2. Which of the following are utilities that are used to check memory? (Choose all that apply.)

Explanation

CheckIT, AMIDiag, and RAMExam can all be used to test memory.

Submit
3. To prevent overheating memory modules, which of the following tasks should you perform? (Choose all that apply.)

Explanation

All of these can be done to help prevent any memory issues, such as overheating.

Submit
4. Critical applications and network servers have a special type of memory. What is it called?

Explanation

ECC memory enables the system to correct single-bit errors and notify you of larger errors.

Submit
5. Which of the following loses its contents when you shut down the computer?

Explanation

Random access memory (RAM) loses its contents when the computer shuts down. Hard disk drives, USB flash drives, and read-only memory (ROM) are designed to retain their contents even if they are not receiving power.

Submit
6. To correctly install a DIMM or Rambus module, what should you do? (Choose all that apply.)

Explanation

To correctly insert the memory modules, you should follow all the steps listed. You might also have to use a fair amount of pressure to securely lock these modules in place.

Submit
7. Name the two methods that are used to protect the reliability of memory.

Explanation

These two methods have an additional memory chip added for parity.

Submit
8. Which type of memory chip is much bulkier and more expensive than DRAM?

Explanation

SRAM or Static RAM is bulkier and more expensive than DRAM because it does not require electricity as often as DRAM.

Submit
9. Most types of desktop memory modules use which kind of memory?

Explanation

Unbuffered memory is used in most desktop computers sold in the market. This kind of memory is also used in some servers and workstations.

Submit
10. What type of RAM must be installed in pairs?

Explanation

Rambus memory that uses 32-bit RIMMs must use pairs, and unused sockets must be occupied by a continuity module.

Submit
11. Which of the following are types of metal used for contacts on SIMMs? (Choose two.)

Explanation

The two types of metal that are used as contacts on SIMMs are gold and tin. Placing gold connectors in a tin socket and vice versa are most likely to see corrosion and eventual system lockups.

Submit
12. Which type of memory was the first to run in sync with the memory bus?

Explanation

SDRAM was the first memory type that was in sync with the motherboard’s memory bus.

Submit
13. Which of the following statements are correct about DDR3 memory? (Choose all that apply.)

Explanation

DDR3 and DDR2 both use 240-pin connectors is the only correct answer. While DDR3 and DDR2 both use 240-pin connectors, the connectors use different pinouts and are keyed differently to avoid installing DDR3 in a DDR2 slot or vice-versa. DDR3 uses lower voltage than DDR2. DDR3 memory uses 1.5V DC power, compared to 1.8V DC for DDR2.
