Denial of Service Attack 1
Denial of Service Attack 1 : (ICT) Abbreviation, DoS attack. An illegal act, with the intent of disabling a server. A server responds to external requests from its network. For example a web server responds to a browser calling for a web page to be delivered from its hard drive. Each request takes a small amount of time and some CPU resources on the server. With a 'Denial of Service' attack, the server is overwhelmed by millions of rogue requests being sent it, effectively using up all its resources and denying normal service for legitimate users
