Question

Match List I with List II.

List I	List II
A. Segmentation	I. Memory is viewed as a collection of logical address spaces.
B. Unsegmented paged memory	II. Virtual address is the same as the physical address.
C. Segmented unpaged memory	III. Memory is viewed as a paged linear address space.
D. Segmented paged memory	IV. Manages the allocation of memory within a partition.

• (A) - (I), (B) - (IV), (C) - (III), (D) - (II)
• (A) - (V), (B) - (II), (C) - (I), (D) - (III)
• (A) - (III), (B) - (IV), (C) - (II), (D) - (I)
• (A) - (IV), (B) - (III), (C) - (II), (D) - (I)

Hint:

Unsegmented memory maps directly to physical memory, while segmented and paged memory applies divisions for logical management.

Answer 1

The Correct Option is A

In unsegmented unpaged memory (A), virtual addresses are identical to physical addresses, with no paging or segmentation. This corresponds to (A) - (III). Unsegmented paged memory (B) views memory as logical address spaces, divided through paging. This corresponds to (B) - (II). Segmented unpaged memory (C) divides memory into segments without paging, presenting virtual memory as a collection of segments. This corresponds to (C) - (IV). Segmented paged memory (D) uses both segments and pages, forming a paged linear address space. This corresponds to (D) - (I). Thus, the correct option is: 1.(A) - (III), (B) - (II), (C) - (IV), (D) - (I).
