100
CAS Latency
What is a method of measuring access timing to memory, which is the number of clock cycles required to write or read a column of data off a memory module.
100
Direct Rambus DRAM and Direct RDRAM and Rambus and RDRAM
What is A memory technology by Rambus and Intel that uses a narrow network-type system bus. Memory is stored on a RIMM module. Also called RDRAM, Rambus, or Direct RDRAM.
100
The most common type of system memory, it requires refreshing every few milliseconds.
What is dynamic RAM (DRAM)
100
Memory on the processor die used as a cache to improve processor performance.
What is Level 1 cache (L1 cache)
100
multiplier
What is The factor by which the bus speed or frequency is multiplied to get the CPU clock speed.
200
Centrino
What is a technology used by intel whereby the processor, chipset, and wireless network adapter are all interconnected as a unit, which improves laptop performance.
200
double-sided
What is A DIMM feature whereby memory chips are installed on both sides of a DIMM.
200
A chipset feature on a motherboard that checks the integrity of data stored on DIMMs or RIMMs and can correct single-bit errors in a byte. More advanced ECC schemas can detect, but not correct, double-bit errors in a byte.
What is ECC (error-correcting code)
200
Memory in the processor package but not on the processor die. The memory is used as a cache or buffer to improve processor performance. Also see Level 1 (L1) cache.
What is Level 2 cache (L2 cache)
200
multiprocessing
What is Two processing units installed within a single processor and first used by the Pentium processor.
300
C-RIMM (Continuity RIMM)
What is A placeholder module that fills a memory slot on the motherboard when the slot does not hold a RIMM in order to maintain continuity.
300
dual channels
What is A motherboard feature that improves memory performance by providing two 64-bit channels between memory and the chipset. DDR, DDR2, and DDR3 DIMMs can use dual channels.
300
A processor that manipulates graphic data to form the images on a monitor screen. A GPU can be embedded on a video card or on the motherboard or integrated within the processor.
What is graphics processing unit (GPU)
300
Cache memory further from the processor core than Level 2 cache, but still in the processor package.
What is Level 3 cache (L3 cache)
300
multiprocessor platform
What is 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 multiprocessor environment.
400
DDR and Double Data Rate SDRAM (DDR SDRAM) and SDRAM II
What is A type of memory technology used on DIMMs that runs at twice the speed of the system clock. Also called DDR SDRAM, SDRAM II, and DDR.
400
dual processors
What is Two processor sockets on a server motherboard.
400
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.
What is Hyper-Threading
400
The memory a processor addresses at one time. Today’s desktop and notebook processors use a memory bank that is 64 bits wide.
What is memory bank
400
parity
What is An error-checking scheme in which a ninth, or “parity,” bit is added. The value of the parity bit is set to either 0 or 1 to provide an even number of ones for even parity and an odd number of ones for odd parity.
500
DIMM (dual inline memory module)
What is A miniature circuit board installed on a motherboard to hold memory. DIMMs can hold up to 16 GB of RAM on a single module.
500
dual ranked
What is Double-sided DIMMs that provide two 64-bit banks. The memory controller accesses first one bank and then the other. Dual-ranked DIMMs do not perform as well as single-ranked DIMMs.
500
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.
What is HyperTransport
500
A processor technology whereby the processor housing contains two or more processor cores that operate at the same frequency but independently of each other.
What is multi-core processing
500
parity error
What is An error that occurs when the number of 1s in the byte is not in agreement with the expected number.
