Another Example of DoS is thus:
LAX (Los Angeles International Airport) being closed down because security
mistook some lighters that as firearms because they looked like guns.
Imagine the amount of money lost, time wasted, and people irritated when
the Management of LAX closed it down denying service to over 1200 people.
At least 29 flights were canceled or turned away.

On the good note, alot of people who worked at LAX still got paid for time
they didn't have to work :)

It means that there is a service that you, the user, want to use, and
I, the bad guy, am denying it to you.
I could be doing this by standing between you and your keyboard [with a
menacing leer].
I could be doing this by flooding your network with "bad" packets
which, nevertheless, your host would feel honour-bound to spend 100%
of its cycles picking up and replying to.
I could be doing this by burying a fire axe in your favourite disk
drive.
Lots of options.
