Platform As A Service, or PaaS is the latest development in virtualization. Where companies started to offer applications online (Saas, Software As A Service) and the use of virtual servers is becoming mainstream, more and more companies now offer a complete operating system as a service online. ………

Research results from University of Maryland physicists show that graphene, a new material that combines aspects of semiconductors and metals, could be a leading candidate to replace silicon in applications ranging from high-speed computer chips to biochemical sensors. The research, funded by the National Science Foundation (NSF) and published online in the journal Nature Nanotechnolgy, [...]

Computers, long used as tools to design and manipulate three-dimensional objects, may soon provide people with a way to sense the texture of those objects or feel how they fit together, thanks to a haptic, or touch-based, interface developed at Carnegie Mellon University. Unlike most other haptic interfaces that rely on motors and mechanical linkages [...]

A team of academic, industry and independent scientists has demonstrated a new class of computer attacks that compromise the contents of secure memory systems, especially in laptops. The attacks overcome a broad set of security measures called disk encryption, which are meant to secure information stored in a computers permanent memory. The scientists cracked several [...]

Pirated microchips — chips stolen from legitimate factories or made from stolen blueprints — account for billions of dollars in annual losses to chipmakers. But a series of novel techniques developed at Rice University over the past year could stop pirates by allowing chip designers to lock and remotely activate chips with a unique ID [...]

Hardware piracy, or making knock-off microchips based on stolen blueprints, is a burgeoning problem in the electronics industry. Computer engineers at the University of Michigan and Rice University have devised a comprehensive way to head off this costly infringement: Each chip would have its own unique lock and key. The patent holder would hold the [...]

As computers become more complex, the demand increases for more connections between computer chips and external circuitry such as a motherboard or wireless card. And as the integrated circuits become more advanced, maximizing their performance requires better connections that operate at higher frequencies with less loss……..
