3.2 Given a scenario, install the appropriate RAM

Question 1

Location on hard drive used temporarily for storage when memory space is low. When there is insufficient memory for the task at hand, contents are moved to the drive to free up memory.

Answer 1

Virtual RAM

Question 2

Used in laptops and mobile devices. Smaller sized.

Answer 2

(SODIMM) Small Outline dual inline memory module

Question 3

Twice the data rate of DDR2– Larger chip capacities.Maximum 16 GB per DIMM.No backwards compatibility. Has an advantage over SDRAM with increased throughput and system speed.

Answer 3

Double Date Rate 3 (DDR3)

Question 4

Speed increases over DDR3– Faster frequencies– Maximum 64 GB per DIM. No backwards compatibility

Answer 4

Double Data Rate 4 (DDR4)

Question 5

Faster data transfers between the memory module and motherboard– Maximum of 64 GB per DIMM. The key has moved - No backwards compatibility

Answer 5

Double Data Rate 5 (DDR5) SDRAM

Question 6

Detects errors and corrects on the fly– Not all systems use this. Looks the same as non ECC.

Answer 6

Error correction code (ECC)
RAM

Question 7

Does not take advantage of transfer speed between multiple channels.

Answer 7

Single Channel

Question 8

Takes advantage of transfer speeds and can create 64-bit data channels.

Answer 8

Dual Channel

Question 9

Adds third memory module and reduces memory latency by interleaving or accessing each module with smaller bits of data rather than filling up one module before accessing the next one. Data is spread among modules and triples bandwidth.

Answer 9

Triple Channel

Question 10

This type possesses four channels for moving data. Can be used when all four modules are identical in capacity and speeds.

Answer 10

Quad Channel
