Detailed explanation-1: -A Denial-of-Service (DoS) attack is an attack meant to shut down a machine or network, making it inaccessible to its intended users. DoS attacks accomplish this by flooding the target with traffic, or sending it information that triggers a crash.
Detailed explanation-2: -DoS attacks typically work by flooding a targeted machine with requests until regular traffic cannot be processed, causing denial-of-service to additional users. A DoS attack is characterized by using a single computer to launch the attack.
Detailed explanation-3: -Which of the following is true of a DDoS attack? Attack traffic comes from lots of different hosts; The “Distributed” in DDoS means that the attack traffic is distributed across a large number of hosts, resulting in the attack coming from many different machines.

Examples of targets might include email, online banking, websites, or any other service relying on a targeted network or computer.
