Question | Answer |
---|---|
Advanced Configuration and Power Interface (ACPI) | Specification developed by Intel, Comapq, Phoenix, Microsoft, and Toshiba to control power on computer and other devices. |
back-side bus (BSB) | The portion of a processor's internal bus that connects the processor to the internal memory cache. The bus operates at a much higher frequency than the front side bus. |
case fan | A fan inside a computer case used to draw air out of or into the case. |
Centrino | A technology used by Intel whereby the processor, chip set, and wireless network adapter are all interconnected as a unit which improves laptop performance. |
chassis air guide (CAG) | A round air duct that helps to pull and direct fresh air from outside a computer case to the cooler and processor. |
Cool’n’Quiet | A feature of AMD processors that lowers power requirements and helps keep a system quiet. |
Cooler | A combination cooling fan and heat sink mounted on the top or side of a processor to keep it cool. |
DRAM | The most common type of system memory, it requires refreshing every few milliseconds. |
dual-core processing | A processor package that contains two core processors, thus supporting four instructions at once. |
Enhanced Intel SpeedStep Technology (EIST) | A processor feature used by Intel that steps down processor frequency when the processor is idle to conserve power and lower that. |
Execute disable bit | A processor security feature by Intel that prevents software from execution r reproducing itself if it appears to be malicious. |
front-side bus (FSB) | The bus between CPU and memory on the motherboard. |
heat sink | A piece of metal, with cooling fins, that can be attached or mounted on an integrated chip to dissipate heat. |
hyper-threading | The Intel technology that allows each logical processor within the processor package to handle an individual thread in parallel with other threads being handled by other processors within the package. |
hyper transport | The AMD technology that allows each logical processor within the processor package to handle an individual thread in parallel wit other threads being hype package. |
internal bus | The bus inside the CPU that is used for communication between the CPU's internal components. |
Level 1 (L1) cache | Memory on the processor die used as a cache to improve processor performance. |
Level 2 (L2) cache | Memory in the processor package, but not on the processor die. The memory is used as a cache or buffer to improve processor performance. |
Level 3 (L3) cache | Cache memory further from the processor core than Level 2 cache, but still in the processor package. |
