Which is guarenteed to be unique. It's really a big-ass number that's
encoded in hexidecimal, and then split with three dashes, but for all
intensive purposes you can consider it a string. They are generated from
several inputs, a psuedo-random number generator (PRNG), the MAC address of
the host machine, and a timestamp. There might be others, and I believe
they don't have to use the MAC address, in situations where it's not
available. If you need that detail, read the RFC Jochem provided.
They are useful for generating unique keys whne you don't want the keys in
sequential integer order like a RDBMS would generate for you. However, I've
heard of colisions occuring where the same id was generated multiple times.
