I suggest you check out http://en.wikipedia.org/wiki/UUID. It seems to have a pretty current, but not overwhelming, explanation. Originally the starting point for a UUID was the MAC (hardware) address of the network interface. Theoretically, there should only be one device with any particular MAC address in the whole world. There are exceptions, but they would be mistakes.
For your purposes, you can assume that it is a unique string of 32 hexadecimal digits.
