    Companies and individuals are using an increasing number of computers, peripherals, mobile devices, consumer electronics, and other machines in their offices or houses. For convenience, many users want to network these devices. Bluetooth radio-based, short-range, wireless-networking technology has received considerable attention as a means for accomplishing this. However, ultrawideband, a 30-year ... View full abstract»

    Hard-drive technology is at a critical point in its history. Vendors are hitting limits on the amount of data that current technology can read and write on a square inch of disk space. While hard drive capacity will continue to increase, the rate of areal-density growth will likely slow. This will hurt companies such as Maxtor, that make much of their revenue by selling new and bigger hard drives ... View full abstract»

    Computational and laboratory experiments generate masses of data that must be stored reliably, with minimal effort on each researcher's part, and must be retrievable for decades. The storage environment must also work seamlessly across scientific disciplines and capture all of a file system's features in a semantically-based catalog that provides Boolean, keyword, and tree-based data access. The a... View full abstract»

    Servers: high-end, multiprocessor systems running commercial workloads, have typically included extensive cooling systems and resided in custom-built rooms for high-power delivery. Recently, as transistor density and demand for computing resources have rapidly increased, even these high-end systems face energy-use constraints. Commercial-server energy management now focuses on conserving power in ... View full abstract»

    By using adaptive processing to dynamically tune major microprocessor resources, developers can achieve greater energy efficiency with reasonable hardware and software overhead while avoiding undue performance loss. Adaptive processors require few additional transistors. Further, because adaptation occurs only in response to infrequent trigger events, the decision logic can be placed into a low-le...

    Although effective techniques exist for tackling disk power for laptops and workstations, applying them in a server environment presents a considerable challenge, especially under stringent performance requirements. Using a dynamic rotations per minute approach to speed control in server disk arrays can provide significant savings in I/O system power consumption without lessening performance.

    Off-state leakage is static power, current that leaks through transistors even when they are turned off. The other source of power dissipation in today's microprocessors, dynamic power, arises from the repeated capacitance charge and discharge on the output of the hundreds of millions of gates in today's chips. Until recently, only dynamic power has been a significant source of power consumption, ... View full abstract»

    Advances in battery technology have not kept pace with rapidly growing energy demands. Most laptops, handheld PCs, and cell phones use batteries that take anywhere from 1.5 to 4 hours to fully charge but can run on this charge for only a few hours. The battery has thus become a key control parameter in the energy management of portables. To meet the stringent power budget of these devices, researc... View full abstract»

    In the area of digital commerce and the Internet, the article looks at security as a risk management proposition. The core theme of risk management is to forego perfection and instead make tradeoffs (potentially messy), in pursuit of goal states. Security is not an end but a means, not a product but a process. The question is only what tradeoffs to make. View full abstract»

    The origin of the University of Florida's Digital Arts and Sciences (DAS) curriculum is steeped in myth and adventure. Through DAS, CISE seeks to produce the next-generation computer scientist. To justify this statement, we need look no further than recent computing history and how this trend in fast hardware and immersive environments will transform foundational computer science in areas such as ...

    The term digital divide usually refers to the great disparities between and within societies in the use of digital technology. In December 2003, the United Nations held a World Summit on the Information Society to adopt a declaration that embodies, in its draft form at least, "the ambitious vision" of "bridging the digital divide." The declaration's hopes focus on the rapid pace of development of ... View full abstract»
