About UUIDs
UUID (Universally Unique Identifier) is a 128-bit identifier used to uniquely identify information. UUID v4 is randomly generated, while UUID v5 is generated from a namespace and a name using SHA-1 hashing.
UUIDs are commonly used in databases, APIs, and distributed systems to ensure unique identifiers across different systems.
