Short for Distributed Denial of Service, DDoS is a DoS attack that uses several computers to attack one victim. Often, a DDoS attack is started by hacking dozens, hundreds, or even thousands of other computers, the uploading instructions on when to attack and how. A DDoS is used against a big site capable of handling large amounts of traffic.
You can use services like Cloudflare to help protect your website from DDoS attacks.
