- Globally unique identifier

| rdfs:comment | - A globally unique identifier (GUID) is embedded in most computer hardware and some computer software. GUIDs were initially developed to provide security by removing the anonymity protection of malicious users. Because GUIDs were embedded in hardware, they could not be removed or altered by the user. However, the actual uses of GUIDs quickly because twofold. First, they were used by marketers to track user's online habits, much in the way a cookie is used. Second, some of the major software companies retain GUID information about Internet users, for reasons that have not been disclosed.
- A Globally Unique Identifier or GUIDis a special type of identifier used in software applications in order to provide a reference number which is unique in any context (hence, "Globally"), for example, in defining the internal reference for a type of access point in a software application, or for creating unique keys in a database. While each generated GUID is not guaranteed to be unique, the total number of unique keys (2128 or 3.4×1038 is so large that the probability of the same number being generated twice is very small. For example, considering the observable universe contains about 5 × 1022 stars, every star could have a GUID (though there would still be a collision due to the birthday paradox).

The term GUID usually refers to Microsoft's implementation of the Universally Unique Identifier (UUID) standard; however, many other pieces of software use the term GUID including Oracle Database, dBase, OpenView Operations, and Novell eDirectory. The GUID is also the basis of the GUID Partition Table, Intel's replacement for Master Boot Records under EFI.
