What is the storage capacity of a typical 3.5-inch hard disk drive in 2026?
A. 100 GB
B. Only 500 GB
C. Typically 1-8 TB
D. Up to 10 TB
Answer: Option C
Solution (By JKSSB Mock Tests)
As of 2026, 3.5-inch HDDs commonly range from 1 TB to 8 TB, with higher capacities available (e.g., 10-20 TB) but 1-8 TB is typical for consumer drives.
Explanation:
The memory address space is the set of all possible memory addresses that the CPU can generate, limiting the maximum amount of memory that can be addressed.
What structural issue happens when data files are written, deleted, and modified repeatedly, causing a mechanical hard drive's storage space to become scattered across non-contiguous areas?
Explanation:
Fragmentation occurs when files are broken up and saved in scattered, non-contiguous clusters across a mechanical disk, forcing the drive heads to move more and slowing access times.
Explanation:
15,000 RPM drives are high-performance, typically used in enterprise environments for demanding applications, with lower capacities and higher cost.
