Which of the following is a characteristic of flash memory used in SSDs?
A. It has a limited number of write cycles
B. It is volatile
C. It is more expensive per GB than HDDs but faster
D. It is slower than HDDs
Answer: Option A
Solution (By JKSSB Mock Tests)
Flash memory has a finite number of program/erase cycles, affecting SSD lifespan. It is non-volatile, faster than HDDs, and typically more expensive per GB.
Explanation:
Web pages can be cached in browser cache (on disk), memory, and also in disk cache. The question is ambiguous, but typically browser cache is on disk. However, all are forms of caching.
Explanation:
Cache memory is volatile; it loses data when power is off. It is small, fast, and located close to the CPU to bridge the speed gap between CPU and RAM.
Explanation:
The system clock provides a timing signal that synchronizes the operations of the CPU, memory, and other components, coordinating data transfers.
