here is a video from YouTube that I randomly choose to link here and should give you a little more insight into what and how ddos attacks work and how they require no skill what so ever and is not considered hacking.

CDN is a defense.

But let me tell you, nothing and I mean nothing makes me feel like a hacker than the smooth gui of loic. Smooth as a babies bottom.

The  diference is: A DoS (Denial of Service) is a single machine attack, and DDoS (Distributed Denial of Service) is a multi machine attack that can use botnets. An DoS attack can have multiple purposes, so for a good tutorial google it
