DDOS = Distributed Denial Of Service, a technique for attacking a server with the intention to shut it down by the overload of requests.

UUID = Unique Universal IDentifier, which are used to identify each individual player since name changes were made possible in Minecraft. They are used everywhere in the game data and on servers to let the game recognise the player even after a name change. You can find out your own UUID with various online tools, such as this one.
