About UUID

UUID (Universally Unique Identifier) or GUID (Globally Unique Identifier) is a 128-bit number used to identify information in computer systems.

UUID v4 is randomly generated and has 2^122 possible combinations, making collisions extremely unlikely.

UUIDs are widely used in databases, distributed systems, and software development for unique identification without central coordination.
