This technology for transferring data between a computer's hard disk and memory was developed by Quantum and Intel. The maximum burst rate of an Ultra DMA hard drive is 33.3 MBps. The original DMA (Direct Memory Access) protocol could only transfer data at half that speed.Thanks to Ultra DMA, programs can open faster and run more smoothly. This is because Utlra DMA can send more data to the memory in less time than the original DMA. Ultra DMA also has a built-in utility called Cyclical Redundancy Checking (CRC) that helps protect data integrity. So if you want a nice, fast hard drive, look for one that supports Ultra DMA.Copyright 2010 TechTerms.com. Unauthorized duplication is prohibited.
A helicopter was flying around above Seattle when an electrical malfunction disabled all its navigation and communications equipment. With all the clouds and haze, the pilot couldn't determine his position or how to get to the airport. But he saw a tall building, flew toward it, circled, drew a handwritten sign, and held it up. The sign read, "WHERE AM I?" People in the building quickly responded with their own sign: "YOU ARE IN A HELICOPTER." The pilot smiled, waved, looked at his map, plotted the course to the airport and landed safely. On the ground, the co-pilot asked him how their sign helped determine the helicopter's position. "I knew that had to be the Microsoft building," the pilot said, "because they gave me a technically correct, but completely useless answer."
