What is a "DoS" (denial of service) attack?

Hacker X (Computer Security Expert) gives expert video advice on: How can I tell if I've been hacked?; What should I do if I've been hacked? and more...

A denial of service attack or DOS attack is basically when the connection between a larger system and the users who would need access to the system is broken. This will allow somebody to work on or change or modify that larger system where others can't assess it or monitor it. You may have seen this in, like, the FBI site had been hacked with information that had been put up on the pages. And it seems really impossible but if you isolate that site, some people will try to access it are denied access. It gives somebody time to access it.
