What is a GUID?
The terms GUID and UUID can be used interchangeably, While UUID is used everywhere else, the word GUID is typically used by developers who work with Microsoft technologies. They represent, respectively for C# GUID or globally unique identification and Java UUID or universally unique identifier.
A GUID uniqueidentifier is a 16-byte long, 128-bit integer whose value has a particular structure. The creation of GUIDs will produce unique results when employing a conventional procedure. Although it is feasible, the chances of doing so are extremely slim.
How unique are GUIDs and UUIDs?
Technically, despite the lack of a central GUID authority to guarantee uniqueness, they are 128-bit unique reference numbers used in computation that are extremely unlikely to duplicate when created.
Statistics show that GUIDs are unilateral. It is extremely unlikely that two separate clients will generate the identical Guid (assuming no bugs in the Guid generating code). No, they are not special in theory. It is feasible to repeatedly produce the same guid. But since the likelihood of it happening is so slim, you may presume they are one of a kind.
