Distributed Denial of Service

Refers to DoS (Denial of Service) - an acronym for the disruption that 
results from an attack on a network. Hackers execute a DoS with the intent 
of blocking individuals' ability to access Web sites or e-mail. The most 
common form of DoS results from an attacker who sends so many messages to a 
Web site that it can't respond to regular users or it shuts down completely 
(see: broadcast storm). DoS is a criminal act, even if done as a prank; 
major attacks are aggressively investigated by the U.S. Department of Justice.

DDoS stands for "Distributed Denial of Service," an attack in which a 
multitude of compromised systems attack a single target, thereby causing a 
DoS for users of the targeted system. The flood of incoming messages to the 
target system essentially forces it to shut down, thereby denying service 
to legitimate users.
