What is a UUID

A UUID (Universally Unique Identifier) is a 128-bit number used to uniquely identify information in computer systems. It is standardized by the Open Software Foundation (OSF) as part of the Distributed Computing Environment (DCE) and specified in RFC 4122. The primary purpose of a UUID is to provide a unique identifier that can be used across different systems without requiring a central coordinating authority.
