A Roundtable Discussion on File Management
As the amount of file-based data in your enterprise continues to grow, your organization must find more efficient and cost-effective ways to manage that data. Fortunately, File Area Networks (FANs) have emerged as a new way to simplify file data management. In this interactive roundtable Webcast, you will hear three perspectives on file management.

QuickStudy: Global positioning systems
Like many people, I've come to take for granted the availability of navigation systems in cars and handheld devices based on the Global Positioning System. But it was all abstract until I recently acquired a modern GPS myself. My reaction reminded me of Arthur C. Clarke's Third Law: "Any sufficiently advanced technology is indistinguishable from magic."
The basis for GPS is 29 satellites orbiting the Earth 12,000 miles up; five of them are spares. The U.S. military began launching them in 1978, and it took until 1994 to get 24 in orbit -- enough to calculate a position anywhere in the world. These 2,000- to 4,000-pound satellites are 17 feet wide with their solar panels extended. They traverse six separate orbits, and each orbit has four satellites chasing one another.
The satellites are positioned so that any ground-based GPS receiver can always "see" -- receive data from -- at least four of them. A master control station in Colorado Springs and five unstaffed monitor stations around the world track each satellite's orbit precisely. If they find a satellite out of position, they command its booster rockets to nudge it back on track.
