Which term describes the operational condition where a CPU is constantly swapping memory pages between RAM and disk, leading to massive system slowdown?
A. Paging
B. Thrashing
C. Caching
D. Multiprocessing
Answer: Option B
Solution (By JKSSB Mock Tests)
Thrashing occurs when virtual memory resources are overused, causing the OS to spend more time moving data between disk and RAM than executing actual application instructions.
Which memory management scheme breaks physical memory into fixed-sized blocks called 'frames' and logical memory into blocks of the same size called 'pages'?
Explanation:
Paging splits physical memory into fixed-size chunks called frames and logical process space into pages of equal dimension, avoiding external fragmentation.
