Chapter 6 - Support processors #2

Level 3 (L3) cache A type of internal cache (L3).Level 3 (L3) cache
liquid cooling system A more exotic method to keep a system cool. Options include refrigeration, peltiers, and water coolers.liquid cooling system
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. See also system bus.
MMX (Multimedia Extensions) The first technology to support repetitive looping, whereby the processor receives an instruction and then applies it to a stream of data that follows. Prior to MMX, each data set had to be preceded by an instruction to process it.
multi-core processing With this technology, the processor housing contains two or more 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.multiplier
multiprocessor platform 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.multiprocessor platform
octo Multicore processing using eight cores and supporting sixteen instructions at once.octo
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 gaming.overclocking
PowerNow! AMD's technology to put the processor in a sleep state when they are inactive and reduce voltage requirements and CPU frequency depending on the demands placed on the processor.PowerNow!
processor frequency The speed, or frequency, at which the CPU operates. Usually expressed in GHz.processor frequency
quad core Multicore processing using four cores and supporting eight instructions at once.quad core
S1 state An Advanced Configuration and Power Interface (ACPI) power mode where the hard drive and monitor are turned off and everything else runs normally. Some manufacturers call this mode the sleep mode or standby mode.s1
S2 state An Advanced Configuration and Power Interface (ACPI) power mode where the hard drive, monitor, and processor are turned off. This mode is also called standby or sleep mode.s2
S3 state An Advanced Configuration and Power Interface (ACPI) power mode where everything is shut down except RAM and enough of the system to respond to a wake-up call such as pressing the keyboard or moving the mouse. s3
static RAM (SRAM) RAM chips that retain information without the need for refreshing, as long as the computer's power is on. They are more expensive than traditional DRAM.static RAM
stop errors Errors that occur while Windows Vista/XP is loading. They appear on a blue background and the system halts.stop errors
thermal compound A creamlike compound placed between the bottom of the cooler heatsink and the top of the processor.thermal compound
triple core Multicore processing using three cores and supporting six instructions at once.triple core
