Which of the following is a characteristic of a hard disk's cylinder?
A. A single track on one platter
B. A storage area for file allocation table
C. A set of tracks that are at the same radial position on all platters
D. A group of sectors
Answer: Option C
Solution (By JKSSB Mock Tests)
A cylinder consists of the same track number on each platter in a hard disk drive, all at the same distance from the center. This allows the heads to access data without moving.
Explanation:
For DDR memory, the effective data rate is often quoted in MT/s (megatransfers per second), which indicates the number of data transfers per second. MHz is clock frequency, which is half of MT/s for DDR.
Explanation:
NAND flash memory is erased in blocks, making it suitable for high-density storage like SSDs and USB drives. NOR flash allows byte-level access but is slower for writing.
