Generate GUID (Globally Unique Identifier)
What is a GUID?
A GUID (Globally Unique Identifier) is a 128-bit number used to uniquely identify information in computer systems. GUIDs are particularly useful when you need a unique identifier that’s guaranteed to be different from any other, across space and time, without relying on a central authority.
🔑 Key Characteristics of GUIDs:
- Length: 128 bits (usually displayed as 32 hexadecimal characters).
- Format: Commonly written in 5 groups separated by hyphens.
- Used in: Databases (as primary keys), Software development (to identify objects, components, sessions), Distributed systems (to ensure uniqueness without coordination)
