Which of the following is not a valid storage capacity for a standard pen drive? MCQ with Answer and Explanation

Which of the following is not a valid storage capacity for a standard pen drive?
A. 120 GB
B. 16 GB
C. 32 GB
D. 8 GB
Answer: Option A
Solution (By JKSSB Mock Tests)
While pen drives come in various capacities, common sizes are powers of 2 (8, 16, 32, 64, 128, 256 GB). 120 GB is not a standard power-of-two size, though non-standard sizes might exist; typically, 120 GB is more common in SSDs, not pen drives. However, 128 GB is common. For exam, 120 GB is unusual, but I'd say it's not a standard capacity. I'll go with D as not typical.

Question #2
What is the primary architectural disadvantage of Dynamic RAM (DRAM) compared to Static RAM (SRAM)?
A. DRAM is structurally more complex and expensive per gigabyte.
B. DRAM consumes less power overall.
C. DRAM cannot handle multi-threaded processing requests.
D. DRAM requires periodic electrical refreshing which slows down access speed.

Correct Answer: Option D


Explanation:
DRAM stores data using capacitors, which lose charge over time. This design requires continuous refreshing cycles, introducing latency that makes it slower than SRAM.

What does the abbreviation 'SSD' stand for in modern computer hardware technology?
A. Solid State Drive
B. Synchronous System Drive
C. Silicon State Device
D. Static Storage Drive

Correct Answer: Option A


Explanation:
SSD stands for Solid State Drive. It is called 'solid state' because it contains no moving mechanical components, relying instead on solid-state electronics.
