What is a UUID used for?
Uniquely identifying records, sessions, or objects in databases and distributed systems without central coordination.

    
What's the difference between UUID versions?
v4 is randomly generated (used here); other versions incorporate timestamps or namespaces for different use cases.

    
Can two UUIDs ever collide?
Theoretically possible but practically negligible — v4 UUIDs have 122 random bits, making collisions extremely unlikely.
