A new form of computer memory has won an award for innovation. UltraRAM combines the performance of ordinary computer memory with the long-term storage of flash. Most memory in a computer is DRAM (dynamic random access memory). This holds data that ... the computer processor is most likely to need to access imminently. It's a little like having paper documents on a desktop rather than in a filing cabinet: the cabinet has much more room, but it takes some time to walk to the cabinet to get the information, versus having it right on the desktop. One of the key drawbacks of DRAM is that it stores ... (view more)

Researchers say they used a single five-mile cable to transmit twice the amount of data that's currently used by the entire Internet. While it could one day mean faster connections for users, the main benefit of the research could be more ... energy-efficient data centers. The project involved the Technical University of Denmark and the Chalmers University of Technology in Gothenburg. They explored the way most high-speed data connections today involve encoding signals to transmit as light. The key was combining a single laser with a specially-designed optical chip. This breaks the light into 223 ... (view more)

A company that helps protect websites against a popular form of cyber attacks says it's solved a major security concern. The change could mean high-profile websites can be much more resilient and secure. The company in question is CloudFlare, which ... offers services to defend against denial of service attacks (DoS) , including distributed denial of services attacks (DDoS) . That's where cyber attackers flood a website with bogus data requests, until the site (or server) is no longer able to deal with legitimate requests. Oftentimes such an attack will bring a web server to a grinding ... (view more)
