About UUIDs
A UUID (Universally Unique Identifier) is a 128-bit number used to uniquely identify information in computer systems. The probability that a UUID will be duplicated is not zero, but it is close enough to zero to be negligible.
UUID Versions:
Version 1 (Time-based)
Generated using a timestamp and the MAC address of the computer. This version is predictable and may reveal information about the system that generated it.
Version 4 (Random)
Generated using random or pseudo-random numbers. This is the most common version used when uniqueness is the primary requirement.
Common Uses:
- Database keys
- Session identifiers
- Transaction IDs
- Unique identifiers for distributed systems
- Tracking cookies
