what is DDOS attack

DDOS Attack Diagram source: wikipedia
Currently the level of security is being increased though how far they are increased the hacking is getting twice much each day and after.

Umm i have first heard that demonoid is attacked DDOS attacked which was my favourite site for accessing files and download. Then after that i stared to explore regarding those things. Recently ago same case was happened to godaddy as well. Though they have recovered from it but demonoid still is not in existance.

hi lets go and talk about the DDOS attack, its defined as Distributed Denial of services where a server is targeted and attacked later. So what happens here is let me go through in points.
1. Firstly the hackers targets the server computer and makes a program which will collect the hundreds of clients computer and make a sunchronous communication. Those clients computer could be yours and mine. as when we take some those files out computer will also be affected and they will be working for the hackers. may be the any of the best antivirus wont be knowing those things.
2. Now our computer are in their controls and those computer will be corresponding as they want.
3. There are others hundreds and thousands of computers follows those instructions and gives hundreds and thousands of instructions and play with servers. which will give unwanted load to the server that they wont be working and this those servers fails to work.

This is how the ddos attack are done. thank  you.
