What is the main difference between SRAM and DRAM?
A. SRAM needs refreshing; DRAM does not
B. SRAM is non-volatile; DRAM is volatile
C. SRAM is slower than DRAM
D. SRAM uses flip-flops; DRAM uses capacitors
Answer: Option D
Solution (By JKSSB Mock Tests)
SRAM uses flip-flop circuits to store each bit, while DRAM uses a capacitor and a transistor. SRAM is faster and does not need refreshing, but is more expensive. Both are volatile.
Explanation:
Bits and bytes with SI prefixes (kilo, mega, giga) are all valid units. However, in computing, binary multiples are more common for memory capacities.
