What is a UUID?
A UUID (Universally Unique Identifier) is a 128-bit identifier that is unique across all devices and time. UUID v4 uses random numbers, making collisions virtually impossible. UUIDs are commonly used as database primary keys, session tokens, and unique identifiers in distributed systems.
