18. Which of the following is the fastest form of RAM and also the most expensive so not used as main memory but rather for cache memory?
[A] SRAM
[B] DRAM
[C] SDRAM
[D] None of These
Show Answer
Correct Answer: A [SRAM]
Notes:
Static random-access memory is a type of memory that uses bistable latching circuitry to store each bit. SRAM is volatile in the conventional sense that data is eventually lost when the memory is not powered.
19. Which of the following consist of the computer main memory?
[A] Hard drive and RAM
[B] CD-ROM and hard drive
[C] RAM and ROM
[D] CMOS and hard drive
Show Answer
Correct Answer: C [RAM and ROM]
