Please answer in a proper way, i mean in a nicely described way What are the differences between DOS Attacks, DDOS Attacks and Reflective DDOS Attacks? Which are the most dangerous? And how do you execute each of them? Describe in detail.

Sounds like you want us to finish your term paper or exam question. Maybe you could do the work and let us know what you find out? Thank you.
1) DOS - denial of service - one host attacks another host. eg: one server attacking another server. 2) DDOS - distributed denial of service - many hosts attack one host. eg: a botnet attacking a server. 3) Reflective DDOS - attacker employs IP spoofing techniques against a middle target, that middle target responds (attacks) the spoofed IP (the target). Indirect attack on target - commonly done with recursive nameservers as the middle target (middle target is usually an innocent participant). eg: client requests dns lookup, middle server responds to a 3rd system with this traffic effectively attacking the 3rd system. Hope that helps
