Byline: Brandon Butler and John Gallant Rackspace ended months of speculation in August by announcing it had been acquired by a private equity firm. With a new corporate structure, the [...]

Byline: Michael Cooney and John Gallant Analytics, collaboration and security key to addressing hyper-distributed data centers and networks, Cisco CEO Chuck Robbins says. To access, purchase, authenticate, or subscribe to [...]

Byline: John Gallant, Eric Knorr Few enterprise IT transformations can match the importance of today's long migration from on-premises, client-server computing to cloud computing. This week at Oracle's mammoth OpenWorld [...]

Byline: Brandon Butler and John Gallant IBM Senior Vice President of Cloud Robert LeBlanc says the cloud computing industry is moving beyond a first wave and into a second phase [...]

Risking the wrath of the gods, here's an obvious observation: Networking is everywhere these days. Network technology, in all its rapidly mutating forms, has pervaded every aspect of our personal […]

THE INDUSTRIAL MARKET FOR VIDEO IMAGING APPLICATIONS IS WIDE AND VARIED. IT ISN'T SURPRISING THAT VIDEO CAMERAS FOR INDUSTRIAL APPLICATIONS OFFER A VARIETY OF CHOICES. CCD cameras and frame grabbers [...]

Smart cards are finally establishing a beachhead in the United States. Since their debut in the early '80s, they've found fairly widespread use in Europe but almost none in North [...]

The wide price range and versatility of CCDs make them well-suited for many applications. Industrial and commercial uses for CCDs have flourished in the '90s. Since 1990, charge-coupled devices (CCDs) [...]

Until recently, teleconferencing required two phone lines - one for voice and one for data. However, you can now transmit voice and data over a single POTS (plain-old telephone service) [...]

High-performance PLDs come in a variety of flavors. To choose the right one, consider the speed and time-to-market requirements of your application and learn what each PLD architecture offers. Designing [...]

The ever-shrinking geometries of deep-submicron ASICs can cause interconnect delays, nonlinearities, and physics to dominate a design. Success in designing these devices means designers must work closely with ASIC vendors [...]

Overlaying video and graphics on a VGA monitor requires abundant bandwidth and horsepower. Fortunately, a number of video-connection schemes, high-bandwidth buses, and high-integration chips can transform postage-stamp-sized video overlays to [...]

Historically, designers have viewed PLDs as prototypes and used gate arrays for more cost-effective high-volume applications. Today's designers, however, must weigh factors such as time to market and off-the-shelf delivery. [...]

The PCI bus is filling the need for a high-performance local bus to accommodate the increasing bandwidths of new designs. Now, many vendors are offering bridge chips to help PCI [...]

HIGH-SPEED PERIPHERALS MUST GET ON A HIGH-SPEED HIGHWAY TO MAKE USE OF ALL THEIR CAPABILITIES. THE PCI BUS IS ONE SUCH HIGHWAY, BUT ON-RAMPS IN THE FORM OF OFF-THE-SHELF, GENERAL-PURPOSE [...]

Mobile data communications has become a hotly debated issue. Interest surrounding paging, circuit-switched, and packet-switched networks has lit the fire for the debate, and the announcement of the CDPD network [...]

It seems like everyone is demanding low-power consumption from their ICs these days. The reasons are manifold. Battery-operated devices, such as laptop and palm-top computers and personal digital assistants, require [...]

It was just 1991 when the Consultive Committee for International Telephone and Telegraph (CCITT) ratified Recommendation V.32bis for full-duplex modem-to-modem communications - at the blazing speed of 14.4 kbps over [...]

In the early 1980s, slow CPUs were the limiting factor to system processing; peripherals and memory interfaces were faster. But since the mid-1980s, all that has flip-flopped: Now, the bottleneck [...]

If speech is the mirror of the soul, then many of today's commercial products will reap their just rewards. Maturation of speech-compression coding algorithms is allowing almost every new device [...]

Front-end products for handheld wireless receivers include amplifiers, spdt switches, antennas, attenuators, and filters. Unfortunately, most of these devices come as separate components, which the system manufacturer must wire together. [...]

Every time you think that ||micro~Processors~ have reached their performance limits, some smart-aleck vendor invents a new twist to extend their performance. The latest RISC ||micro~Processors~ have features that earlier [...]

Mixed-signal, mixed-mode, and combination technology. All of these terms have the same meaning--a circuit that mixes analog and digital functions onto a single chip. These complete systems on a chip [...]

Europe has emerged as the world leader in defining digital wireless telecommunications standards. The US lags behind Europe, as does Japan. Now IC vendors worldwide have to decide whether to [...]

Keeping up with modern μPs is like keepinkg up with Speedy Gonzalez--it's hard to do. Nevertheless, vendors of clock-driver chips are up to the task. 'Faster! faster!' marketing screams, 'Our [...]

Designers of first-generation portable computers quickly recognized the need for conserving as much energy as possible from batteries. Because normal operating conditions create battery discharge times of less than 1 [...]

Using RF or infrared broadcasting, digital wireless networks create a dynamic work space with signals that can pass through or bounce off the wall. These networks permit networking in areas [...]

The Global Positioning System (GPS) is a radio-navigation system that employs RF transmitters in 24 satellites. GPS receivers decode the satellites' signals to calculate the latitude, longitude, and altitude of [...]
