Uuid Generator Description

What is a UUID?

A Universally Unique Identifier (UUID) is a 128-bit number used to identify information in computer systems. UUIDs are generated randomly and are highly unlikely to be duplicated, making them ideal for use as unique identifiers in databases, software development, and more.

UUIDs are standardized by the RFC 4122 specification, which defines different versions of UUIDs, including version 4, which is the most commonly used version and is generated randomly.
