UUID
Distinct digital fingerprint
UUID stands for universally unique identifier—a 128-bit label used in computing to identify information without requiring central coordination.
The format is a string of hexadecimal digits typically displayed with hyphens: 550e8400-e29b-41d4-a716-446655440000.
UUIDs let systems generate identifiers independently with near-zero probability of collision, making them essential for distributed databases, session tokens, and software components that need unique references.
