Generate a Universally Unique Identifier (UUID) - 128-bit 36-character string of as a unique number used to indentify information in computer systems. The string contains hexadecimal digits and hyphens.
To create uniqueness UUID v1 is generated using the current date and time and using the host computers MAC address and another random component to create its uniqueness.
There is no inherent logic used to generate a UUID using V4. The bits that comprise a UUID V4 are generated randomly with no way to identify information about the source.
