What structural concept prevents an application from directly modifying memory frames allocated to another independent active process?
A. Memory Protection (via Page Permissions)
B. Context Switching Delays
C. Spooling Buffer Layers
D. Asymmetric Slicing
Answer: Option A
Solution (By JKSSB Mock Tests)
Memory protection schemes utilize hardware page tables and boundaries to prevent processes from accessing or corrupting another process's memory space.
Explanation:
Spooling (Simultaneous Peripheral Operation On-Line) uses a buffer to hold jobs for slow peripherals, allowing overlapping of I/O with processing.
