"Denial of Service" is a type of attack against computer systems that makes a server become unresponsive to any user requests. This is most commonly performed by flooding the server with huge amounts of senseless requests so that the server gets busy computing all those requests.
Normally, a denial of service attack does not compromise the server's security.

Anatidaephobia is defined as a pervasive, irrational fear that one is being watched by a duck. The anatidaephobic individual fears that no matter where they are or what they are doing, a duck watches.

Anatidaephobia is derived from the Greek word "anatidae", meaning ducks, geese or swans and "phobos" meaning fear.
