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 uses flip-flops; DRAM uses capacitors
D. SRAM is slower than DRAM
Answer: Option C
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:
A cylinder consists of the exact same track number intercepted vertically across all available platter surfaces in a hard disk drive assembly.
Explanation:
Average rotational latency is half of the rotation period. For 7200 RPM, the disk rotates once every 8.33 ms, so average latency is 4.17 ms (approximately).
