What is the function of an asset known as a 'Solid State Hybrid Drive' (SSHD)?
A. A conventional mechanical hard drive featuring a small integrated flash memory cache buffer.
B. A memory unit that toggles between RAM and ROM modes on demand.
C. A cloud backup server setup using physical tape media archives.
D. A drive combining physical optical disc trays with flash memory chips.
Answer: Option A
Solution (By JKSSB Mock Tests)
An SSHD combines a traditional high-capacity mechanical hard disk with a small amount of fast solid-state flash memory to cache frequently accessed files, blending capacity and speed.
Explanation:
ROM is non-volatile and retains data without power. However, for long-term storage, hard disks and SSDs are more common; ROM is typically used for firmware. Among the options, ROM is non-volatile.
Explanation:
A write buffer holds data to be written to memory, allowing the CPU to continue execution while the write operation completes asynchronously.
