What is a GUID?

The word is an acronym for 'Globally Unique Identifier', which is used to describe a 123-bit integer number that has been generated at random. Microsoft technologies tend to use the term GUID while others use UUID or 'Universally Unique Identifier'.

While the value is described as "unique" it could always be randomly generated by a computer twice. Though the possibility of this happening is only a reality in 10 million + range.
