About UUID Generator
What is a UUID?
A UUID (Universally Unique Identifier) is a 128-bit label used for information in computer systems. The term GUID (Globally Unique Identifier) is also used. The probability of finding a duplicate UUID is close to zero, making them ideal for identifying resources without a central coordination authority.
