Answer 12

The memory chips are installed on both sides of the DIMM module

Question 13

what does dual channels mean

Answer 13

The memory controller can communicate with two DIMMS at the same time

Question 14

What does dual ranked mean

Answer 14

Where the chips are grouped on both sides of the DIMM so that the memory controller addresses one group and then address the other

Question 15

What does multicore processing mean

Answer 15

When multiple processors are installed in the same processor housing

What does multiplier mean

Answer 16

The multiplier is the factor that is used to multiply the FSB speed

Answer 20

an older type of memory module

Question 21

What does SIMM mean

Answer 21

Very old type of memory module that is unlikely to ever be seen in any working computer

Question 22

What does SIMM stand for

Answer 22

Single inline memory module

Question 23

What does SO-DIMM mean

Answer 23

Small outline DIMM that are smaller than a regular DIMM

Question 24

What does SO-DIMM stand for

Answer 24

small outline single inline memory module

Question 25

What does static RAM mean

Answer 25

The memory that is used inside a memory cache

Question 26

What does SRAM stand for

Answer 26

static random access memory

Question 27

What does synchronous DRAM mean

Answer 27

A DIMM that runs synchronized with the system clock

Question 28

What does memory bank mean

Answer 28

The memory a processor addresses at one time

Question 29

What is a thermal compound

Answer 29

A compound used to eliminate air pockets, helping to draw heat off of the processor. It transmits heat better than air and makes an airtight connection between the fan and the processor.

Question 30

What is a thread

Answer 30

When windows hands off a task to the CPU it is called a thread and might involve several instructions

Question 31

What is a x86 processor

Answer 31

Older processors that use a 32 bit system

Question 32

What is a x86-64 bit processor

Answer 32

Hybrid processors that can handle a 32 or 64 bit OS

Question 33

What does parity mean

Answer 33

older SIMMS error checking technology

Question 34

What does parity error mean

Answer 34

If the number of bits is not an odd number for odd parity, or an even number for even parity then a parity error occurs

What does RAS Latency mean

Answer 36

A way of measuring access timing

Answer 37

The memory controller can only access one DIMM at a time

Question 38

What does single sided mean

Answer 38

Means that the memory chips are installed on one side of the DIMM module

Question 39

What is triple channels

Answer 39

The memory controller can access three DIMMS at the same time
