Frequently asked questions

  1. What is a GUID?
    A GUID is a unique identifier on 128 bits
  2. For what stands GUID and UUID?
    GUID stands for Globally Unique Identifier and UUID stands for Universally Unique identifier.
  3. What is the difference between GUID and UUID?
    They are the same thing. GUID is the acronym used by Microsoft developers for UUID.
  4. Is a GUID 100% unique?
    No, but is almost impossible to generate the same UUID. If you generate for every second 1 billion of GUIDs after ten years will be a probability of 50% to generate a UUID already generated.
  5. How are generated?
    All UUIDs are randomly generated but based on the same conditions. There are four versions to build a guild, some use the MAC address of the computer. The last version uses a random number generator that is based on a pseudo algorithm.
  6. How many unique identifiers can generate in a single round on Randommer?
    You can generate up to 10000 random identifiers once but you can retry for how many times you want.
