Which of the following is the fastest type of memory?
A. DRAM
B. Flash
C. SRAM
D. ROM
Answer: Option C
Solution (By JKSSB Mock Tests)
SRAM is the fastest among the listed options because it does not need refresh cycles and uses flip-flops, allowing near-instant access times, though it is more expensive.
Explanation:
SSDs have much faster random access times because there is no mechanical latency (seek time, rotational latency). They are also more resistant to shock and quieter.
Explanation:
USB 2.0 has a maximum signaling rate of 480 Mbps (megabits per second), which translates to about 60 MB/s theoretical, but actual is less.
Explanation:
3D NAND technology stacks flash memory cells vertically in multiple layers, allowing manufacturers to achieve massive storage densities on a single silicon die.
