About UUIDs
A UUID (Universally Unique Identifier) is a 128-bit number used to identify information in computer systems. UUIDs are standardized by the Open Software Foundation (OSF) as part of the Distributed Computing Environment (DCE).
Version 4 UUIDs are randomly generated and are the most common type.
Version 1 UUIDs are based on the current timestamp and the MAC address of the computer generating them.
