DoS stands for?

• A. Denial of Service
• B. Denial of Service Attack
• C. Service Denial
• D. Distributed Denial

Answer: (A)

DoS stands for Denial of Service—a type of attack aimed at making a network service unavailable by flooding it with traffic or exhausting its resources so legitimate users can’t access it. The standard expansion used in exams is Denial of Service. Some people colloquially say "Denial of Service Attack," but the official acronym is built from Denial of Service. The other options don’t fit because they scramble the wording or point to a related but distinct concept: “Service Denial” switches the order of the words, and “Distributed Denial” is incomplete and resembles the term used for distributed denial of service (DDoS), which involves multiple sources.
