This is a simple online tool for generating globally unique ids (GUIDs) aka universally
unique ids (UUIDs).
What is it used for:
A GUID represents a Unique identifier - means you cannot generate the same GUID
more than once. A GUID has a very low (...practically impossible) probability of
being duplicated. GUIDs are applied for identification purposes in a number of fields
in the computer industry.
Possible uses are (but are not limited to):
- The identifiers in the windows registry.
- Identifiers used in databases.
- Identifiers used in RPC (COM, CORBA) (remote procedure calls)
- To ensure nobody else would - by accident - provide something conflicting.
GUIDs can be generated in a number of ways; most often a hash of several things
that might be unique at any given point in time like the IP address plus the clock
date/time etc are used to generate Unique Ids. Each system may have slightly different
algorithm to generate the Unique Id.
