GUIDs are used in many pieces of software, including Oracle Database and Novell eDirectory, but the most high-profile GUID implementation may be Microsoft's.
GUIDs are also inserted into documents from Microsoft Office programs, as these are regarded as objects as well.
In these (V1) GUIDs, the user's network card MAC address was used as a base for the last group of GUID digits, which meant, for example, that a document could be tracked back to the computer that created it.
A GUID is 16 bytes long which is four times as long as an INTEGER.
GUIDs provide a more object oriented approach to database management because each primary key in each table will be unique for the entire database.
The post asserts that GUIDs are made of random numbers, plus date and time to a 1/300th of a second.

RSS 2.0 Specification(Site not responding. Last check: 2007-11-07)
If the guid element has an attribute named "isPermaLink" with a value of true, the reader may assume that it is a permalink to the item, that is, a url that can be opened in a Web browser, that points to the full item described by the element.
If its value is false, the guid may not be assumed to be a url, or a url to anything in particular.
However, in other systems, each is a synopsis of a longer article, points to the article, and is the permalink to the weblog entry.
For instance, a Web site may generate a GUID and assign it to a user's browser to record and track the session.
A GUID is also used in a Windows registry to identify COM DLLs.
GUIDs can be created in a number of ways, but usually they are a combination of a few unique settings based on specific point in time (e.g., an IP address, network MAC address, clock date/time, etc.).

To use this application, click on the Generate GUID button.
Your GUID (globally unique identifier) will appear in the text box.
GUIDs are frequently used in software development to provide unique identification of software objects such as components, code modules, and data structures.
A GUID is a Globally Unique Identifier, basically a 16-Byte string that is guaranteed to be unique.
There is a simple function that allows you to create a GUID that uses the Windows API to guarantee it's unique.
The component used by this function (scriptlet.typelib) is installed as a part of the microsoft scripting engines and therfore should always be availible to you.
A GUID framework is foundational in facilitating systems interoperability in biodiversity informatics.
A GUID framework will help to manage and cross-link the many different types of entities that are manipulated analytically in biodiversity informatics and will improve interoperability with other related life sciences domains, such as bioinformatics and ecology.
Clarify the distinction between GUIDs assigned to data objects and to conceptual entities.
MSN Cookie Data Crosses Domains(Site not responding. Last check: 2007-11-07)
Because the GUID is part of all URLs on the bCentral.com domain whenever cookies are disabled, it will also be included in any bookmarks (favorites) or shortcuts the user may create.
This demonstrates that the GUID that's being set and/or utilized by msid.msn.com and passed to other domains is the very same one MSN uses routinely to identify its portal users.
Again, the GUID is passed by the same technique and an MSNBC cookie is created, containing the same GUID as the MSN cookie.

UUID (GUID) Generator on the WEB(Site not responding. Last check: 2007-11-07)
This UUID is generated according to RFC 4122 Using the timestap / nodeid version (version 1), where the nodeid comes from network equipment I own.
This type of UUID is generated using the current time, a clock id which changes in case the current time is found to be older than the latest known time a UUID is generated and an IEE 802 hardware address which should be unique.Still the following disclaimer applies:
The provided UUID (GUID) is provided AS IS without warranty of any kind, not even the warranty that the generated UUID is actually unique.
Of course, a GUID isn't personally identifiable information in itself, and you don't generally tell Google your name, address or telephone number.
If you check that setting, for some services the Google server will use a checksum to reset your zeroes to something unique (you should try with and without, to see if the modest functionality enhancements are worth it for you).
I heard about using a cookie GUID to latch on to a Google design limited release[i] from Jesse Ruderman's terrific site/blog, and slightly adapted this Bookmarklet to suit this anonymizing tweak.
Statewide faculty groups representing the two- and four-year public institutions will be encouraged to develop and recommend broad guidelines for the standards of general education courses in the five specified areas.
The recommendations from these groups will be forwarded to the CAO group for agreement, implementation, and inclusion in the Guiding Principles.
In a given discipline, there may be multiple courses that can satisfy all criteria for general education courses and therefore any one of which can be used to satisfy a general education requirement for that discipline/area.

addEvent() - My Solution(Site not responding. Last check: 2007-11-07)
The $$guid thing is different and like I said a good idea, but it leaves you with the problem with prototyped methods - you will need to check for those in your for-in and skip them, or iterate in a different way.
The first one is easy enough to fix (delete handler.$$guid;), but the second requires that the handler function contain a hashtable of elements and guids (or some such).
The $$guid is just created to uniquely identify a function that has been used as a handler.
MS Media Player GUID is a warning that the Window Media player may transmits an anonymous Global Uniquie IDentifier (GUID) to the streaming servers when you download content.
The existance of this ID in the registry does not imply that it is transferred to web sites to distinguish a user, but I recommend to check the Media Player settings and then remove the ID as outlined below.
In order to provide correct, accurate and updated information about MS Media Player GUID I encourage the vendor to contact me if any part of this write-up needs a revision.
The reason for sending GUID is because GUID is much safer than sending other values.
There are more secure ways of handling the transfer than sending a GUID in the QueryString.
For one thing the URL might be saved in the browser history which is a big problem if the user is at a public computer and there is sensitive information on the site.
