Denial of Service, DoS, attack can come in many shapes and forms. The Blue Screen of Death from Windows can be one if it is caused by someone and not just poor programming. Also, the infamous DDoS attacks from earlier this year are an example where multiple 'zombie' computers coordinate together to attack a host all at the same time. A DoS attack is anything that maliciously prevents the computer from doing what was intended. This is usually accomplished by errors in code that will cause the program to eat up all the system resources.

Preventing DoS attacks is like preventing buffer overflows, but a firewall will also help with this, unlike buffer overflows.
