A unique number that identifies a servlet object and is used to request that Netscape Application Server runs that servlet.

A 16-byte value generated from the unique identifier on a adapter, the current date and time, and a sequence number. This is used to allow any party to create identifiers that will be guaranteed not to overlap with other similarly created identifiers.

An identifier of an entity, such as persistent document, that has been generated by an algorithm guaranteeing its global uniqueness.

A 16-byte value that uniquely identifies something, usually the software that implements one or more COM objects or an interface on one of those objects.

The unique identifier of OLE objects or servers, including ActiveX controls. Your control's GUID is assigned to it by Visual Basic at the time it is compiled.

A unique 128-bit number assigned to a school to distinguish it from other schools

A 16-byte value generated from the unique identifier on a device, the current date and time, and a sequence number. A GUID is used to identify a particular device, component, user, or session.

A 16-byte code that identifies an interface to an object across all computers and networks. The identifier is unique because it contains a time stamp and a code based on the network address that is hard-wired on the host computer's LAN interface card.

A Globally Unique Identifier or GUID (IPA pronunciation: or ) is a pseudo-random number used in software applications. While each generated GUID is not guaranteed to be unique, the total number of unique keys (2128 or 3.40282366×1038) is so large that the probability of the same number being generated twice is very small. For an application using 10 billion random GUIDs, the probability of a coincidence is on the order of 1 in a quintillion.
