| Question | Answer |
|---|---|
| Level 1 Cache | Memory on the processor die. |
| Level 2 Cache | Memory in the processor package. |
| Level 3 Cache | Cache memory further from the processor core than level 2, butt still in the processor package. |
| 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 with other threads being handled by other processors within the package. |
| Front-Side Bus (FSB) | The bus between the CPU and memory on the motherboard. |
| Internal Bus | The bus inside the CPU that is used for communication between the CPU's internal components. |
| Back-Side Bus (BSB) | The portion of a processor's internal bus that connects the processor to the internal memory cache. |
| Processor Frequency | The frequency at which the CPU operates. |
| Multiplier | The factor by which the bus speed is multiplied to get the CPU clock speed. |
| Overclocking | Running a processor at a higher frequency than is recommended. |
| Multiprocessor Platform | A system that contains more than one processor. |
| Multi-Core Processing | A processor technology whereby the processor housing contains two or more processor cores that operate at the same frequency. |
| Dual Core | A processor package that contains two core processors. |
| Triple Core | A processor package that contains three core processors, thus supporting six instructions at once. |
| Quad Core | A processor package that contains four cores and supports eight instructions at once. |
| Octo Core | A processor package that contains eight cores and supports 16 instructions at once. |
| Memory cache | A small amount of faster RAM that stores recently retrieved data, in anticipation of what the CPU will request next, thus speeding up access. |
| dynamic RAM | The most common type of system memory. |
| Static RAM | RAM chips that retain information without the need for refreshing, as long as the computer's power is on. |
| PowerNow! | An AMD technology that increases performance and lowers power requirements for processors. |
| MMX | The first technology to support repetitive looping. |
| Cool'n'Quiet | A feature of AMD processors that lower power requirements and helps keep a system quiet. |
| EIST | A processor feature used by Intel that steps down processor frequency when the processor is idle to conserve power and lower heat. |
| Execute Disable Bit | A processor security feature by Intel that prevents software from executing or reproducing itself if it appears to be malicious. |
| 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. |
| Cooler | A combination cooling fan and heat sink mounted on the top or side of a processor to keep it cool. |
| Heat Sink | A piece of metal, with cooling fins, that can be attached to or mounted on an integrated chip to dissipate heat. |
| Thermal Compound | A creamlike substance used to eliminate air pockets and to help to draw heat off the processor. |
| Case Fan | A fan inside a computer case used to draw air out of or into a case. |
| Liquid Cooling System | A method to cool overclocking processors. |
| ACPI | |
| S1 State | The ACPI power saving mode where the hard drive and monitor are turned off and everything else runs normally. |
| S2 State | The ACPI power saving mode where the hard drive, monitor, and processor are turned off. |
| S3 State | The ACPI power saving mode where everything is shut down except RAM. |
| S4 State | The ACPI power saving mode where everything in RAM is copied to a file on the hard drive and the system is shut down. |
| Chassis Air Guide | A round air duct that helps to pull and direct fresh air from outside a computer case to the cooler and processor. |
