A UUID (Universally Unique Identifier) is a 128-bit value used to uniquely identify information in computer systems.

What is the difference between UUID v1 and v4?

UUID v1 is based on timestamp and MAC address, while UUID v4 is generated using random numbers, making it more secure and commonly used.

Why use a UUID generator?
