GUID (Globally Unique Identifier) is a 128-bit unique identifier used to identify objects in computer systems. It is generated in such a way that the likelihood of two GUIDs being identical is almost zero, making it ideal for use in distributed systems and databases. A GUID consists of 32 hexadecimal characters, separated by dashes, and is often used for the unique identification of records or objects.
