Describe a situation in which absolute denial of a service to a user ( that is, the user gets no response from the computer) is a serious problem to that user. Describe another example where 10 percent denial of service ( that is, the user's computation progresses, but at a rate 10% slower than usual) is a serious problem to that user. Could access by unauthorized people to a computing system result in a ten percent denial of service to the legitimate users? If so, how?
