DS Chapter 6 Stack 1

TermDefinition
Advanced Configuration and Power Interface (ACPI) Controls power on computers and other devices.
back-side bus (BSB) internal bus that connects the processor to the internal memory cache.
case fan a fan inside a computer case used to draw air out of or into the case.
Centrino intel processor, chipset, and wireless network adapter are all interconnected as a unit, which improves laptop performance.
chassis air guide (CAG) a round duct that helps to pull and direct fresh air from outside the case to the cooler and processor.
Cool’n’Quiet lowers power requirements and help keeps a system quiet.
Cooler sits on top of the processor and consist of a fan.
DRAM The most common type of system memory,D it requires refreshing every few milliseconds.
dual-core processing A processor package that contains two core processors,dual thus supporting four instructions at once.
Enhanced Intel SpeedStep Technology (EIST) steps down processor frequency when the processor is idle to conserve power and lower heat.EIST
Execute disable bit by Intel, is a security feature that prevents software from executing or reproducing itself if it appears to be EDB malicious.
front-side bus (FSB) The bus between the CPU and memory on the motherboard. The bus frequency in documentation is called the system speed, such as 400 MHz. Also called the memory bus, front-side bus, local bus, or host bus.
heat sink A piece of metal, with cooling fins, that can be attached to or mounted on an integrated chip (such as the CPU) to dissipate heat.
hyper-threading The Intel technology th.
hyper transport The AMD technology tr.
internal bus The bus inside the CPU that is used for communication between internal the CPU's internal components
Level 1 (L1) cache Memory on the L1 processor die.
Level 2 (L2) cache Memory in the L2 processor package, but not on the processor die.
Level 3 (L3) cache Some processors use a third cache farther from the processor core, but still in the processor package.
liquid cooling system A method to cool overclocked processors that uses a small pump inside the computer case and tubes that move water or other liquid around components and then away from them to a place where fans can cool the liquid.
memory cache RAM that holds memory data and instructions that the memory controller anticipates the processor will need next.
MMX (Multimedia Extensions) the first multi technology to support repetitive looping.
multi-core processing the processor multi housing contains two or more processing cores that operate at the same frequency, but independently of each other.
multiplier The factor by which the bus speed or frequency is multiplied to get the CPU clock speed.
multiprocessor A system that contains more than one processor. The motherboard has more than one processor socket and the processors must be rated to work in this multi-processor environment.
octo A processor package that contains eight cores and supports 16 instructions at once.
overclocking Running a processor at a higher frequency than is recommended by the manufacturer, which can result in an unstable system, but is a popular thing to do when a computer is used for over gaming.
PowerNow! increases performance and lowers power requirements.
processor frequency The frequency at which the CPU operates. Usually expressed in GHz.
quad core A processor package that contains four cores and supports eight instructions at once.
S1 state the hard drive and S1 monitor are turned off and everything else runs normally.
S2 state the hard drive, monitor, s2and processor are turned off.
S3 state everythings3 is shut down except for RAM.
static RAM (SRAM) SRAM chips that retain information without the need for refreshing, as long as the computers power is on.
stop errors An error at the kernel level that is severe enough to cause the operating system to stop all processes.
thermal compound placed thermal between the bottom of the cooler heat sink and the top of the processor.
triple core A processor package that contains three core processors, thus supporting six instructions at once.
