What is the smallest logic allocation unit of data storage on a hard disk drive recognized by an operating system's file system?
A. Platter
B. Cluster
C. Sector
D. Track
Answer: Option B
Solution (By JKSSB Mock Tests)
A cluster (or allocation unit) is a group of sectors combined by the operating system's file system to form the smallest legal space where a file can be stored.
Which system component acts as an intermediary buffer, allowing slow peripheral storage devices like hard drives to communicate efficiently with the CPU?
Explanation:
Disk buffers built into drives act as localized memory arrays to cache data temporarily, preventing slow mechanical read speeds from bottlenecking system processes.
Explanation:
DRAM stores data using capacitors, which lose charge over time. This design requires continuous refreshing cycles, introducing latency that makes it slower than SRAM.
