| List I | List II |
|---|---|
| (A) Paging | (I) Evicts least recently used page |
| (B) LRU (Least Recently Used) | (II) Extends physical memory |
| (C) C-SCAN | (III) Logical to physical mapping |
| (D) Virtual Memory | (IV) Circular disk access |
Pick an option to check yourself, or open the answer below.
Show answer & explanation
Correct answer: B. (A)-(III), (B)-(I), (C)-(IV), (D)-(II)
Explanation
Paging maps logical to physical addresses (III), LRU evicts the least recently used page (I), C-SCAN gives circular disk access (IV), and virtual memory extends physical memory (II).More System Software and Operating System questions
