What is the approximate data transfer rate of a typical 7200 RPM hard disk drive?
A. 50-80 MB/s
B. 100-200 MB/s
C. 500-600 MB/s
D. 1-2 GB/s
Answer: Option B
Solution (By JKSSB Mock Tests)
Modern 7200 RPM HDDs typically have sustained transfer rates in the range of 100 to 200 MB/s, depending on density and technology. SSDs are much faster.
Explanation:
The address bus is a directional pathway used exclusively by the CPU to point to the specific hardware memory address location it wants to interact with.
Explanation:
SSDs use non-volatile flash memory, have no moving parts, and deliver significantly higher read/write speeds compared to traditional HDDs.
Explanation:
NVMe stands for Non-Volatile Memory Express. It is a communication protocol developed specifically for accessing high-speed storage media, like SSDs, via PCIe lanes.
