DOS Attacks - Denial of Service Attacks

DOS attack is a term which stands for denial of service attack. Denial of service is a type of computer attack instigated most often by hackers or terrorists who wish to shut down or disrupt Internet services. Denial of service attacks are perpetrated many ways, but the three most common are bandwidth consumption, resource consumption, and network connectivity.
