Windows end-users and Internet routing technology have both become more frequent targets of intruder activity. The control mechanisms for DDoS attack networks are changing to make greater use of Internet Relay Chat (IRC) technology. The impacts of DoS attacks are causing greater collateral damage‚ and widespread automated propagation itself has become a vehicle for causing denial of service. While DoS

Research Question: How the amount of vitamin C in fruit juices affects its freshness and till what extent is the information provided on the pack by manufacturers is reliable? Background Information: Hypothesis: -fresh juices have more vitamin C than long-life -juice that is ‘not from concentrate’ is best in terms of vitamin content -if heat destroys vitamin C then heat-treated long-life juices will have lower concentrations -if heat destroys vitamin C then boiled fruit juice will have lower
