What is RAM parity? |
RAM parity is when memory stores an extra bit (know as a parity bit) used for error detection. Might be required when data integrity is needed. |
|
|
What is ECC Versus Non–ECC |
Error Correnction Code (ECC) in RAM detecs and corrects errors. |
|
|
What is single–sided RAm and What is double–sided? |
1. Single sided is when memory module has a single "bank" of chips/2. Double–sided have chips divided into two sides known as "banks" |
|
|
Steps to install RAM |
1. Select correct memory module2. Employ ESD prevention methods.3. Ready the motherboard4. Install RAM5. Test Installation |

What is SRAM and how is it used? |
SRAM is RAM that doesn't need to be automatically refreshed.It is used as cache memory, as buffers on motherboards or within hard drives, or as temporary storage area for LCD screens. |
|

Dynamic Random Access Memory |
|
|
1. Where is L2 cache located?2. T/F L2 is slower than L1 cache and DRAM3. T/F L2 cache feeds L1 cache |
1. Usually built on to the CPU2. F, it is slower than L1 Cache but faster than DRAM3. T |
|
|
1. T/F L3 cache has the most amount of latency?2. Where is L3 cache usually found? |
1. T, it is the slowest cache but still faster than DRAM2. Can be found on CPU or on board, but usually on CPU |
|
|
1. Where is L1 Cache located?2. T/F L1 is it the fastest cache? |
1. Built into the CPU2. True |
|
|
What is cache? |
Special high–speed memory that reduces the time the CPU takes to access data. |
|
|
What are registers? |
Temporary storage areas |
|

1. 4GB2. 256 TB |
|
|
What does SODIMM stand for? |
Small outline dual in–line memory |
|
|
