What is the primary architectural disadvantage of Dynamic RAM (DRAM) compared to Static RAM (SRAM)?
A. DRAM consumes less power overall.
B. DRAM cannot handle multi-threaded processing requests.
C. DRAM is structurally more complex and expensive per gigabyte.
D. DRAM requires periodic electrical refreshing which slows down access speed.
Answer: Option D
Solution (By JKSSB Mock Tests)
DRAM stores data using capacitors, which lose charge over time. This design requires continuous refreshing cycles, introducing latency that makes it slower than SRAM.
Explanation:
The scaling path for binary exponents places $2^{10}$ as KB, $2^{20}$ as MB, $2^{30}$ as GB, $2^{40}$ as TB, $2^{50}$ as PB, and $2^{60}$ bytes as 1 Exabyte (EB).
