Describe an example in which absolute denial of 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 to a user (that is, the user's computation progresses but at a rate 10 percent slower than normal) is a serious problem to that user. Could access by unauthorized people to a
computing system result in a 10 percent denial of service to the legitimate users? How?

Ten
percent
degradation:
