GUID (Globally Unique Identifier)

A GUID (Globally Unique Identifier) is a distinctive string of characters used to identify information in computer systems, ensuring no two are alike. Think of it as a unique digital fingerprint for objects like files, records, or devices. GUIDs are generated using complex algorithms that incorporate factors like time, hardware, and randomness, making it practically impossible for duplicates to occur worldwide. This uniqueness helps software applications reliably track, manage, and reference items without confusion or overlap, supporting data integrity and security across various systems and networks.
