GUID Introduction
What is GUID
GUID (Globally Unique Identifier) is Microsoft's implementation of the UUID standard, a 128-bit number usually represented as 32 hexadecimal digits, separated by hyphens in 8-4-4-4-12 format.
GUID vs UUID
GUID is Microsoft's implementation of the UUID standard. They are technically the same, but GUID is more commonly used in Windows systems and .NET development.
GUID Structure
GUID consists of 32 hexadecimal digits, usually divided into 5 groups: 8-4-4-4-12, for example: 550e8400-e29b-41d4-a716-446655440000
Uniqueness Guarantee
GUID uses timestamp, random numbers and hardware information to ensure global uniqueness with extremely low probability of duplication.
