What is UUID?

A universally unique identifier (UUID) is a 128-bit number used to identify information in computer systems. The term globally unique identifier (GUID) is also used.

UUIDs are used in various applications to ensure unique identification without the need for a central registration authority. They are critical in distributed systems, databases, and software development.
