1. Which of the following is the name for running the processor or memory at speeds faster than what is recommended?

CPU tweaking

Overclocking

Memory leak

CPU duplicating

Overclocking is the process in which you can set the speeds of the CPU or memory to run at a faster rate than normal. It can lead to overheating and system crashes.

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

CheckIT

AMIDiag

RAMExam

All of these options are correct

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

Explanation

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

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

Keep the surfaces of the modules clean. You can use compressed air or a data-rated vacuum cleaner to remove dust.

Install additional case fans over or behind the location of memory modules to pull hot air out of the system.

All these options are correct

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

Explanation

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

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

ECC memory

Unbuffered memory

Static memory

Desktop memory

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

Explanation

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

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

Hard disk drive

USB flash drive

RAM

ROM

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.

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

Line up the module connectors with the socket

Verify that the locking tabs on the socket are swiveled to the outside (open) position

None of these options is correct

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.

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

Parity-Checking

System checking

ECC (error-correcting code)

Smart checking

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

Explanation

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

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

SDRAM

SRAM

DRAM

DDR

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

Explanation

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

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

Unbuffered memory

No memory

SIMM Module

Stable memory

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

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.

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

DDR

SDRAM

DDR2

Rambus

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

Explanation

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

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

Tin

Copper

Zinc

Gold

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.

Explanation

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

DDR2

SDRAM

SRAM

Rambus

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

Explanation

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

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

DDR3 has the same pinouts as DDR2

DDR3 and DDR2 both use 240-pin connectors

DDR3 uses higher voltages than DDR2

All these options are correct

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.
