What is GUID?

A GUID (Globally Unique Identifier) is like a super unique code. Imagine it as a very special ID number that is 32 letters and numbers long, and it looks something like this: 550e8400-e29b-41d4-a716-446655440000. This code is so special that no two are the same, kind of like how no two people have the same fingerprint.

People use GUIDs in computers and the internet to make sure everything has its own unique tag, so there's never any mix-up.
