Question 1

What is a UUID?

Accepted Answer

A UUID (Universally Unique Identifier) is a 128-bit number used to uniquely identify resources. Version 4 UUIDs are randomly generated and have a near-zero chance of collision, making them ideal for distributed systems.

Question 2

How many UUIDs can I generate at once?

Accepted Answer

You can generate up to hundreds of UUIDs in a single click. Each UUID is cryptographically random and RFC 4122 compliant. Use bulk generation for database seeding, testing, and batch operations.

Question 3

What is the difference between UUID and GUID?
