What is a GUID ?

GUID is an acronym which stands for 'Globally Unique Identifier'. A GUID is a 128-bit integer number and usually is used to identify resources in computer systems. The term GUID is used by software developers using Microsoft technolgies, while UUID is used in other places.

How unique is a GUID ?

The algorithm for generating a unique 128-bit integer number (GUID) is good enough so that if for example you generate 1,000,000,000 GUIDs per second for 85 years year the probability of a duplicate would be only 50%. Thus the smallest number of generated GUIDs for the probability of finding a duplicate is 103 trillion and the probsability is one in a billion.
