Storage devices

Question 1

Short term memory of you computer

Answer 1

RAM

Question 2

RAM stands for

Answer 2

Random Access Memory

Question 3

What is the function of RAM

Answer 3

Temporary holds operating system and program files that user is using. this makes it easier for CPU to retrieve specific files working on instead of looking through overcrowded hard drive

Question 4

Can RAM stores data

Answer 4

Cannot store data. Data is lost as soon as computer is turned off

Question 5

What are the form factors of RAM

Answer 5

The two form factors of RAM are DIMM and SO-DIMM

Question 6

What is DIMM stands for

Answer 6

Dual in-line Memory Module

Question 7

What is SO-DIMM stands for

Answer 7

Small outline Dual In-line Memory Module

Question 8

Which RAM form factor is found on desktops and servers

Answer 8

DIMM

Question 9

SO-DIMM is found in which type of computer

Answer 9

SO-DIMM is found in laptops and other small form factor computers

Question 10

Is SO-DIMM and DIMM Ram interchangable

Answer 10

SO-DIMM and DIMM RAM are not interchangable. One will not fit into the slot of the other DIMM slot.

Question 11

DDR stands for

Answer 11

Double Data Rate

Question 12

What is meant by double data rate

Answer 12

means that two transfers of data happen per clock cycle.

Question 13

What is the newest DDR

Answer 13

DDR4

Question 14

the number after the DDR / PC before the hyphen refers to what?

Answer 14

The number after the DDR or the PC represents the generation of the RAM. EX: DDR4 / PC4 = 4th generation

Question 15

A number after the DDR and Hyphen refers to.

EX: DDR-1600 (16,00)

Answer 15

The number that comes after the DDR and Hyphen refers to the mega transfer speed per-sec (MT/s) . EX: DDR-1600 RAM operates at 1,600 Megatransfer speed per-second.

Question 16

What is meant by bandwidth

Answer 16

Bandwidth - refers to volume of data that can be transmitted over a given path in a measured amount of time. bandwidth does not refer to speed. It refers to volume

It is the maximum amount of total data volume (Rate) that can be transfered across a given path at a given amount of time.

Question 17

The “PC” after DDR label means what

Answer 17

The ‘PC” after the DDR stands for the Bandwith per-second.

Question 18

interpret this DDR Label - DDR3-PC3-1,800

Answer 18

Double Data Rate 3rd generation - bandwith of 3rd generation that has a transfer rate of 1,800 megabyte per-seond

Question 19

Bandwith is measured in Megatransfer speed or Megabyte

Answer 19

Bandwith (PC3) is measures in megabyte

Question 20

How Can you overclock RAM

Answer 20

RAM can be overclocked by increasing the bandwith of

Question 21

How can we find-out the total data rate (Bandwidth) of a RAM module

Answer 21

To find-out the total data rate of a RAM module, we multiply the frequency of transfer speed by 8.
EX: 300 * 8 = 2400MB/s

Question 22

Interpret this label: DDR-1,600

Answer 22

Double Data Rate has a transfer speed of 1,600.

Question 23

what is the total data Rate of DDR-1,600

Answer 23

multiply the transfer speed by 8 = 1,600 * 8

Question 24

What is the difference between data rate and transfer speed/frequency

Answer 24

Data Rate is the amount of data that can travel across a given bandwith. It is expressed as PC3-… transfer speed or frequency measures how fast the data can be transfered. It does not have any letters infornt of the number.

Question 25

What is meant by RAM Timing and latency response

Answer 25

RAM timing and latency response measures how fast RAM can respond to request in nanoseconds. The lower the number, the faster the response rate.

Question 26

what is CAS stands for

Answer 26

Column Address Strobe

Question 27

What is CAS latency

Answer 27

CAS Latency is the delay in clock cycles between the READ command and the moment data is available

Question 28

Is a higher CAS latency better than alower Number

Answer 28

The lower CAS means that the delay in clock cycle is less. therefore, the lower number is better

Question 29

Is RAM capacity more important than CAS Latency

Answer 29

Capacity is better than latency since larger RAM capacity will be able to hold more temporary data
