7.       Which of the following describes the characteristic features of SRAM ?
(A) Cheap but slow
(B) More consumption of power and much costly
(C) Based on transistor - capacitor combination
(D) Low consumption of power
Answer: D
Static Random Access Memory (SRAM) retains its contents by having a constant
source of power applied. This differs from Dynamic Random Access Memory (DRAM) 
that needs to be regularly refreshed for the memory cells to maintain their state. SRAM 
module consumes less power than a DRAM module. This is because SRAM only 
requires a small steady current while DRAM requires bursts of power every few 
milliseconds to refresh. SRAM is faster and more expensive than DRAM; it is 
typically used for CPU cache while DRAM is used for a computer's main memory.
