Etymology

DoS in computing comes from Denial of Service, where denial means 'refusal' and service means 'a website or online help'. A helpful image is a crowd blocking a shop door so real customers cannot get in, which explains why a DoS attack makes an online service unavailable by flooding it with traffic.
