What is the primary advantage of an SSD over a traditional hard disk?
A. No moving parts, faster access
B. Longer lifespan
C. Lower cost per GB
D. Higher capacity
Answer: Option A
Solution (By JKSSB Mock Tests)
SSDs have no moving parts and use flash memory, providing much faster read/write speeds and lower latency compared to HDDs, which rely on spinning platters and mechanical heads.
Explanation:
The memory hierarchy is designed to provide a trade-off between speed (fast but expensive) and capacity (slow but cheap), optimizing overall system performance and cost.
Explanation:
A dual-layer DVD (DVD-9) holds about 8.5 GB (or 7.95 GiB). Single-layer is 4.7 GB. Some double-sided DVDs have more, but standard dual-layer is 8.5 GB.
