D. ROM

 

2. A chip that allows the BIOS to be upgraded without removing it from the motherboard is a/anA. SDRAM.

B. CMOS.

C. ROM.

D. EEPROM.

 

3. Which of the following statements is true?

A. Memory values tend to be permanent parts of the hard drive.

B. To perform a task, the CPU accesses the necessary information from memory.

C. When you first run a program, it's transferred to the memory in its entirety.

D. "Memory" generally refers to ROM.

 

4. What is a clock rate?

A. The speed at which a hard disk spins

B. Oscillator on the board usually measured in MHz

C. Maximum transfer rate to L2 cache

D. Cursor flashing speed

 

5. How does memory cache speed up computer processing?A. Cache memory does auto-defragmenting, so access time is faster.

B. Cache memory refreshes instantly, so access time is faster.

C. Cache memory doesn't need to be refreshed, so access time is faster.

D. Cache memory uses more buffer space, so access time is faster.

 

6. _______ cache memory is designed inside the CPU.A. L2.

B. 2 GB

C. 4 GB

D. 8 GB

 

8. The cache uses a/an _______ method to anticipate what the CPU will need next.A. best-guess

B. random

C. worst-case

D. algorithmic

 

9. Which of the following analogies best describes the relationship between RAM and its ability to store data?A. Open telephone line

B. Bucket with a hole in it

C. Large bank vault with a complex combination

D. Black box with an input and output

 

10. Which form of RAM technology eliminates the need for time delays by keeping the memory cycles in tune with the system clock?A. EDO RAM

B. SDRAM

C. SRAM

D. BEDO RAM

 

11. EPROM and Flash memory are both types ofA. read-only memory.

B. random access memory.

C. volatile memory.

D. basic input/output systems.

 

12. Two technicians are discussing the interface between system memory and the motherboard. Technician A says data errors caused by speed mismatches are handled by making the memory run a parity check for every bit accessed. Technician B says those speed mismatch errors are avoided by building time delays into the motherboard to allow the system to catch up to the memory. Which technician is correct?

A. Neither

B. Only Technician B

C. Only Technician A

D. Both

B. Nanoseconds

C. Attoseconds

D. Milliseconds

 

15. If you're required to install memory in pairs for the system to work, what type of memory module are you most likely using?A. DIPP

B. DIMM

C. SIPP

D. SIMM

 

16. Two technicians are discussing PROM. Technician A says that PROM chips are expensive and formatted with a device called a memorizer. Technician B says that PROM memory addresses are not arranged in rows and columns. Which technician is correct?

A. Both

B. Only Technician B

C. Only Technician A

D. Neither

 

17. If buying memory for a notebook computer, what type of module should you most likely purchase?A. DIMM

B. RIMM

C. SO-DIMM

D. SIMM

B. The SIMM is soldered to the system board.

C. Every SIMM houses a row of pins on each side.

D. SIMMs are larger and thus hold more memory.
