About GUIDs

What is a GUID?

A GUID (Globally Unique Identifier) is a 128-bit number used to uniquely identify information. GUIDs are the Microsoft implementation of UUIDs (Universally Unique Identifiers) and are widely used in Windows and .NET applications.

GUID vs UUID

GUIDs and UUIDs are essentially the same thing. The term "GUID" is primarily used in Microsoft technologies, while "UUID" is the standard term used in most other contexts. Both follow the RFC 4122 specification.
