Which term describes the file area on a hard drive that the operating system allocates for virtual memory use when physical RAM capacity runs out?
A. Directory File
B. Page File / Swap File
C. Index Table
D. Root Partition

Solution (By JKSSB Mock Tests)
The operating system maps out a dedicated storage partition or hidden file structure on secondary drives, known as a page file or swap file, to manage virtual memory overflows.
What type of computer memory is specifically designed to detect and correct single-bit data corruption errors in critical enterprise server environments?
Explanation:
ECC (Error-Correcting Code) memory contains extra data bits that allow the memory subsystem to identify and fix single-bit memory errors on the fly, preventing system crashes.
Explanation:
Cache memory holds frequently accessed data and instructions to reduce the average time to access data from main memory, thus improving system performance.
Explanation:
ROM (Read-Only Memory) is non-volatile, retaining data even when power is off. RAM and cache are volatile; registers are volatile as well.
