What is the primary operational objective of implementing a 'Write-Through' design pattern inside a CPU cache architecture? MCQ with Answer and Explanation
What is the primary operational objective of implementing a 'Write-Through' design pattern inside a CPU cache architecture?
A. To bypass the main memory entirely during computational loops.
B. To force data straight into external backup clouds.
C. To write data to both the cache block and the main system memory simultaneously to maintain data consistency.
D. To accelerate data deletion routines.
Answer: Option C
Solution (By JKSSB Mock Tests)
A write-through cache policy ensures that whenever data is modified in the cache, it is immediately written to the main memory as well, maintaining data synchronization across levels.
Explanation:
Dynamic RAM (DRAM) stores data in capacitors which lose charge over time, hence it requires continuous refreshing to maintain data integrity.
Explanation:
64 GB is a common capacity for USB drives in 2026, though larger sizes like 128 GB and 256 GB are also common. 128 MB and 4 GB are outdated for mainstream.
