A driver is a program that controls a device such as a printer, mouse, or keyboard. A driver acts like a translator between the device and the programs that use the device. Each device has its own set of specialized commands that only its driver recognizes. [. . . ] To verify that the new chip will correctly run the software written for Intel Architecture processors, a team of Intel engineers is dedicated to compatibility testing. In a state-of-art lab, this group runs an extensive set of operating systems, applications, network tests and stress tests repeatedly to ensure that the processor is compatible with representative software. Just as importantly, we work with hardware and software companies in the computer industry to ensure that our processors are compatible with their products. Additionally, a sampling of Intel processors are subjected to a rigorous "burn-in" test whereby the chip is operated at higher-than-normal temperatures and voltages. [. . . ]
