What is GUID?
Definition
GUID (Globally Unique Identifier) is Microsoft's term for UUID. GUIDs and UUIDs are technically identical — both are 128-bit identifiers in the same format. The term GUID is common in .NET and Windows ecosystems.
Why It Matters
If you work with Microsoft technologies (.NET, SQL Server, Azure), you will see GUID used instead of UUID. They are interchangeable — a UUID generated in Python is valid as a GUID in C# and vice versa.
