Linking and Embedding Database (OLEDB)
Data-access interfaces that provide consistent access to Structured Query Language (SQL) data sources and non-SQL data sources across an organization and the Internet.See also structured query language (SQL).
object-cache scavenger
The code that periodically scans the cache for objects to be discarded. It deletes files that have not been used recently and therefore are unlikely to be used again in the near future.
octet
In programming, an octet refers to eight bits or one byte. IP addresses, for example, are typically represented in dotted-decimal notation; that is, with the decimal value of each octet of the address separated by a period.
ODBC
See Open Database Connectivity (ODBC).
OID

Open Database Connectivity (ODBC)
An application programming interface (API) that enables applications to access data from a variety of existing data sources. A standard specification for cross-platform database access.
out-of-process
For IIS 5.0 isolation mode, ISAPI extensions that are hosted in a surrogate process called DLLHOST.exe, which is managed by COM+.See also IIS 5.0 isolation mode.
out-of-process component
A Component Object Model (COM) component that runs in a separate process space from its client.See also process isolation.
