What is the purpose of a memory module's heatsink? MCQ with Answer and Explanation

What is the purpose of a memory module's heatsink?
A. To dissipate heat generated by the memory chips
B. To increase memory capacity
C. To improve memory speed
D. To protect against physical damage
Answer: Option A
Solution (By JKSSB Mock Tests)
Heatsinks on RAM modules help dissipate heat, especially on high-performance memory running at higher speeds, to maintain stability.

Question #1
What is the typical transfer rate of a USB 2.0 flash drive?
A. 480 Mbps
B. 10 Gbps
C. 60 MB/s
D. 5 Gbps

Correct Answer: Option A


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.

Question #2
What is the primary storage technology used in SSDs?
A. Optical disks
B. NAND flash memory
C. Magnetic disks
D. DRAM cells

Correct Answer: Option B


Explanation:
SSDs use NAND flash memory, which is non-volatile and based on floating-gate transistors. HDDs use magnetic disks, and optical discs use lasers.

Question #3
Which type of memory uses a constant electrical current loop through cross-coupled inverters to hold its data state without needing refresh cycles?
A. DRAM
B. SRAM
C. Flash Memory
D. EPROM

Correct Answer: Option B


Explanation:
SRAM (Static RAM) uses a latching circuitry design (typically 6 transistors per cell forming cross-coupled inverters) to maintain its state as long as power is applied.
