+A Globally Unique Identifier (GUID) is a 128-bit number designed to uniquely identify information in computer systems. Its primary purpose is to ensure that each [Identifier](/wiki/identifier) is distinct across all possible instances, especially crucial in [Distributed System](/wiki/distributed_system)s where collisions must be avoided. Generated with high randomness, it provides a universally unique label for any entity.
