DDoS

DDOS stands for "Distributed Denial of Service". It's a kind of attack when someone tries to make a website, server, or network unavailable. They do this by sending a lot of fake traffic or requests to the website, server, or network all at once. This can make it hard for the website, server, or network to respond to real users who are trying to use it.
