-
Ramdom Access Memory
-
Virtual Memory
-
Cache Memory
-
Both (2) and (3)
C
Correct answer
Explanation
Cache memory is installed between CPU and Main memory in memory hierarchy.
-
DRAM
-
SRAM
-
ROM
-
Both (1) and (2)
B
Correct answer
Explanation
SRAM is expensive than DRAM and ROM because it stores information as long the power supply on and it also consumes more power.
