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

Unsegmented unpaged memory (A): In this type of memory, the virtual address is the same as the physical address, and no paging or segmentation is done. So, the correct match is (A) - (III). Unsegmented paged memory (B): Memory is viewed as a collection of logical address spaces, and paging is used to divide the address space. The correct match is (B) - (II). Segmented unpaged memory (C): Memory is divided into segments, and there is no paging. Virtual memory is viewed as a collection of segments. The correct match is (C) - (IV). Segmented paged memory (D): Memory is divided into both segments and pages. This means that memory is viewed as a paged linear address space. The correct match is (D) - (I). Thus, the correct option is: 1.(A) - (III), (B) - (II), (C) - (IV), (D) - (I).
