Which of the following options represents a core feature of asymmetric multiprocessing (AMP)?
A. Memory is physically isolated and cannot be read by any processor core.
B. A master processor schedules tasks and distributes distinct workloads to specific slave processors.
C. All processors have completely equal priority and share all resources.
D. No two processors can be active inside the motherboard enclosure at the same time.
Answer: Option B
Solution (By JKSSB Mock Tests)
In Asymmetric Multiprocessing (AMP), there is a master-slave structure where a single master controller processor manages system resources and schedules tasks for subordinate processors.
Explanation:
A process that has finished execution but still has an entry in the process table is a 'Zombie' process, waiting for its parent to read its exit code.
In operating system concepts, what does 'Belady’s Anomaly' describe?
A.A process scheduling glitch where higher priority threads starve indefinitely.
B.A network protocol lockup scenario.
C.A file allocation bug where small files corrupt the master partition table.
D.A phenomenon where allocating more physical memory frames results in an increase in the number of page faults for certain page reference strings under FIFO replacement.
Explanation:
Belady's Anomaly shows that for certain page reference streams under the First-In-First-Out (FIFO) replacement scheme, adding page frames increases page faults.
