Denial-of-service attack's and 'Hacktivism'

In today's world the internet is now increasingly important, and so are computers. However, the endless lists of benefits from keeping in touch to controlling the right conditions for life can be challenged by the threats of e-safety.

4% percent of all internet traffic is DoS packets. DoS attacks are getting more popular with wannabe hackers so to speak. These attacks are attempts to make a network unavailable for its intended use. Targets and motives of these DoS attacks may vary but the majority of the time they aim to suspend access to the internet or networks.
     DoS'ing requires no knowledge of networking or how anything works (Hence the phrase, monkey with a rocket launcher), as many pieces of software have been made to make this process much more simple. For example:

Low Orbit Ion Cannon

iDisconnect

ServerDeath

 I am not responsible for the use of these tools, DoS'ing is illegal.

A DoS attack is not very effective against large networks. This is where a DDoS attack is more likely to take place. A DDoS is a Distributed-Denial-of-service attack. These are when multiple computers take place in an attack at the same time, in some cases they can transfer up to and over 150GB of data at any one time. The most popular choice to organize a DDoS attack is by convincing a bunch of people to take place in a DoS attack at the same time, an example of this... The infamous Anonymous.
     Anonymous is 'Hacktavist' group who represent freedom and are anti-censorship. They also believe that people have the right to know all the dirty secrets of the higher ups. They aim to take down anyone in their path and humiliate all that goes against their views. Anonymous consist of normal people who take it into their own responsibility to do right. The vigilante that choose to represent Anonymous do it in all kinds of ways from protests and riots to DDoS attacks. Anonymous would convince all of its 'Members' to take part in these things instead of using a botnet,
     A Botnet comes from the words 'Robot' and 'Network' a person would take control of a group of computers and then using them they would DDoS a server/computer.
