About UUID

UUID (Universally Unique Identifier) is a 128-bit number used to identify information in computer systems. It is a widely used standard for identifying objects in distributed systems. A UUID is assigned to an object when it is created and is used to identify the object in subsequent interactions. UUIDs are used to identify objects in a wide range of systems, including computer hardware, software, and networks.
